Digital Fabric

YouMagine Community Member Vladimir Kuznetsov uploaded a wonderful design. His design “Digital Fabric” uses a really wonderful technique. He uses the Cura Pause at Height plug in to pause the print and then inserts a mesh like fabric which he fixes to the print. Then he continues the print. This lets you use regular PLA and then make flexible parts! His great idea coupled with his triangle design really makes a lot more possible. Vladimir has tried out a mosquito screen as well as nylon. Were curious to see what other materials would give great results. Many people are experimenting with fabrics and 3D printing. Usually people end up getting a result similar to chain mail that is rather limited. A lot of other 3D printed fashion is stiff and unwearable. We think that by mixing cloth and printed material Vladimir made a wonderful alternative.

Vladimir’s instructions, is to pause “when half of the part will be completed (1 mm for a part of total height of 2 mm) and to lower the buildplate for 50 mm or so. When printer will pause the printing stretch a piece of mesh-like fabric (I played with my wife’s stockings, but best results achieved with mosquito screen) and fix it with scotch tape. Unpause the printer.”

Importantly he adds, “You could make a lot with that technique, just make sure that the fabric thickness is less than the layer height.” We asked him some questions via the email and here’s how he explains his project:

“First thing I made was a small purse. I made a sexy simple polygonal design, printed two same pieces and asked one of the girls in our lab (fablab77.ru) to sew them together. She did it, but she also said that the purse is just like some Issey Miyake bag design.. so, thanks to google, I learned about trendy Japanese designer))
  
I borrowed a pair of my wife stockings and have learned that as long as the hot end does not touch the fabric, they can be used. So, I would say, any screen-like, mesh-like, net-like material is suitable, as long as it thickens is less than the thickens of one printing layer (I even thought of metals, but did not have a chance to try). Having that in mind, I found large nozzles very useful for this kind of duties. With broader (0.6 or 0.8 mm) lines large flat patterns are filling much faster, plus, thick layers (0.25…0.3 mm) are not only speeding up the printing, but make you caring less about thickness of the fabric. 
 
I also tried printing with flexible materials and it allows to create interesting results, but printing flexibles with bowden extruder and retraction enabled is.. you know.
 
Difficulties.. You have to be near the printer when half of the print is complete. Cura lets you pause the process at an exact height, but you can not leave the print overnight, to receive good results you have to unpause the printer in ten to thirty minutes, otherwise, in my experience telling the print is gonna be ruined.
It is also quite challenging to put the fabric and evenly stretch it and then fix to the build plate. Scotch tape is your number one friend. For the mosquito screen I glued pieces of velcro (the rigid half) to the perimeter of bottom side of the building plate.” 

e-NABLE Steampunk Prosthetic Hand By Jacky Wan on YouMagine

We love working with e-NABLE to help them create functional prosthetic hands using 3D printing. We really encourage anyone who has a printer or CAD skill to help them out. One of the most beautiful and completely totally over the top amazing things to come out of e-NABLE is Jacky Wan’s Steampunk hand.

Its an amazingly well designed and post processed hand and really shows what you can do with a desktop 3D printer and a lot of finely detailed work in painting and finishing it. You can download, add to, remix or print out this wonderful hand here. This is the same YouMagine community member who made the Ducati bike and light saber.

3D print is game changer in Mechatronics Competition

Students from Fontys University of applied Science in Eindhoven and Ultimaker Education have joined forces in the international Mechatronics Competition: CCM Trophee 2015. The name of the team is ‘Rembrandts’ and together we’ve achieved very good results!

Several universities from three different countries had gathered to compete in the CCM Trophee 2015 competition in Eindhoven, the Netherlands. The CCM trophee is organized every year by the Centre for Concepts in Mechatronics.

Contest regulations
All participants had to build a robot that is able to walk up the stairs, while carrying beer.  The glasses must be held in a pre described tray.  The fastest robot that spills less than 20% of the beer wins.

3D printing  brought new opportunities

3D printing brought new opportunities to the table during the design and build phase of this robot.  Also, the students of Fontys were able to save time & money in preparing some the robot parts. This unique robot has many 3D printed parts, e.g.:

  • caterpillar pulley drivetrain
  • motor cable protector&built-in encoder mount
  • triangle impact mounts on the arms
  • end-switch blocks for the arms
  • extrusion guidance and plug&play electronics
  • custom scissor lift with iGus Spindle
  • servo & gyro controlled stabilizer
  • pumptube arch – beer suction system

The result: first prize
All contributing partners are proud to announce that team Rembrandts has won the first prize!

Interested in next years tournament 2016? Please contact Ronald Scheer, Program Manager Education at Ultimaker. Or visit Centre for Concepts in Mechatronics.

Students were able to write history for their school
In recent years, students from Fontys University of applied sciences have entered this contest multiple times, but none of these teams were able to win the first prize. This year is the first year that the grand prize went to Fontys!

Thanks to all partners
This robot had not been able without the great help of:

  • AAE
  • Adruu
  • CCM
  • KMWE
  • MTA
  • STHO
  • and all the team members!

3D Printed Robots on YouMagine

In addition to Scrufie the adorable obstacle avoidance bot & the ELF AR Drone there are lots of other cool robots on YouMagine. Below we have a selection for you.
