Just stick our magnet to your bed and slap the flex plate on to the magnet. Start your print like you always do and then when the bed cools (40C or less) you can pop the plate off with our convenient lift tabs and then flex the part off. You’ll love using our plates and if you want even more adhesion than the PEI offers add our EZMat to the rear of the plate for easy printing of other filaments (like ABS, ASA, or Nylon) that require higher temperatures (enclosure required for some filaments).
Maintenance Tip – Make sure to clean your bed before applying the magnet and occasionally wipe down the plate with IPA to keep the surface free of oils for best adhesion.
Smooth plates shipped after 4/2021 will NOT have a protective film on them.
Adhesion Help – Check out our article here: EZMat/EZPei – Adhesion Tips and Tricks
ABS – You will need to use something like VisionMiner Nano Polymer to stick ABS to PEI, or use our EZMat on the other side of the plate. Smaller parts will stick but larger parts may lift without an adhesion promoter on the PEI surface
PETG/PCTG/TPU – If you are not careful with your 1st layer you can risk bonding the PETG/PCTG/TPU to the PEI surface. This will damage the surface. To prevent damage to the surface apply hairspray or PVA gluestick before printing PETG/PCTG/TPU on the PEI or EZMat surfaces
Part Removal – Make sure your plate is at close to room temp (under 30C) before removing parts. If you remove it when hot it is more likely to damage the surface.
Magnetic Base Compatibility – Using our plates with a 3rd party magnet may result in the plate warping as other brands’ magnets are not as strong as ours.
Maintain Proper Z Height – When starting a print make sure your bed is level and your nozzle is not too close to the bed (if using an ABL system check that your Z offset is correct and use the Babystepping to adjust during a print). Running the nozzle too close will damage the surface and/or embed the plastic into the sheet. Damage due to improper Z height is hard to fix and is not covered under warranty.
Cleaning – Keep the top and bottom of the plate clean as well as the magnet if you get anything on it. IPA is what is recommended to clean the plate and magnetic base. Make sure that no liquids or adhesives are on top of the magnet or bottom of the plate. If liquids are between the magnet and the plate it can damage and degrade the magnet so keep them dry and clean.
Dual Side Usage – When using the EZMat or other surface on the rear of the plate the magnetic strength will feel less than using a plate with only the PEI surface. We have tested using dual sided applications on our plates in house and they work well even with a surface on both sides. Some users have reported that on large prints having another surface on the rear can cause it to pull up from the magnet. Only apply a 2nd surface to the rear of the plate if you accept this risk.
Be sure to check your bed size. TH3D is not responsible for the wrong size ordered and/or errors in the listings. We try do our best to keep descriptions up to date but some manufacturers make changes to machines after release.
- PLA – 60C
- HTPLA – 60C
- PETG – 70-80C
- PCTG – 70-80C
- ABS – 100C
Please note that all PEI surfaces are pre-installed on the plates so you will not have to install them yourself. If you purchased the EZMat as well apply this to the side of the plate without the logo on it.
All plates and magnets are inspected to ensure full functionality to make sure they meet our standards for them. We only ship out plates that meet our QC standards.
Smooth PEI plates – These may have a non-uniform appearance under the PEI as that is the adhesive visible through the PEI sheet, this is normal. Additionally, the Smooth PEI plates may have small, cosmetic marks that do not affect functionality from manufacturing and handling.
Textured PEI plates – These may have a non-uniform color appearance as they are sprayed and the PEI is baked onto the plate, this is normal.
Textured plates will have the texture covering the print area for the machines they fit (example: CR-10 has a 310×310 bed but print area is only 300×300).
Plates will not be exchanged if they are in these specifications. Only if a plate has a defect that affects it’s functionality will be considered defective.
Why are there some variances in appearance with the plates?
They are all sprayed (textured) or applied by hand (smooth). It is impossible (even with a machine) to make every single plate identical. The information provided above is so you know what to expect from the plates
3 Months Warranty - Our warranty covers any and all defects with the product. If your product fails or has problems within the warranty period you can contact our support team by using the Contact Us link.
Damage/Failure due to improper installation, improper usage, failure resulting from an issue with the machine the product is installed on, 3rd party products connected to our product, and/or modification of the product are not covered under warranty.
Return/Refund Information for Flex Plates and Magnets
Once a magnet is installed on a printer it is NON-REFUNDABLE as there is no way to remove it from the bed without damaging it.
Flex plates can only be returned if they are in like-new condition and have no signs of use on their surface.
John (verified owner) –
I was really happy to receive the Smooth PEI surface sheet – especially to finally have a flexible sheet on my Ender 3!
My first few prints on this sheet were GREAT – no issues whatsoever! Prints stuck well, but came off nicely afterward with a quick flex of the plate. This worked especially well when the plate was cool.
However, after about 20 or so prints, the surface seemed to … deteriorate I guess? The surface was still very “sticky” for prints, meaning that they stuck well to it. However, they started to become more and more difficult to remove. No amount of cleaning with alcohol or even soap & water seemed to restore the sheet.
When compared to the flexible steel sheets from – for example – Prusa, this is an inferior sheet.
Still, the price difference plus the fast shipping and support from TH3D (located in the US) is a plus so that’s certainly worth something. For those reasons, I still went with this sheet rather than the Prusa, not to mention it’s made to fit my Ender 3!
