Our XTR Flexi Plate is an extra thick spring steel, made with the same high quality, rustproof chromium alloy as our FBSR, providing extra stiffness to resist peeling and bending when printing edge to edge.

Sanding The Flexi Plate for more grip:
You can scuff one side of the Flexi Plate with 400 grit wet dry sandpaper (and clean well with IPA and the fresh paper towel a few times until the paper towel comes away clean) to get more grip.
Need Even More Grip? Try this tip:
If even more grip is needed use 320 or even 220 grit. Keep one side with our original etched surface and the other sanded, you can flip over as needed.
Resin Printing Best Practices with the Wham Bam Flexible Build System
You can wash parts on the Flexi Plate
You can wash parts on the Flexi Plate or remove them from the Flexi Plate and wash parts separately.
Never cure on your Flexi Plate
Never cure parts on the plate to avoid depositing cured resin on the Flexi Plate.
Never leave resin between Flexi Plate and Magnetic Base
Do not leave your Flexi Plate on the Magnetic Base with resin between the two for longer than 2 hours.
Stuck Parts
Large rigid parts will pop off when you flex the Flexi Plate, but smaller supports may stick. For stubborn areas, carefully scrape with a spatula, chisel, or razor blade. If necessary, retouch the surface with 400-grit sandpaper.
Always clean your Flexi Plate & Magnetic Base between Prints
Always clean your Flexi Plate well with isopropyl alcohol and let it dry completely before placing it on the Magnetic Base.
Always Clean your Magnetic Base with isopropyl alcohol and let dry completely before replacing the Flexi Plate.

Solved a ton of time scaping models off! I bought two so one can be draining and the other can start printing. Did need to scuff them up a bit to get models to stick
Bought this for an Elegoo Saturn 4 ultra, has to be the best thing I did. Very easy to install and performance is superb. Handles a full build plate in my scenarios and outside of now being able to print high detail small parts flat on a build plate, without destroying them in the removal process… I also save a tremendous amount of resin as the build plate keeps the upper portion completely out of the vat.
Will buy this for any resin printer, I consider this a must have now.
I have not received the order yet after more than 90 days
We are sorry to hear about your issue.
It seems the package was sent, arrived all the way to Pescheria Borromeo, but was returned, not sure why this happened.
I am having Cesar our CS manager look into this and get back to you
We will resolve this asap and get back to you
It is not clear or obvious on the website that you need to buy the magnet as well, so I have no idea how well it works. I would be willing to change this review if they rectify this.
Hello Colin,
Sorry to read your frustrations.
Believe me, all over the website we make sure to indicate that you should purchase a magnet if you need one.
here is a link to a few screenshots https://cdn.shopify.com/s/files/1/0016/6179/6450/files/magnet_warning.jpg?v=1782329572. Please see for yourself.
I am here to help you if you want more information.
Extremely difficult to remove the build platen because of magnetic forces. I have asked Wham Bam for help but no solutions forthcoming.
Hello Herman,
This is Peter, founder of Wham Bam Systems.
Sorry for your disappointment and issues.
I see my technical support person Oscar had been communicating with you and asked you a question to better help you, but did not receive an answer.
Let me try to help you with your issue.
Magnetic Forces
If your forces are too great when trying to remove the magnet there are a few possible reasons and solutions.
Our XTR Magnets are very strong intentionally to resist the suction forces caused by the machine.
Magnets are very effective in forces perpendicular to the surface but not in peel or sheer, buy flexing the Flexi Plate up in one corner you can relieve the magnetic attraction and release the plate.
Most likely:
When you are printing a full bed plate or very large print, the part will not allow the plate to flex and thus it is very difficult to remove.
Questions:
Does this hard force happen when printing smaller parts?
Are you removing the full build head after a print to remove the Flexi Plate and Part?
Solutions:
1. Remove the full build head and place on the table and try to flex the tab of the Flexi Plate up, this should help to relieve the tension and release the magnetic grip.
2. If your Part is very large - consider printing on supports rather than flat on base, the supports will allow a flexible area under the part to give the Flexi Plate more flex and be much easier to remove
3. Ensure that there is no resin between the Magnet and the Flexi Plate, clean well after prints, and reassemble only when dry.
If you can give me a bit more information I can help you to get the most out of this machine
Thank you!
my best,
Peter
