Antimony CAD is something different!

Antimony is new open source CAD developed by Matt Keeter. Design in Antimony is done by connecting nodes in a graph, each node is defined by a customizable script and nodes usually represent a primitive shape or transform.
It is still under development and it is not meant as a professional CAD software for higher level applications. It will be interesting to see how it will develop in the future.
If you are enjoying OpenSCAD or any other programmatic CAD (and probably have a slight masochistic note) you will want to try this as an alternative.

It is described as:
Antimony is a computer-aided design (CAD) tool from a parallel universe in which CAD software evolved from Lisp machines rather than drafting tables
... but you will understand it better when you watch the video:




It currently runs on Linux and Mac but you can get it on Windows with help of a virtual machine.

Make your own aluminum frame Ultimaker 2 clone

Jason developed Ultimaker 2 clone made with aluminum extrusion frame and 3d printed parts. According to his posts it work very well.

He describes it as:
This is not The Greatest UM2 Clone, no.
This is just a tribute.
This project began as a fun way to learn AutoDesk Fusion 360. I started by importing the entire Solidworks CAD file into a new Fusion 360 project, dropped the frame (walls) from the printer, built 20x20 Misumi aluminum extrusions to wrap the printer guts and then worked to build brackets to support all the parts that previously attached to the frame.
I've been printing nonstop on this new printer with the same precision and quality as my real UM2. In fact, I can use the same GCODE in either machine with identical results.

DIY digitizer with detailed construction guide

Nikolaj Møbius from Fablab RUC developed a simple and cheap DIY digitizer 3d scanner that can record points in a physical space and convert them into a 2D vector drawing for laser cutting or 3D printing.
It is made with three rotary encoders and gets a points measures controlled by Arduino. Since it currently does only measures more suitable for 2D capture it is ideal for CNC or laser cutting with very good results.
Since the software is in early development phase we can expect better 3d scanning or 3d point cloud capture soon.





Check out the project homepage with very detailed build guide and software:

http://fablab.ruc.dk/diy-digitizer/

It looks very easy to build even for the beginners.

Here is the description of current limitations:
So far the system is designed to record a 2D surface and convert it into a PDF vector file. The Z axis is simply ignored in the output. Since the system actually records in a 3D space it is possible to export a 3D object for post processing. This is mainly a matter of implementing a another export method.
However, since the arm is not able to reach around an object in a 3D space it will not be possible to record all the points necessary to make a full 3D object (Update: In the source files we have a version with a rotating platform now). One possible workaround would be to implement a rotating base which would enable the arm to approach the object from all sides. Further, the software is only a usable prototype, but could be evolved into a much more solid tool.
I like the plywood frame arm!

NASA 3D Printed Habitat Competition

Here is a great competition with some big prizes. NASA wants you to help them explore and inhabit the space with help of 3d printing! I wish you the best of luck if you are going to compete!










Competition details from the NASA page:
NASA and the National Additive Manufacturing Innovation Institute, known as America Makes, are holding a new $2.25 million competition to design and build a 3-D printed habitat for deep space exploration, including the agency’s journey to Mars.

The multi-phase 3-D Printed Habitat Challenge, part of NASA's Centennial Challenges program, is designed to advance the additive construction technology needed to create sustainable housing solutions for Earth and beyond.

The first phase of the competition runs through Sept. 27. This phase, a design competition, calls on participants to develop state-of-the-art architectural concepts that take advantage of the unique capabilities 3-D printing offers. The top 30 submissions will be judged and a prize purse of $50,000 will be awarded at the 2015 World Maker Faire in New York.

The second phase of the competition is divided into two levels. The Structural Member Competition (Level 1) focuses on the fabrication technologies needed to manufacture structural components from a combination of indigenous materials and recyclables, or indigenous materials alone. The On-Site Habitat Competition (Level 2) challenges competitors to fabricate full-scale habitats using indigenous materials or indigenous materials combined with recyclables. Both levels open for registration Sept. 26, and each carries a $1.1 million prize.

How to convert G-Code back into STL?

I've been researching methods to convert pure G-Code back to STL / .OBJ, and it seems that there are not many options but it can be done.

G-Code Reverser by MakePrintable

Even in its beta version it looks the most developed out solution.

