About me

What I Make

Classes I Teach

  • None.

Classes I could be talked into teaching if there is enough explicit interest:

  • "Designing laser-cuttable model buildings for D&D, railroad, and other miniatures terrain"
  • "Introduction to pottery: Pinch pots, coil pots, and slab pots" (This may be 2 or 3 separate classes.
  • "Designing 3d printable furniture in OpenSCAD"
  • "A method for creating UV maps/textures for 3d models for use in Unity3d"


Interests

  • MAPS!
  • Laser cutting flat things and turning into 3d things
  • Visualizing strange data

Lasercut Frames

Some collected thoughts on laser-cutting picture frame

Asked in slack and on facebook:

  • Does anyone have any thoughts on finishing laser-cut picture frames?
  • I could cut multiple parts out of 1/8th" or 1/16th" material and glue together, but my real concern and question is about finishing the edges.
  • MDF or acrylic would have a clean edge, and the whole thing could be painted... but what if you were using 1/8" or 1/4" plywood?
  • Can you think of a material that would be better for picture frames?
  • How hard is it to work with a stick-on veneer?
  • What kind of paint?


Some suggestions include:

  • vinyl wrap the frame
  • "Cheaper material like Plywood could get cleaned up with some of the same techniques and materials as 3d printed parts, Water putty/spot putty to fill in voids and then sand able primer and you can get a very clean surface to paint to get the same finish as solid wood parts."
  • Another suggestion is to laser-cut a bevel using a jig. This should work if the frame pieces are thin enough and narrow enough.
  • Acrylic mirror could be really nice.
  • I love stick on veneer. I laser cut it and use it with finished plywood in layers. I just make sure to laser myself a template on the bottom layer because it’s really hard to line stuff up without it. I also like the look of veneer on top of acrylic too.
  • Otherwise I feel like a [beveled] edge is really a nice finish for frames if you have the tools. So I would probably do that then paint/stain, spray with the triple thick clear topcoat (sand in between coats) if I want the grain or maybe top it with a thin layer of resin if not. I’m kinda addicted to how easy and quick UV resin is but regular resin would be so quick if you had several to do.
  • It's not really a frame. The trapezoid shapes are glued to the back. The QR code is vinyl cut. The border is cheap 5mm lauan stained. Finished with polycrylic. Could probably glue/epoxy/adhere a border on clear acrylic.

Acrylic mirror:

  • Could make a mirror by cutting a back plate of mirrored acrylic, then acrylic cement or CA glue on some black or white strips of acrylic like this <image>. Maybe put some round or shaped holes in them so the mirror...uh... mirrors through.
  • Or could paint the black & white on using masking as a template or use a thin veneer so the mirror isn’t too shadowed
  • Acrylic frame with mirrored edges (black background) <other image>
