This week has been full of interesting experiments. Fab Lab students had to complete the task of designing a 3D object and printing it, as well as scanning other objects.
Some of us used the Roland Modela milling machine to scan small objects with the highest possible resolution, generating point clouds with 0.05 mm resolution.
But we also tried more experimental approaches, like taking pictures of objects dipped in milk, and generating black and white gifs from them, to then generate through Fab Modules an stl file ready to print, as you can see below.
And since our lab has the full set of amazing machines, and thanks to the help of the experienced Fab Lab team, some of us were also able to scan themselves using Scannect software and a Kinect attached to a Kuka Robotic arm. The arm is a lot steadier than a human arm, therefore the models generated through it have much better detail (and require lot less post-scan cleaning in softwares like Blender or Meshlab).
Free software like 123D catch also seems to give pretty good results. It is enough to take 50 pictures of yourself from different angles to generate a 3D model!
For the printing exercise students have occupied the printers almost incessantly for 5 days. Since the BCN Fab Lab has 2 Makerbots Replicator 2, a Z corp and a brand new Formlabs printer, we were able to use various techniques to produce our 3D designs. Flexible filaments such as Ninjaflex, resin and PLA have been used.
Some of the students printed directly on textiles, some replicated finely detailed bee-wax nets, some hacked respectable sculptures uploaded by the British Museum to create transitions between faces, others replicated the spraying system of a water gun, and some took advantage of the printers to create useful tools for our Lab!
Thanks to Gabriel we will never again loose the tools for the Modela! We hope to see the file on Thingiverse soon and get lots of proud Modela owners to print their own mill tools holders!
We hope to bring you some inspiring new examples of work next week, so stay tuned!