Here is the Reverser description:
The Generated G-Code commands represent horizontal layers “slices” of the 3D model, sliced as the model was placed, scaled, and rotated in the slicing software’s platform, those commands are generated with user and printer-specific settings, all of which makes the G-Code almost impossible to modify in order to retarget different printers, let alone modifying the original model itself.
Our Reverser interprets the G-code, and collects the details and data needed from the commands, then it regenerates the 3D model which represents the outcome of the printing process using the respective G-code file.
This feature allows users to reuse G-code, by regenerating the G-code using the Reverser’s outcome, and simply changing the settings, or even target other printers than the one targeted in the G-code file.
Power users and 3D designers would get the chance to modify the model once more, as the outcome of the Reverser would be in .OBJ or .STL formats, which means they can import it into 3D editing software and start with their editing.




Blender GCode Reader Add-on and GCodeImport
https://github.com/zignig/blender-gcode-reader

http://www.thingiverse.com/thing:6236

New version: https://github.com/iraytrace/BlenderGcodeImport


There are some solutions that enable G-Code visualization and / or printing simulation like but not conversion or export to STL:

GCode2Vtk that displays g-code like VTK 3d model.

https://github.com/pbrier/gcode2vtk

GCode Analyzer/Visualizer
http://www.thingiverse.com/thing:35248

http://gcode.ws/

CNCSimulator can simulate 3d printering out of g-code

http://cncsimulator.com/




Repetier Host seems to be able to simulate g-code in 3d model bu I'm not expert on it.

If you know any other methods to convert g-code back to STL let me know so I can update this post.





















Update:

Could this be used to hack 3d model streaming services? A kind of a workaround?
There are services like Pinshape that use "streaming" as a sort of DRM that enable you to print an object without downloading it in order to preserve the original .stl object and prevent sharing or piracy.
Theoretically you could us a sort of custom Marlin that only reads the g-code and records it and you could use g-code reverser to make an original STL.

Here is an example of streaming service:



Source blog post about streaming function:

DRM systems always fail and punish only a paying customer.


IndieLC compact DIY 3d printer with linear bearings

IndieLC is a compact DIY 3d printer that uses linear bearings. It is small in footprint but has relatively large print volume for its size.

Key features:
  • Lightweight and Portable – To be transportable I wanted to keep the weight as low as possible though still keep the functionality of the printer. For this reason I decided to base the design around the smaller Nema 14 stepper motors that provide more than enough torque. I also designed the printer so that it can be flat packed by splitting it down to the 3 main axes to be safely stored in a case for transport.
  • Versatile – To be able to increase the adaptability of the printer for use with different types of materials (PLA/ABS etc) and allow further development of the use of these materials I wanted to incorporate a heated bed so decided to incorporate the RepRapPro heated PCB. This would also alleviate any potential bed adhesion problems.
  • Stable – With each printer I have previously built the weakness has been the stability of the Z axis as a result of the motion of the X axis. With the crane style design only having one Z axis support I wanted to minimize the weight being transferred across this axis and so I incorporated the use of a Bowden system with the RepRapPro hotend.
  • Neat – Having gained experience with routing wires, and finding that due to repetitive motion of the axes failed joints or broken connections interrupted the use of the printer, I decided to use flat core cable like I first saw used on the Mendal 90. This has proved a much more reliable method for wiring.
  • Noise – After using Linear Bearings for motion on all my other printers I decided to try using wheels and bearings to reduce noise and found Openbuilds V-slot system to be a suitable choice.
  • Efficient – Larger flat plates are made from laser cut acrylic as it provides a good balance between accessibility, strength, cost, weight and aesthetics. It reduces build time as to 3D print these would take a lot of time and I didn’t want to spend ages printing what were essentially 2D parts! The 3D printing is saved for the more complex, intricate designs. Additionally I feel people have greater accessibility to laser cutters versus other manufacturing options.
  • Print Area – The printable area of the printer is 140x140x140mm which is large compared to the overall size of the printer – making the most of the space available.

Autodesk releases files for Ember 3d printer

Autodesk made all the mechanical files for their Ember SLA 3D printer publicly available making it open source. It comes shortly after they have open sourced the PR48 resin for it. The Ember itself proved to be very hackable.

Why did they do it? Maybe to gain market for their Spark platform? As a sort of move against competition? Who knows ...  How will other companies like FormLabs react? That will be interesting! I see that SLA is the new field of growth and competition and we can certainly hope for much more new machines and materials coming soon.







