Cool 3D Printed Mesh Frame Bicycle

This bicycle looks very cool! Does anyone know more about it?

Update: it is probably not 3D printed but uses a carbon and kevlar woven istutruss system.

Here is a PDF document about isotruss structures:

Still, I was unable to find how exactly are they produced ...

They are wound and woven in complex machines:

DIY SLS 3D Printer Made For 400 Euro

Vulcaman from Germany developed a DIY laser sintering (SLS) 3D printer that you can make for some 400 Euro or 450 USD.

Technical specifications:

  • 1W 445nm laser diode
  • 8 x 8 x 8cm build volume
  • 36 x 54 x 60cm outer dimensions
  • CORE-XY movement
  • speed: 60mm/s tested, 300mm/s possible
  • costs around 400€

Video of the machine in action:

Since the nylon powder that commercial SLS printers use costs some 200€ per kilogram, developer used much cheaper black powder for powder coating. This gear was printed in black powder coating material at 60mm/s it has dimensions of 3 x 3 x 0,5cm and took one hour to print.

3D Printed Construction Mesh Structures

Here are some examples how 3d meshes can be used to reinforce building structures. This technique is probably much more useful and applicable then cement paste extrusion.

Mesh Mould uses steel wire:

Project description:
The research project Mesh Mould investigates the unification of reinforcement and formwork into a single robotically fabricated material system. During the first research phase a spatial robotic extrusion process was developed, allowing to examine the interdependencies of mesh typology and rheological behavior of concrete (see Mesh Mould 2012 - 2014).
The second research phase at the National Competence Centre in Research (NCCR) Digital Fabrication focuses on the translation of the structurally weak polymer-based extrusion process into a fully load-bearing construction system. The current research focuses on the development of a fully automated bending and welding process for meshes fabricated from 3 mm steel wire.
The research involves the development of a fabrication-, and structurally-informed mesh typology as well as the subsequent collaborative development of a specialized robotic end-effector together with the Agile & Dexterous Robotics Lab of Professor Jonas Buchli.
More information on this project can be found at:

digiFABTuring and their robot arm attached plastic extruder which is more similar to common 3d printheads and could be done in a home workshop:

Here is a complete wall system with 3d printed polymer matrix made by Branch Technology:

They 3D printed a 7-foot-tall-by-3-foot-wide wall in 30 hours, and are currently extruding at a rate of 1.5 pounds per hour. The wall has a spray foam insulation, concrete core and inside/outside finish layer.

How do robots make robotic babies?

Stork? No. WiFi and 3D printing. Obviously.

A team of scientists at Vrije Universiteit Amsterdam demonstrated how robots can evolve and reproduce. The first robot baby is a big step towards robotic ecosystems that can evolve in challenging environments. Two parent robots meet and exchange robotic DNA over WiFi which makes the baby in a 3d printer.

Original article in Dutch (Chrome Translate is your friend):

3D Printed and Laser Cut Open Source DIY Air Purifier

Ian van Mourik, a product designer from the Netherlands developed and open sourced an air purifier anyone can make. It is autonomous since it is controlled with Arduino and uses simple fans to move air trough particle filters and activated carbon.
It costs around 70 Euro. It has some laser cut parts from plywood but you could cut them manually or use different structural support since they are mostly decorative.
Looks like a great solution to improve your home air quality by removing dust and destroy mold particles or pollen (which I'm allergic to). Just keep in mind to change the filters or upgrade them with HEPA. Carbon filters get used up relatively fast.

Here is the video presentation:

Hadrian X Robotic Truck That 3D Prints Buildings With Bricks

Australian company "Fastbrick Robotics" developed a robotic truck system that can lay 225 bricks per hour. It's a big 3d printer on wheels that uses robotic crane to build houses.
It is not cement paste extrusion that can be found in other building 3d printers, but it is additive, digital and making BIG 3d objects.
Personally, I'm not even sure that cement paste extrusion is the best way to get commercially viable construction machine for industry wide adoption and application as a standard house building tool.

People like brick.

Here is an interesting video presentation:

World's Largest 3D Print from ORNL

Oak Ridge National Laboratory made the world's larges 3D print that was recognized by Guinness World Records.

From project description:
Researchers at the MDF have 3D-printed a large-scale trim tool for a Boeing 777X, the world’s largest twin-engine jet airliner. The additively manufactured tool was printed on the Big Area Additive Manufacturing, or BAAM machine over a 30-hour period. The team used a thermoplastic pellet comprised of 80% ABS plastic and 20% carbon fiber from local material supplier

The tool has proven to decrease time, labor, cost and errors associated with traditional manufacturing techniques and increased energy savings in preliminary testing and will undergo further, long term testing.

