Introduction: SLA Textile 3D Print
This post is a continuation of my previous Instructable about 3D Printing pre-rolled sheets on the Formlabs Form 2 3D printer, with durable resin. Read about it here.
Instead of printing tiled surfaces, I decided to generate a regular triangular lattice, but the rest of the process is fundamentally the same.
Step 1: CAD
What you'll need:
1. Form 2
3. Grasshopper plugin
4. Intralattice plugin for grasshopper
Follow the instructions from the previous instructable. Or begin directly with the attached grasshopper script (spiral_intralattice.gh), rhino file, and STL (Lattice_textile.STL).
When you open spiral_intralattice.gh, you should find input surface 1 and 2. Model any surface, offset it, and apply both surfaces to the grasshopper file, it will then generate a latticed surface that matches the topology you made.
In my case, I modeled a simple spiral so that I could print a long roll.
The new geometry allows for thicker members (1 mm) but more pliability. Additionally, there is no post-curing involved, and instead I recommend just leaving the part to dry in the sun.
There is also no need for a support structure, since the model consists of its own triangular lattice structure.
