How It Works

Four simple steps to a clean build plate.

Step 1 — Take a picture of the build plate
1 Take a picture of the build plate

Place your build plate on a flat, well-lit surface and shoot straight down so all four corners are clearly visible. A phone camera works perfectly — just make sure the plate fills most of the frame.

Step 2 — Mark residue with the brush or the polygon

Upload the photo and confirm the four plate corners. Then switch to the painting step: use the brush to paint freehand over dirty spots, or the polygon tool to draw precise outlines around the residue. A 2 mm safety margin is added automatically.

Step 3 — Print the 3MF file
3 Print the 3MF file

Click Generate 3MF and open the downloaded file in your slicer. Remove the reference frame object, then print directly onto the dirty plate. Use a 0.2 mm layer height and raise bed & nozzle temperature by ~10 °C for better adhesion to the residue.

Step 4 — Remove print after cooling

Let the plate cool completely. The cleanser objects bond to the residue as they print, so peeling them off takes the residue with them. If any spots remain, simply repeat the process.
