Fits: Phrozen Sonic Mighty 8K

Introducing the XTR, the most powerful version of the Flexible Build System for Resin on the market. This eXTReme line is designed for larger, more demanding resin 3D prints to ensure that even the largest prints stay securely in place. XTR is the ultimate solution for superior performance and reliability in resin printing.

Our XTR kit features an extra thick spring steel Flexi Plate, 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. The Wham Bam Flexi Plate is custom-etched on both sides to provide an exceptional grip for your first layer.

The accompanying Magnetic Base is an extra thick, custom-designed composite magnet with alternating polarity, boasting an incredible strength of over 800 Gauss. It is backed with a specialty 3M adhesive designed to resist harsh solvents and chemicals, for a permanent bond.

Get everything you need to install in the Flexible Build System or upgrade to the Double Wham kit, which includes an additional Flexi Plate. This extra plate enables a continuous printing workflow by allowing you to start a new print on your 2nd plate while starting the cleaning process on your recently finished print, significantly increasing your productivity.

Ideal for both beginners and seasoned professionals, the Flexible Build System for Resin is a game-changer, offering a seamless, efficient, and reliable solution to your resin 3D printing needs.

Printer Fits:
• Phrozen Sonic Mighty 8K

*Attention: The Mighty 8K build plates have a 1 mm variation on both X and Y and since we do not recommend overhang, we produced the smaller of the two. This will not affect your build volume and we recommend mounting it in the center of the build plate.

Do you have a printer similar to what's listed under Printer Fits or May Fit?
If you have a printer similar to the one described above and believe our solution could work for your printer, please follow our easy instructions on measuring your build plate. Let us know if your printer matches our specifications or is even close! We’d love to hear about it, and you might even receive a discount on Wham Bam® merchandise for your efforts.

Do I need a Z Spacer?


It is possible to use our system without installing spacers, but to confirm you need to see if when in current level condition you have at least 3mms more upward movement on the head (if installing our FBSR) and 4mms (if installing an XTR).

Note: It is always safer to use a spacer if we have one listed.

We always recommend sanding the build plate (Textured & non-textured) to open the pores, even for brand-new build heads, to help remove cutting oils and contaminants and prepare the metal for the 3M bond.

We worked with 3M to have the best glue that would resist the harsh chemicals found in 3D Print Resins and Isopropyl Alcohol, but it does not do well on any metal with contaminants.

On top of it all, many printers are famous for not having a flat bottom, which will cause issues later.


Follow this video or see the instructions below for the installation of the Magnetic Base:

  1. Be sure to remove the old Magnetic Base and adhesive
  2. Check that your build plate is flat by laying a steel ruler on the edge across it in all directions and see if there is any light passing between it.
  3. Let the whole head sit for at least 30 minutes in an alcohol bath to remove residue from the entire build head and hard-to-reach places.
  4. Clean every surface of the build head well with pure isopropyl alcohol and a paper towel to remove all residue and dry well.
  5. Use 220-grit sandpaper on the bottom of your build plate to rough up the surface and open the pores and ensure there is no residue left
  6. Re-clean with alcohol and a fresh paper towel, repeat the process with a new paper towel until the towel comes away clean
  7. Let dry completely
  8. Then mount the Magnetic Base and leave it to cure for 72 hours.

Bed Leveling for Resin Printers with a Flexible Build System Step-by-Step Guide.

Please see this video for a visual explanation of the leveling process.


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.

Great for convenience but does have some design flaws

I love the idea behind this product and I do feel the quality is generally good and introduces a lot of convenience, however the flexible plate is not pretreated in a way that helps prints to stick to it well and so I did have to rough it up quite a bit regardless of my resin settings. The big problem however is the adhesive used which just didn't do its job properly, after roughing up my build plate and sticking down the magnet and leaving to set in place with added weight, the system worked fine until I tried to print a large object with high surface area. This caused the magnet to be ripped off of the plate which apparently others have reported, so please be aware of these potential problems when you consider buying this product. I am giving it a three star because frankly not often should anyone print something flat on the plate, in this case this was actually a test print which needed to be printed without supports.

Thank you for your purchase and review. We are sorry to hear you had this issue, the magnet should be able to withstand the force even in the situation that you describe. Please reach out to our technical support team at technical@whambamsystems.com and they can help!

Completely changed the printer. So much better.

I wouldn't buy the printer again without getting this plate. Huge improvement. Thank you!

Great upgrade!

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.

Wham Bam Magnetic System is a Must for Resin

The Wham Bam system makes my life so much easier... working with the Mighty 8K was cumbersome considering you have to separate and handle the quite large build plate from the printer every single print, and also because of the textured surface that guarantees an enormous amount of adhesion it was sometimes really hard to separate the object from the plate. Now literally takes me a minute or less to separate the metal sheet, pop-off the prints and install a fresh sheet (I use two of them). Also the process is a lot cleaner that before.

237 x 127 - XRT

The XRT plate is slightly thicker than the other; made for larger prints. I was able to print table top figures with no issues however.

The fit to the Mighty 8K was perfect (slightly smaller than the build plate). An arm extension is needed and can be found on Cults.

Overall, great quality and amazing product... Exactly what you would expect from Wham Bam.
