Get the model
- Usually I search online to see if there are existing 3D models I can buy to use as a base. Otherwise, I use Blender or FreeCAD to design props from scratch
Plate the models
- I’ll put everything into my slicer program and set it up so that everything prints nice and strong
Start the print
- This is the easy part. Just look at the print every now and then to check if it’s failed and relax or do something else in the meantime 🙂
Remove supports/basic post-processing
- Take the print off the print plate and remove any supports attached to the print with pliers or snippers
Assemble the print
- Depending on what you like, you can sand first and then assemble, but so far I’ve always assembled before sanding
- JB Weld Plastic Bonder is my choice of adhesive for joining 3D printed parts. I try to give each glued joint an hour to dry before doing anything else
- This glue expands outwards when drying and can fill in cracks!
Sanding
Painting
- Paint the prop however you like! I use an airbrush to evenly cover everything
- Mask off areas that you don’t want to paint with painter’s tape or similar
- If you’re applying paint with a paintbrush, sometimes that might leave brush stroke marks. You can try sanding those away with 600+ grit sandpaper
Apply topcoat/varnish
- Especially important for acrylic-based paints. Acrylic paints can wash off in the rain or when in contact with water, so this will add water resistance to your paint job
Insert additional parts
- This is when I would add electronics or magnets or anything else I need to make the prop work