Here is what Autodesk team writes about this move:
With these design files, you can conceivably make your own Ember. However, many of Ember's parts are injection molded, and while it is possible to 3D print these parts (many of Ember's first prototypes were largely 3D printed -- there's a certain beauty in a 3D-printed 3D printer), it's probably more work and ultimately more expensive than buying an Ember. The same is true of the projector -- having a Fusion model of the projector won't help you make your own, but that's not the point.
Our thought is not that you would duplicate Ember, but extend it. The design files allow you to make your own modifications and enhancements. For example, we'd love to see Ember used as a research platform to explore the next-generation of stereolithography.

Large volume Printrbot Pro and Printrbot Crawlbot CNC

Brook Drumm of Printrbot published information on two new machines:

Printrbot Pro 

Technical specifications:
  • Around 2' cubed build volume. 
  • Heated bed.
  • Dual extruder (all metal Ubis hotends, v2 Alu extruder, Alu gear head extruder in the works... Print in any material available today)
  • Optional enclosed build chamber.
  • LCD panel
  • SD card slot
  • Dedicated heatbed controls
  • LED lights
  • Actually fits through most doors ;)




Here is what Brooks writes about it:
I have wrestled with this monster for over a year. I build 5 prototypes from scratch and hated them all. The last one was too ambitious with servos and ballscrews... That last one printed beautifully after, oh, SO much work, but I tore it down the next day and went back to the drawing board... Hacking together a totally new design in a couple days from spare parts lying around-- #6. That served as the model for this fine specimen - #7. Thanks again to Steve, Nick, Mark and Caleb.
The Printrbot Pro is aimed at those who want a very large build volume but don't want to pay the big bucks for other options out there.

It's also the most expensive printer we have ever made, but will be less than the MB Z18. But, not gonna kid ya, shipping will kill you.
We will post pics, video and details immediately. We won't have it at Makerfaire, though. After reviewing it today, I have some details to refine after we get back... Then it's ready for prime time.

We will sell this bot a bit differently... Doing a waiting list and making them one at a time. I may actually interview the potential buyers to be sure of a good fit. We hope to keep a slow steady pace with this one since the market is presumably small. I have a handful of clients already lining up... Really interesting to hear what people plan to do with them! It is intended for businesses and education.
The shop is a buzz about what we all want to print on this thing. The next one we build is for me ;)
Printrbot Crawlbot CNC

Here is what Brook writes about it:
Printrbot Crawlbot lives. It’s big and it’s small. A Cnc router that cuts 4x8′ material, yet occupies a small footprint in your garage. CAD/CAM software included.
Details, pics and video soon to follow. See it live at Maker Faire in a couple days. Price not yet set.

It's still early, but the world will see it in a couple of days anyway. Even though there is a punch list of things to refine, I wanted to share it on the first day I saw it cut with its own software.
That's right, Printrbot makes software, thanks to Mick and Sean - the two newest members of the Printrbot family. Mick is the coder / maker in the pic.

Crawlbot will feature cloud-powered project sharing-- software that runs in your browser but works offline too. Tinyg and raspberry pi team up to run the show here. Mick been working on the software for months. The hardware idea was the usual Brook and Brian brainstorm followed by boots on the ground making it a reality. Thanks to Steve (lead), Mark, Nick, & Caleb.

Designed completely in Fusion 360, btw.
We think you are gonna like it.

How to make a DIY Stewart Platform with 3d printed parts

Stewart platform is a multi-purpuse robotic platform that is movable in six axis. This machine could be used in all sorts of project where you need multiaxial kinematics. I could see it even being used as part of a 3d printer.

Nicholas Pajerski made a tutorial on Instructables describing how to build a desktop Stewart platform with lasercut and 3d printed parts. It is controlled by Arduino and uses linear actuators enabling it to carry heavier loads.




Detailed build guide and all the parts files can be found at:

Rise of 3D Printing Factories and a Future without Work

CloudDDM is a company that operates like most 3D printing services where you can order parts through a web interface, but they're able to produce any part at high volumes and speed. They've recently opened a 3D printing factory inside UPS international hub in Louisville USA with one hundred 3D printers and plans to increase to a thousand. The machines run 24/7 and all the logistics are handled by UPS. They print in several materials like ABS, Polycarbonate (PC), Polycarbonate-ABS (PC-ABS) and ULTEM 1010 with several color options.

