TABLE OF CONTENTS



1. REMEMBER TO REMOVE a THIN PROTECTION FILM ON GOLDEN SMOOTH PEI BEFORE PRINTING.*

2. Re-Adjust your bed level, and re-run you bed mesh and calibrate your z-offset if you have ABL system. As incorrectly setting the first layer offsets can result printed part sticking too well to the PEI coating and if care is not taken (letting temperature drop to room temperature before removing  the part) it can damage the PEI texture layer. If it set too close, the printer nozzle can also cause damage to the print surface.

3. Remember when printing between different materials, re-adjust your probe off-set if you're using fixed Z or probe mount. Printers with nozzle probe such Voron Tap/CR6 SE can re-home z when bed reach to temperature to ensure accurate z off-set. 


Part Removal - Ensure that your plate is nearly at room temperature prior to removing any components. Removing them while the plate is hot increases the risk of surface damage. Ensure you wear safety gloves when removing part using a scraper as both the build plate and cutter can cause cut due to thin edges of build plate. 


Magnet Application - Ensure the build platform is clean, you can clean with surface with IPA, also clean the sticker magnet so dust does not get transfer when un-peeling magnet adhesive.


* Note: Its a thin clear protective film on the applied smooth PEI film. You can either use some alcohol or water to loosen up the plastic. Ensure you're not actually peeling thicker smooth PEI underneath the thin protective film from the build plate. More Info Here

Texture/Frosted Bed Side - Golden/Black Editions

          Product batch texture variance: The exact color depicted in the online store and our knowledge base may differ from yours. All sheets are checked and verified being within tight specifications. These specifications are both considering the manufacturing method and the sheet's function (adhesion and durability used with certain material types), but not the cosmetic aspect of the sheet or pattern left on printed parts. We can not guarantee the pattern left on your printed objects will match perfectly from sheet to sheet. 

            

Main attributes

  • Textured finish designed specifically for easy removal of printed objects from the print surface
  • Ideal for extensive printing of PETG, PLA, PC, CPE, PVA/BVOH, HIPS, Flex, nGen, Nylon, ABS, ASA.
  • No need for glue stick with flexible filaments (TPU/TPEE)
  • Prints automatically detach after the sheet cools down
  • To be cleaned with ~90% IPA or deneutered alcohol when cold. Do not use anything made for skin! It can contain oils/sugars that ruin adhesion!


Do:

  • Print without any adhesive or separation layers when possible
  • Print supported materials (PETG, PLA, PC, CPE, PVA/BVOH, HIPS, Flex, nGen, Nylon)
  • Remove prints after the cooldown
  • Bend the sheet to remove printed objects


Considerations

  • Prints from ASA, ABS, Nylon and PC Blend may require the application of a glue stick (separation layer). Ensure squish is not much to prevent difficulty removing skirt/brim. In our print farm, DREMC and Polymaker filament shouldn't require separation layer but can result is quicker wear of the PEI. Some ABS+ will blend PETG/PLA with ABS to improve printablity but can cause too much adhesion. See Functional Printing, specifically Ellis Guide for detail of the first layer, you should still able to see layer extrusion line.
  • Avoid stopping print at first layer, for allow easier part removal as single layer print can be difficult to remove without using a tool such as plastic scraper or smooth edges which can damaged textured PEI.
  • Not scratch-resistant!!! Do not use metal spatulas etc. to remove the prints. We recommend printing a plastic spatula, like this one.
  • Live Z value needs to be readjusted if you switch sheets.
  • Small PLA may require a brim or brim ears for sharp corners.


Don’t:

  • Use acetone and other agents
  • Remove printed objects before cooldown
  • Use any instruments (spatula) to remove the printed object, We recommend printing a plastic spatula, like this one


Maintenance

  • Clean with ~90% IPA (isopropyl alcohol) or denatured alcohol when cold. Apply on unscented paper towel and rub the sheet down. Do not use anything made for skin! It can contain oils that ruin adhesion!(You don't need to clean between each print, unless you notice filament/dust build up)


If your print surface is perfectly clean and all grease has been removed by wiping it with a paper towel soaked in isopropyl alcohol ~90%. Also, make sure the first layer height is set up perfectly.


If your prints still do not adhere reliably to the print surface, try to wash the sheet in warm water with a few drops of liquid dish soap (not hand soap). This can clean away oils that are not affected by rubbing alcohol. However, the textured sheet is not water-proof so consider this a last resort which should not be done often.



Some entry levels printers such as the poplars ender series and it i3 clones usually have a thin aluminum bed surface which tends to have warping issues. Please preform another manual bed leveling after installing new magnetic or run another Bed mesh if you don't have set to probe mesh at start new print. If you don't have ABL system and find your bed to be warping only a little bit, a ABL could help but if you find the bed have major warping issue you should option such as less prone to be effected by bed warp like glass. You would always install your PEI on top of glass using clips.






Smooth Bed Side - Golden/Black Editions

            

Main attributes

  • Ideal for printing PLA, HIPS, ABS/ASA, composite materials (metal/wood).
  • Prints with sharp corners or a small first-layer area are less likely to detach.
  • Scratch-resistant. Can be used with a metal spatula, however, cosmetic scratches may appear.
  • Compatible with most types of filament.
  • Little to no surface preparation, (other than cleaning).
  • Clean with ~90% Isopropyl alcohol (IPA) or denatured alcohol.
  • Can be cleaned with acetone, but do not overuse it (1-2 times per month).


ABS – You may need to use something like Magigoo to stick ABS to Smooth PEI, Smaller parts/flat parts may stick too well and cause difficultly in part removal.


PC/PETG/PCTG/TPU - Carelessness with the initial layer can lead to PETG/PCTG/TPU bonding to the smooth PEI surface, resulting in surface damage. To avoid such damage, apply hairspray or PVA gluestick or Magigoo before printing PETG/PCTG/TPU on smooth PEI. 


Do:

Degrease the sheet with isopropyl alcohol (IPA) 90%+ with fine microfiber cloth

Remove prints after the cooldown

Bend the sheet to remove printed objects when cooled

Must use protective bed adhesion barrier such as Glue Stick with PETG, PC


Don’t:

Use acetone and other similar stronger agents

Remove printed objects before cooldown



Considerations

  • Live Z value needs to be readjusted if you switch sheet-type. 
  • Some filaments, like PETG, ASA, ABS and PC Blend, TPU may need a protective separation layer, like gluestick applied thinly before printing!
  • Keep the sheet clean! Any grease will greatly reduce adhesion.

Maintenance

  • Clean with ~90% IPA (isopropyl alcohol) or denatured alcohol when cold. Apply on unscented paper towel and rub the sheet down. Do not use anything made for skin! It can contain oils that ruin adhesion! (You don't need to clean between each print, unless you notice filament/dust build up on smooth PEI)
  • 1-2 times a month it can be cleaned the same way with acetone if IPA cleaning is not sufficient.
  • After extended use (1-2 years) the surface can smooth out further, which affects adhesion. Using high-grit sandpaper (600-1000), the PEI can be revived by light sanding, bring fresh PEI to the surface. The sheet will have a very light texture after this treatment.
  • The smooth PEI film on the steel sheet can be replaced in case of extensive damage.

If your print surface is perfectly clean and all grease has been removed by wiping it with a paper towel soaked in isopropyl alcohol 90% and if the first layer height is set up perfectly, yet your print still does not adhere reliably to the print surface.


Bubble under the PEI

Over time, you might see some small bubbles underneath the PEI. This is nothing serious. These bubbles usually do not affect print quality and will disappear after a few days or weeks. Here are 2 tips that will make these bubbles disappear faster:

  1. Swap the side of the steel sheet you were printing on. This will speed up the "recovery" of the PEI surface.
    Bubbles appear around the spot where you print the most (center of the sheet), most often underneath the corners of your printed parts.
  2. When slicing the models, vary your placement on the print surface. Don't use just one spot i.e. the center.