Here is the time-lapse video of the process and it looks impressive:

NinjaFlex 3D Printed Metamaterial Mechanisms

Team of researchers at Hasso Plattner Institute, Potsdam, Germany developed a technique that gives internal structure to objects that they printed on Ultimaker 2 in NinjaFlex filament. Since the structure is designed it gives the object mechanical movements enabling it to act as a tool or a device. 

From project description:
Recently, researchers started to engineer not only the outer shape of objects, but also their internal microstructure. Such objects, typically based on 3D cell grids, are also known as metamaterials. Metamaterials have been used, for example, to create materials with soft and hard regions.

So far, metamaterials were understood as materials—we want to think of them as machines. We demonstrate metamaterial objects that perform a mechanical function. Such metamaterial mechanisms consist of a single block of material the cells of which play together in a well-defined way in order to achieve macroscopic movement. Our metamaterial door latch, for example, transforms the rotary movement of its handle into a linear motion of the latch. Our metamaterial Jansen walker consists of a single block of cells—that can walk. The key element behind our metamaterial mechanisms is a specialized type of cell, the only ability of which is to shear.

In order to allow users to create metamaterial mechanisms efficiently we implemented a specialized 3D editor. It allows users to place different types of cells, including the shear cell, thereby allowing users to add mechanical functionality to their objects. To help users verify their designs during editing, our editor allows users to apply forces and simulates how the object deforms in response.

Personally I find that the software for design of those metamaterials is the most interesting part and would be of great use for DIY and Maker community. I don't know who has the property rights to that code, but I think if the research was funded by public money the code should be open sourced.

3dpBurner Open Source Laser Cutter and Engraver

3dpBurner is a DIY laser engraver and cutter project that uses 3d printed parts for the structural elements and movements. It also uses many standard parts like laser diodes and Arduino to make it work.

Here is what the developer writes about this project:
It is created with the same RepRap concept, by using 3D printed parts and some easy to find "vitamins" (non printed hardware).
I tried to design as cheap as possible, by using common electronics and a "low power" laser (a laser diode).
The X/Y working area is fully customisable by simply cutting the rods to desired length.
The max object height for working can be up to 50-60mm.
3dpBurner basically uses 3D printed parts, 8mm rods, M3/M8 hardware, some small bearings and a pair of GT2 pulley/belts. I got most parts from my "old" RepRap printer.
Motion is controlled by Arduino UNO, a CNC shield and a pair of Pololu based stepper drivers for driving two NEMA17 stepper motors.

The laser module is cooled by heatsink and forced air (small fan) and is drived by a constant current driver.
Personally I'm using the popular NDB7875 1.6W blue laser diode (note this diode is sold as being capable of up to 3W when overdrived), but you can use your own diode (DVD recorder, BluRay, M140...).

While 3dpBurner can be controlled by mostly GRBL based applications (gcode senders), i create a pair of Windows based ones. They provides an easy control and optimized gcode streaming for the GRBL firmware and also can be used for convert images to gcode files for gray scale engravings.

BCN3D Moveo Open Source 3D Printed Robotic Arm

BCN3D presents Moveo, a fully 3d printable open source robotic arm. Another step toward fully robotic world where we puny humans will be free of any work :-)

From project description:

BCN3D Technologies keeps taking important steps in order to achieve his goal of bringing the digital manufacturing technology to everyone. In this occasion we are presenting the BCN3D Moveo, a robotic arm design from scratch and developed by our engineers in collaboration with the Departament d’Ensenyament from the Generalitat de Catalunya.
Its structure is fully printed using additive manufacturing technologies and its electronics are controlled by the software Arduino. The BCN3D Moveo has 5 axis.
Moveo, fully functional nowadays, has been born, as all the BCN3D Technologies products, with an open and educational wish.
As we have done with all our developed pordutcs, the BCN3D Moveo files will be available for everyone. Thanks to the platform Github, a website where users around the world share their designs, anyone will be able to obtain all the necessary information in order to assemble his own BCN3D Moveo at home.
Nevertheless, BCN3D will fee all the Moveo know how on our Github account, as we have been doing with all the BCN3D Technologies products. Thus, the users will be able to find the bill of material (BOM), where all the needed components for the assembling of the arm come detailed, as the CAD designs, so anyone will be able to modify the BCN3D Moveo design as they wish.
Furthermore, the Github users will find the STL files for the structure printing and the assembling, fine tuning and firmware upload manuals, which will be available both in English and Spanish.

Download the BCN3D Moveo CAD files, the STL files, the assembly and user manual and the Bill of Materials on our Github:
