Product Details
Fits: MonoPrice Ultimate and Wanhao Duplicator
(Please see full printer list below on the 'Fits & Contents' tab)
We have developed the Wham Bam PEX Build Surface from a specially formulated polymer with a higher melt point than PEI that attracts most any filament without damaging the sheet. Prints easily pop off once cooled and flexed. This 0.35mm thick PEX build surface sheet is pre-backed with 3M adhesive and can be used as a replacement for your Flexi Plate or applied to the opposite side of your non-textured plate.
Flexi Plate sold separately.
Please note, this version has chamfered corners.

Install of the build surface:
First Use:
Make sure to rough up the PEX surface with 000 steel wool or red Composite Abrasive Pad (CAP is version 7447). On the first preparation, you will need to scuff in circles for 4-5 minutes until you have an even satin matte finish without seeing individual scratches with very little reflection. Clean repetitively with isopropyl alcohol >90% and a fresh/clean paper towel. Do not use other rags, microfiber, wipes, or towels.
If your machine has automatic bed leveling, run the leveling process and set your gap such that the first layer is well squished. For more details on achieving the right first layer squish, refer to this bed leveling guide.
If your printer uses manual leveling, follow the same guide for instructions on the leveling process.
Always read your filament spool label
Your hot end temperatures should be set within the range printed on the side of the spool of filament. The first 3 layers should be toward the lower temperature range to avoid damaging the PEX. For example, if the hot-end range is 200-230° C, start with 215°C or lower and adjust as needed for your first layer. For bed temperatures, stick with the Wham Bam recommended temperatures as shown in the chart below.
When trying a new filament
We always suggest that when changing filament types and brands or adjusting settings, always print a small test cube (or our Mini Whammy) in the far corner of your build surface. If you do not get good adhesion, you may need to adjust your settings or use glue stick to promote adhesion. If it sticks for the full print and comes off easily once cooled, you are probably good to go when printing larger parts. If it bonds too well, adjust your settings, or use glue stick. When in doubt, use glue stick as a barrier layer. PETG and some other filaments, such as ASA, stick too well and typically need a barrier layer.

After every print:
Always wait until the printed part and build plate are completely cool before flexing off and never flex when either is still warm. Never force off a print; always flex carefully once cool to remove the part.
After removing the parts always prepare the PEX for the next print by using either 000 steel wool, CAP pads, or a red Scotchbrite 7447 pad. Scuff for about 10 seconds, then clean with 90% or higher IPA and fresh paper. This will help to remove any traces of filament and prevent contaminant build up. Do not use rags, microfiber, wipes, or towels, please see here.
