- There are many parallels between 3D printing and Lego building in terms of creativity but a huge difference in constraints. With Lego you are limited to the parts that Lego makes and that you have in your inventory. With 3D printing there are fabrication constraints but the freedom to create smooth, curved and organic designs.
- I've decided to explore the boundary between 3D printing and Legos. Thanks to the work by Andrew Sweet (Parametric Lego bricks http://www.thingiverse.com/thing:231651) and John Stäck (Parametric Lego module http://www.thingiverse.com/thing:321848) I've been able to combine Lego bricks with a simple hemisphere in OpenSCAD. I then added pieces from the Lego Architecture Studio (http://architecture.lego.com/en-us/architecture-studio/architectural-studio-product-info) to this base to create my first design.
- This is really a proof of concept and I look forward to seeing what others do by combining 3D printing with the Lego system.
Designed in OpenSCAD, sliced in Simplify3D, and printed on a MakerBot Replicator2 with Elmer's glue stick on a glass build plate with MakerBot filament with the following settings:
Infill = 20%
Layer height = 0.2
No. shells = 4
Feedrate = 40
Travel Feed = 55
Temperature = 220C
If you want to work in OpenSCAD, you will need to put the lego.scad file in your OpenSCAD library. See the OpenSCAD file for info.