Dent/Bubble on smooth PEI

Sometimes, there might be a small dimple or dent in the smooth PEI layer when you first unpack the steel sheet. Don't worry, just flip the sheet over and use the other side. Thanks to the heat of the heatbed, the dent will disappear by itself after some time (about 1-2 days of print time).



Note:

PEI sheets (smooth, textured, etc.) are not covered by warranty as the coatings are designed to diminish over time unless failure has occurred due to a defect in materials or workmanship. Cosmetic damage, including but not limited to scratches, dents, cracks or other cosmetic damage is also not covered by the warranty. Only defective sheets on arrival are covered by warranty. Tiny dots may appear on the PEI-Ultem surface. These can slightly affect the finished print bottom surface. However, they do not impact the printing process, reliability in any way. We do not consider these dots a reason for a warranty claim.




Satin Textured Black Editions


The Satin sheet sits between the smooth and textured variants. Its fine powder-coated surface with a lightly textured matte finish offers an optimal level of adhesion, especially when printing PLA/ABS/ASA/PETG materials. It is fully compatible with a wide range of common and less-common filaments, such as Polycarbonate (PC), TPU with some additional glue barrier.


For Bambu Slicer (You can use Smooth PEI or Textured as build type on the satin). We recommend textured PEI print setting temperature for most case. For ABS/ASA, most filament should self release after cool, for PLA/PETG you may require to flex bed once the bed has cooled.

If you're switching from Smooth or Textured you will need adjust z offset to suit based on filament.


Do:

Degrease the sheet with isopropyl alcohol (IPA) 90%+ with fine microfiber cloth

Remove prints after the cooldown

Bend the sheet to remove printed objects when cooled

Must use protective bed adhesion barrier such as Glue Stick with TPU or extensive printing with PC/PETG or you may notice quicker wear on the build plate.


Don’t:

Use acetone and other similar stronger agents

Remove printed objects before cooldown


Considerations

  • Live Z value needs to be readjusted if you switch sheet-type.
  • Not suitable for Voron Tap R8
  • Small footprint PLA print may require brim
  • Keep the sheet clean! Any grease will greatly reduce adhesion.
  • Applied protective barrier when printing TPU/TPEE
  • PC ABS/ASA may require build adhesive or brim for larger print.
  • If you're printing extensive PC Blends such as PC ABS/PC CF we have found using protective separation layer extend life the build plate.


Printing FAQ

First Layer (Texture/Frosted/Smooth Build Plate)


Ensure you have re-calibrate your z off set if you using Bl Touch/CR touch, Klicky Probe. Please note, improper first layer adjustment can lead to damaged of the build plate surface. It is true the texture require lower nozzle off-set compare to smooth or glass build surfaces but it important not to overdo it. Please see attached example, actual z off set may vary depending on your printer. If you still having issues with print not sticking, please refer to above maintenance/cleaning. For small parts, we recommended printing with brim, as it does make part removable easier. It can also aids is some warp for sharp angle/corners prints.


Example 1 (Texture/Satin):

Example 2 (Texture/Satin):

  • The lines will not be as visible as on a smooth build surface. 
    • Note: this doesn’t mean they should be invisible.

Bottom View: #3 or #4 is desire, but in end it up to personal preference and you may need adjust z-offset flow depending on filament/colour.

Example 3 (Smooth)

  • You should not have any gaps between the lines like #1 or line are fading #5.
  • You should still be able to clearly see the lines at the center. They should not be fading or invisible. 
    • It’s normal for the lines to fade a bit near the edges/corners.
  • NOTE: Upon review, somewhere between square #3 and #4 is closer to ideal.

Remove Protective Layer

Thin Clear Protective Layer, as shown below. 


* Note: Its a thin clear protective film on the applied smooth PEI film. You can either use some alcohol or water to loosen up the plastic. Ensure you're not actually peeling thicker smooth PEI underneath the thin protective film from the build plate.