Now the truly amazing (or frightening) thing about this factory is that it is highly automatized and operated by only THREE WORKERS! 3 people! 3! One per eight-hour shift! Is this a new trend? Factories without ANY workers?

Lets see what other players are doing...

GE is a well-known aerospace 3D printing manufacturer and here is how they see future of work:




Lots of 3d printers and robots producing and only a few people designing and carrying furniture. They look out of place and almost like a decoration. I'll write about future of design work in the future post about this topic ... but don't think machines can not design stuff also ...


Materialise has a 3D printing "factory" facilities with what looks like more people working:




But this is not a pure "factory" but more diverse design and production center with design, product development, and engineering personnel. Another point is that they probably displace many "traditional" workers as they use cutting-edge technology and logistics. Maybe even several orders of magnitude more than they employ. If you look closely you will find that even some of the workplaces showed in this video could be automated now or replaced by machines in a couple of years.

Are we seeing a start of 3D printing factories replacing industrial workers? In the '90ties during the first dot-com bubble, people predicted that the postal services will disappear because of email communication but they were wrong since they took over the much increased package shipments due to the rise of e-commerce. Could this happen again with increased volume of 3D printed products? Probably not. 
Why?

Because the whole transport logistic sector is getting automatized! Deimler just presented their autonomous truck and the state of Nevada is supporting it with new autonomous vehicle legislation. Even the company said it will take some 10 years to have fully autonomous trucks on the roads with major regulatory obstacles but they are moving in that direction with most of the other tech companies like Tesla and Google. Do keep in mind that "truck driver" is the most common profession in the USA with more than 9 million employed in the trucking industry or 1 in every 13 employed Americans.





Is this onset of technological unemployment unfolding in real life? Technological unemployment (or desourcing) is defined as a process of unemployment being caused mainly by technological advances. It is a controversial theory that has yet to be confirmed or disproved.

In 2014 Pew Research surveyed 1,896 technology professionals and economists and found a split in opinions: 48 percent of them believed that new technologies would displace more jobs than they would create by the year 2025, while 52 percent maintained that they would not. The implications of it being a reality would have a HUGE societal impact on a global scale. What jobs are future proof?




Future will be interesting. Stay smart and think about all the possible scenarios!

As I live in a country with very high unemployment I have a very personal interest in this topic and I think it is very important to investigate it and stay informed about it.

Since this post drew a lot of attention and there were many interesting developments, I've decided to try to document further developments and new 3D factories being built:


Update (07.02.2016.):

Siemens opened first European 3d printing factory in Sweden.  The €21.4 million facilities, located in Siemens industrial plant in Finspång, Sweden will have 20 employees and multiple industrial grade metal 3d printers. The factory will produce prototypes, end-product parts and replacement parts for repair focused on gas turbines.
Thorbjorn Fors, global business director for Distributed Generation at Siemens, said of the facility:
“With this investment, we can develop new and improved components and repairs, for example burner tips to serve our industrial gas turbine SGT-800, significantly faster. Using this innovative approach, we will shorten repair times from months to weeks. It is an important step in our ability to respond to the needs of our customers.”
Full press release in Swedish.

As we see there are more 3d printing factories being built with a very small number of workers. This is also a start of the change in the Europe.

Siemens 3d printing factory in Sweden. Looks very clean. And empty of people. 



Update (15.04.2016.):

There are more 3D printing factories and production/prototyping centers being opened all over the world:

Airbus opened one in the Ludwig Bolköw Campus near Munich.

From the source:
The Aerospace Factory, as the new 3D printing center at the facility is being called, will be based out of the Ludwig Bolköw Campus, an industry and university collaborative venture located on-site. The location will be used to research the 3D printing of endparts for use in aerospace through work performed by a number of important players including: Airbus Safran Launchers; metal 3D printer manufacturer EOS; engine maker MTU Aero Engines; the Technical University of Munich and its Institute for Machine Tools and Industrial Management; Airbus Group Innovations; the Fraunhofer Development Center for X-ray Technology (EZRT); Industrieanlagen-Betriebsgesellschaft mbH (IABG); Airbus subsidiary APWorks; virtual prototyping firm the ESI Group; and the Airbus Endowed Chair for Integrative Simulation and Engineering of Materials and Processes (ISEMP) of the University of Bremen.

