There are a number of interesting experiments in 3D printing metal over at Lulzbot and RepRap:
A few things to keep in mind:
- Ventilation is important whenever you’re working with solder, and printing uses a lot of it
- Solder has a tendency to clog, similar to PLA but a lot more quickly
The solder tends to have a hard time with smaller diameter nozzles, but flows freely through a 1mm nozzle at 235C. It doesn’t stick to painters tape well enough to print intricate shapes, but basic ones are fine. I’m going to try printing on a raft of ABS and a sheet of copper to try for a metal octopus. Then the turbine fans
