3D printing
Printer model and programs
I am making 3d prints with Ultimaker 2 printer that belongs to Ron's group. I am using Fusion 360 to make models and Cura to slice them.
Materials and settings
The printer material comes in spools of 0.75 kg. Each spool has about ~80 meters of material.
Polycarbonate
The polycarbonate is a high temperature, strong and brittle material. The nozzle temperature is 260 deg C, and the substrate temperature is 115 deg C.
- The models crack at sharp corners in between layers (so no sharp corners).
- The models warp without a raft support.
- It's very difficult to remove supports from the small drill holes. The holes end up being deformed as well.
- 1/2 inch Thorlabs posts printed from the thorlabs models don't fit into their post holders.
- The printed parts can be machined
- If bent along the fibers, the models can take a lot of deformation without cracking