GE opened 200 M USD advanced manufacturing center in Pune, India.

From the source:
In 2015, GE unveiled its $200 million, Multi-Modal advanced manufacturing facility in Chakan, Pune, part of the western Indian state of Maharashtra. Dubbed a “brilliant factory” by its creators, the facility was established to produce jet engine parts, locomotive components, wind turbines, and a host of other additively and traditionally manufactured components for a number of GE companies. The facility now employs around 1,500 workers, responsible for operating 3D printers and other machinery. "The idea is to service a multitude of businesses—from oil and gas, to aviation, transportation, and distributed power—all under the same roof," said GE's Amit Kumar, overseer of the Multi-Modal facility, via TechRepublic.
The Multi-Modal facility provides GE with several advantages. By bringing a number of interconnected operations under one roof, the company will allegedly save up to ten times as much money than if it had established individual facilities for separate business lines. The facility is also helping to bring plastic and metal additive manufacturing technology to its India operations, an advancement which offers the company huge flexibility and cost-saving potential.

Eventually, the Pune facility will produce critical end-use components such as the jet engine fuel nozzle, but it will first service a more urgent need: 3D printing replacement parts for broken machinery—parts that would otherwise have to be made in bulk and stored, or sourced from an external supplier. Replacement parts, especially for older appliances, can be incredibly difficult to source when those appliances are discontinued or simply made in small quantities. 3D printing these replacement parts is much faster than producing them using traditional manufacturing techniques, with previous timescales of three to five months reduced to around one week when additive manufacturing is implemented
Can you spot a single human worker?

Update (27.06.2016.):

GE Oil & Gas is opening new 3D printing factory line with advanced robotics in Talamona, Italy. It is investing some 10 million USD in new production lines to 3D print burners for gas turbine combustion chambers and other advanced components such as nozzles. These new advanced manufacturing lines establish this site as a center of excellence for the oil and gas industry. It also used advanced production software to manage the factory.
“The use of automated production and new techniques like additive manufacturing allow us to develop parts and products more efficiently, precisely and cost-effectively, accelerating the speed at which we can bring product to market,” said Davide Marrani, general manager for manufacturing for GE Oil & Gas’ Turbomachinery Solutions business line.

“The opportunities for the application of additive manufacturing and 3D printing in the oil and gas industry are only just starting to be explored, and it will require an ongoing rethink of component design and production approach,” said Massimiliano Cecconi, GE Oil & Gas Materials & Manufacturing Technologies Executive.

As factories as growing so is the software ecosystem that connects them B2B and B2C. Fast Radius has developed "virtual inventory" software for their 3d printing factory. It enables companies to deliver parts "on demand" and "just in time". Rick Smith from Fast Radius said:
“On average, the rule of thumb for the cost of holding physical inventory is about 25 percent the cost of the part per year,” he explained. “There is a significant cost in terms of cost of capital, warehousing space, security and damage. The other major problem with physical inventory is that you’ve got to produce in large volumes to get the unit costs low. This works great when you’re producing iPhones and you know you’re going to sell 10 million of them. But, when all of a sudden you’ve got an essential part and you know you’re only going to need 15 of them per year—maybe it’s a critical part to a machine in a manufacturing operation that doesn’t break very often, but is extremely important when it does break—then it doesn’t make sense to go through the setup and all of the costs related to doing a larger-scale production.”
The centralized manufacturing model of the 20th century may not be done away with soon, but the shift is already under way. To introduce its 3D printing services to potential OEMs, Fast Radius has partnered with about a dozen companies that are looking to make the shift to a virtual inventory. “To start,” Smith explained, “the companies that we’re working with are identifying 1,000 or 1,500 parts that are excellent candidates for on demand production. This may be a small percentage of their overall inventory, but as costs drop precipitously and quality continues to rise over time, these companies know that a larger and larger percentage of physical inventory will be moved to a virtual inventory model.”

How to make DIY ultrasonic vapor polisher for 3D printed objects

Micheal, well known for his TestrBot made another useful and easy DIY project that enables you to build ultrasonic vapor polisher for your 3d printed objects.






























