This is a simple ease of printing hack.

I often run a lot of prints, I have five 3d printers. Three FDM and two resin printers.

For the FDM printers I used to have a trade-off between great bed adhesion and print removal. I always hated banging away at my printer with a scraper.

This hack made that go away and sped up turn-around time for the next print.

Round Mirror Wedding Table Centerpieces, 10 Pieces, 10", Amazon

Glue Stick, Supermarket

Binder clips, Office Supply

Step 1: Set-up

Use the Binder Clips to clamp a mirror to the print plate.

Relevel the printer. My printer uses a multipoint touch probe, but any leveling technique will work.

Use the Glue Stick as a bed adhesive. Probably any bed adhesive would work.

Print using your normal settings.

Step 2: Secret Sauce

When print is finished, unclip the mirror, and place mirror and print in a freezer. Clip on a clean mirror and repeat, no need to wait to begin next print. If you listen closely, you may hear some crackling sounds coming from your freezer. Those are the sounds of your print detaching itself from the mirror.

The difference in thermal expansion coefficients between the print and the glass mirror makes this work, and the quick cool down helps.

Step 3: Clean-up

The mirror cleans easily with Windex or other window cleaning solution. The mirrors are cheap, but very flat, and all have a very consistent thickness, so there is no re-leveling or z adjust required when you change mirrors.

This is very simple, but effective. Enjoy.
