Wham Bam PEX User manual

Bambu Lab X1 258 x 258 v1
Thank you for purchasing a Pre-Installed Wham Bam PEX for the Bambu Lab X1 and
P1P.
You are going to love this system!
Included:
1 PEX Build Surface or mounted to a Flexi Plate
Sheet Build Surface mounted to a Spring Steel Flexi Build Plate with high temperature 3M
adhesive.
5 ArUco Code Stickers for High Temp Plate
Set of 5 stickers to add to your Flexi Plate for the X1 to recognize it as a High Temp Plate.
(these stickers are only needed for the X1 with Lidar)
Mounting Instructions:
1. REMOVE protective film from the top of the PEX Build Surface.
2. Prepare the PEX Build Surface sheet surface using 000 steel wool or a fine
Scotchbrite pad and a bit of isopropyl alcohol (common high percentage rubbing
alcohol from your pharmacy is fine). Then clean the surface repetitively with fresh paper
towel and alcohol.
3. Apply one ArUco Code Sticker to the front left tab of the Flexi Plate inside of the
etched box. Orientation is not important.
Should your sticker ever get damaged, keep the other 4 on hand to replace as needed.
4. You are ready lay the Flexi Plate onto the magnetic bed and begin printing!
Use:
You may have to heat your bed higher than previous temperatures, do a bit of testing to
find your best bed temps with PEX. Our PEX Build Surface is specially formulated to
resist much higher temps than any PC build surface. It has great physical bond to the
parts without them ever melting into the surface.
After printing you can lift the Flexi Plate by the handles and remove and set somewhere to
cool.
Once both Flexi Plate and parts are completely cool just bend the Flexi Plate on one axis,
then on the other. Large parts should just pop right off. Smaller parts may need a bit
more bending or slight help with a spatula. Never dig into the surface if you can help it.

Maintenance:
After every print we suggest wiping with isopropyl alcohol and fresh paper towel, or even
better, quickly scuff and clean with 000 Steel Wool and alcohol and paper towel before
reusing. This will prevent contaminants from the filaments from building up.
Should the PEX ever loose its grip, use some Acetone and steel wool to remove any
residue that may have permeated the PEX top layer. You may also try common dish
detergent or vinegar and clean with water as these help break fats added to filaments with
effects.
Suggested Temperatures and Settings for the Bambu Lab X1:
Filament Bed Temp °C Hot End °C
PLA 60-65 190-220
* PETG 50 240-250
ABS/ASA 110 230-250
* For PETG there is a molecular similarity with PEX and PEI, Bambu sets their default temp settings
way too high in order to achieve faster prints, you need to be more careful with settings on PETG
and lower these.
Also never pry parts off, wait for the plate and the part to fully cool and flex off to remove.
Test all PETG on a small area, each are different, if you get bonding use some glue stick to create
a barrier layer. For a comprehensive explanation see pdf (found on Wham Bam Systems Support
