3D printing
Two processes. FDM for most parts, MJF for tough nylon parts. Scroll to see how each one works.
Print a fileFDM
The part is sliced into 220 layers, 0.2 mm each.
Walls, then infill.
The nozzle traces each outline, then fills the inside with a grid.
Each layer crosses the last.
The infill turns 90° every layer so the part is stiff both ways.
Layer by layer.

MJF
Many parts packed into one build. Here, the gearbox's printed parts.
Powder, ink, heat.
A thin layer of nylon powder, an inkjet pass where the part is, then a lamp fuses it. Repeat.
Cooled in the powder.
Slow cooling keeps parts flat.
No supports.
Loose powder is cleared and the parts are bead blasted grey.
