We start with our original 0.4mm high chromium spring steel Flexi Plates, powder paint them with Ultem brand PEI coating, and bake them in a kiln. The PEI Powder Painted Flexi Sheets have a pronounced texture and give the bottom of your part a fantastic finish! The plates are coated on both sides, so you can save one side for pristine parts while you abuse the other side. Works perfectly with your Wham Bam magnetic base, not included. The Flexi Plate is 0.6mm thick once coated with PEI.
It behaves as most PEI sheets would and works great with PLA, TPU, PETG, ABS, as well as many other filaments. If you need more adhesion for tough-to-stick filaments like Nylon, feel free to use purple glue sticks or Magigoo, they will wash off with water after use.
To clean, use some isopropyl alcohol after each use to keep contaminants away. If you ever need to restore adhesion, use very fine sandpaper 600 or higher and pass lightly, then clean with alcohol. For PLA and PETG we recommend 70° C bed temperature.
*Attention: It is the buyer’s responsibility to be sure the size selected will work on your machine. Measure your bed, do not rely on build volume. Wham Bam is not responsible for mistaken order sizes.
**It is the buyer’s responsibility to pay any taxes and import duties. No refunds of uncollected customs packages.
This has been a great upgrade to our Phrozen Sonic Mighty 8K (now upgraded to 12K). It is so strong, much stronger than the generic mag plates from other manufacturers. Make sure to not fill resin past the max line on the resin vat, as adding the mag plate will add thickness and therefore displace more resin, and you don't want to overflow.
I have 2, one on each of my X1C's. I have a P1P that doesn't get used much only because I need to get another WB for it. This is by far the best build surface I've used. Everything sticks, perfect first layers all the time, and I can get through 4 day prints without ever having to worry about any part of the print coming loose. I print all PLA at 62C on these and never have any issues.