Here is the project summary:

What's needed is a better solvent application method, and that's what this Instructable is about.
The current vapor polishing methods and their drawbacks include:
  1. Hot treat via boiling solvent in a crock pot or similar chamber (Potentially dangerous and very hands-on process)
  2. Cold treat via slow release of solvent from paper towels in an enclosed container (Very time consuming, can't observe parts during this process.)
  3. Spray canned solvent aerosol onto part. (Inconsistent surface finish, must be done outside)
  4. Dipping parts directly into liquid solvents (Unpredictable/inconsistent finish, Likely over exposure of part)
All I wanted is a machine that lets me quickly drop parts into a transparent container and be able to press 'go' and have the machine produce a predictable finish on its own. I do not want to have to put together a really involved setup that may be a fire hazard, fume hazard, or something that produces unpredictable surface finishes. Essentially I want something as convenient as a microwave. I'm also forgetful so I don't want my parts to be destroyed if I forget that I left them in the machine.
The Ultrasonic Misting 3D Vapor Polisher is the solution to all of these problems.
This key component of this machine comes from ultrasonic humidifier, which uses a piezoelectric transducer (like a speaker) to create a high frequency mechanical oscillation in a liquid. This vibration forms an extremely fine mist of droplets in a fog/mist. The density of the fog is controlled by varying the intensity of the vibrations via a potentiometer.
This fog mist is very dense and wont move far on its own, so I used an aquarium air pump to blow it from the misting chamber into the glass finishing chamber where it can condense on the 3D printed part. This airflow keeps the air moving inside the finishing chamber, which helps produce a consistent finish on the part. The airflow system is open by necessity but we do not want the exhaust air to become a fume hazard so there is a water bubbler on the exhaust to absorb excess solvent. (Note that this only protects you when using water miscible solvents such as acetone.)

Here is the video of machine in action and results of the treatment:



Detailed build guide can be found here:

http://www.instructables.com/id/Ultrasonic-Misting-3D-Printing-Vapor-Polisher/

Here are results of strength tests with lots of charts:

http://www.instructables.com/files/orig/FQQ/HMAJ/I98BK9P2/FQQHMAJI98BK9P2.pdf

Conclusion was:
The vapor treatment resulted in a consistent overall weakening of the test specimens. Specimens that had not been treated with Acetone vapor had an average yield stress 24% higher than those treated with the vapor.
Solvents that can be used to polish different materials:
  • ABS: Acetone
  • Acrylic: Most Solvents
  • PLA: MEK or 'MEK Substitute'
  • PVA: Water
  • PVC: Most Solvents
  • Polycarbinate: Pretty solvent resistant
  • Nylon: Pretty solvent resistant
  • Polypropylene: Pretty solvent resistant
  • Polyethylene: Pretty solvent resistant

Stay safe people! Chemicals are dangerous! You can check this chart showing dangerous combinations:

OPAM water cooled metal hot end

OPAM is a new all metal jot end with water cooling from Singapore developed by Leong Khit. It will be open sourced when the Indiegogo campaign finishes.

The design is simplified by:
  • Combining the nozzle, heater block and heat sink into 1 single piece of SS304
  • Using water cooling as it is far more effective than air cooling
  • Removing any PEEK or PTFE material
The benefits of a One Piece design are as follows:
  • No leaks/jams between the nozzle and heater block's contact surface
  • No galling of the nozzle's thread (since it is built-in as part of the design)
Key Features:
  • 1 piece construction (the nozzle, heater block & heat sink is combined into 1 single piece of SS304) to eliminate jams
  • Water-cooled for high temperature extrusion of up to 350°C
  • Short & Sharp transition from cold to hot portion (just 4mm)
  • Built-in stainless stain nozzle
  • Compact design (Light weight of 40 grams) for high speed printing
  • Price: 60 USD for early-bird backers on IG



It is on Indiegogo now:

How to design for dual extruders with FreeCAD

Here is a great video tutorial on how to use FreeCAD to design two colored (or dual material or support structures) 3d objects for dual extruders. It could be also used for other CAD programs.




Tutorial was made by Jurgen Gaeremny.



DIY contact 3D scanner with Arduino and FreeCAD

Here is a nice little 3d scanner made from various scrap parts and Arduino. It is a simple contact 3d scanner that produces a pint cloud in FreeCAD.

It uses only three potentiometers and two steel rods,  and the same potentiometers are also rotational joints. Arduino is sending the current value of the potentiometers to the python script, which calculates the mechanism position and draws the points inside FreeCAD.

This device was developed by Javier Martinez Garcia from Spain.



Here is the video of it in action scanning a toy car:
