Tutorial: How to Cut Up Large Files for Small Print Beds

Picture this… you’re super pumped about that new STL you just downloaded. Maybe it’s a studio scale Galactica, or better yet, some Stormtrooper armor. You open up the files and bring them into your slicer of choice only to find out that BAM, the file as a whole doesn’t fit on your print bed.

Womp womp womp.

Don’t worry! Check out the video above or follow the instructions below and you’ll be on your way to printing big things on your little printer (it’s nothing to be ashamed of).

Instructions

These are instructions for the Mac version of Meshmixer – sorry, I’m not a PC guy.

  1. Download Meshmixer here: http://www.meshmixer.com/download.html
  2. Open your oversized STL
  3. Click the “Edit” Icon in the left nav (on a Mac)… (it looks like the Death Star)
  4. Select “Plane Cut”
  5. At this point the plane will overlay your object, move it to wherever you want to get the cut you want to achieve.
  6. In the overlay, set “Cut Type” to “Keep Both” (so you can keep both objects in the space.
  7. Leave “Fill Type” as is
  8. Click “Accept”
  9. Now you may not see anything but I assure you the cut happened. Since the cut happens at 0 (think of the kerf of a saw blade that is literally as thin as air) you won’t see anything until you separate the shells.
  10. Repeat steps 4 – 8 until you’re satisfied.
  11. Click on “Separate Shells” in the left nav.
  12. In the “Object Browser” you’ll see all your shells.
  13. Select one.
  14. Click on File
  15. Click on Export
  16. Save wherever you need to!
  17. Repeat Steps 11 – 16 until you’re done.

Boom, you’re good to go!
