3D Printer Enclosure: Fabrication

January 2, 2015 Experiments

With the 3D printer enclosure design complete, it was time to build!  The enclosure walls were made from 3/4″ MDF for increased sound damping.  It also happens to be super cheap and easy to work with.

  • My new workshop in my garage.

With the main walls assembled, I then took some time to create a nice 1/2″ radius  fillets on each corner joint.

  • First, I drew lines as guides for an even chamfer that was tangent to the fillet I wanted. I got these line dimensions from my Solidworks model.

Because I am a terrible carpenter, there were a lot of uneven joint seams.  The next step was to even out these surfaces, and then seal and sand the MDF for painting.

  • I probably wouldn’t recommend this stuff for use on wood that you’re going to clear coat… but it works great for things you’re going to paint.

The next task was to drill some holes for filament, and the cabling.

  • A 3/8″ hole for filament up top.

I painted the exterior with satin white spray paint and then cut some 1/4″ polycarbonate to size, sanding the edges to remove material until it fit perfectly.

  • The exterior is a gloss white.

Next, I measured and cut the baltic birch plywood to size and rounded the corners for a consistent 3/8″ offset from the white MDF piece.

  • I made rough cuts with a jig saw.

After sealing, sanding, and using glossy spray shellac to finish the wood, I attached the panels to the white enclosure body with dowels and glue.

  • Drilled 1/4″ holes for dowels.

With the enclosure fabrication complete, the next step was to design some 3D printed components to finish out the enclosure!  Take a look at the next installment here.
