Split a multi-object STL file into separate files containing each one object

slic3r --split input.stl
This will create input.stl_01.stl, input.stl_02.stl etc. in the same directory.

This worked perfectly for me on a file created with OpenSCAD containing different parts that I wanted to print individually with Cura Lulzbot Edition. I found the info here.

Settings for printing nylon on a MakerBot Cupcake + how to get prints to stick to the platform

After some trial and error I was able to reliably print parts with nylon (618 from taulman 3D) on my MakerBot Cupcake.

I used the following temperature settings:
  • Extruder: 245°C
  • Heated build platform: 60°C

I had a lot of trouble getting the prints to stick to the platform. Here is what works for me: 3M blue painter's tape, topped with a thin layer of glue from an UHU stick. I enable the "raft" option for all prints. The raft adheres very well to the blue tape covered with glue, so well that I have to replace the tape for each print.

I use ReplicatorG 0037 to control the printer and the integrated Skeinforge 35 to produce the gcode. Here is my custom profile to print Taulman 618 Nylon: SF35-cupcake-HBP-nylon.tar.gz.

Best way to clean the extruder nozzle of a 3D printer

From Isaac Budmen:

1. Heat the nozzle to 200C
2. Run Nylon filament through the extruder
3. With Nylon in the nozzle, reduce the temperature to 135C, and once there let it sit for a minute
4. Slowly but firmly work the filament out of the top of the extruder


This has worked very well for me a couple of times. Here is how the filament looks like when I take it out of the extruder (repeat steps 1-4 until it comes out clean):
