Everflex and Staymag Documentation
Disclaimer: You are responsible for making modifications to your 3D printer. Subtle Design will not be held responsible if you damage your 3D printer or any of its parts.
Disclaimer: Subtle Design is not responsible for providing a replacement Staymag sheet if you improperly align it or get air bubbles during installation. The adhesive is incredibly strong, and henceforth, is virtually impossible to pull up and realign.
Staymag is not intended to be adhered to a substrate that is able to be flexed, it is designed to be adhered to your printer's heatbed.
Step 1: Remove any build surface or prior magnet that is currently on the heatbed.
Step 2: Thoroughly remove and clean any remaining adhesive residue on the heatbed using appropriate solvent(s). Make sure to let the solvent(s) flash/evaporate fully before proceeding to the next step!
Step 3: Take the Staymag sheet and peel back a small portion of the 3M backing to reveal approximately 5mm of the adhesive. Do not peel off the entire backing!
Step 4: Line up one edge and two corners of the Staymag sheet with your heatbed and verify the position; when you are satisfied with the alignment, press down firmly. At this point, 5mm of the Staymag sheet should be adhered to the heatbed.
Step 5: Work your way down the heatbed exposing more of the adhesive slowly by simultaneously removing the 3M backing as you work down the length of the Staymag sheet.
Step 6: If any of the magnet material is extended beyond the edges of your heatbed, you can trim off the excess with a fresh utility knife.
Cleaning and Care
In the event that you need to clean the magnet sheet, only use 99% Isopropyl Alcohol! Never use water, soap, acetone, or any other solvent!
Disclaimer: Subtle Design will not be held responsible if you damage your flex plate in any way, shape, or form due to the consumable nature of the product.
We recommend using your printer in a temperature and humidity-controlled area to reduce the chances of the plate oxidizing prematurely.
Aesthetics & Discoloration
The textured, powder coated PEI option of Everflex is a handmade item and no two plates are the same.
It is normal if you see discoloration of where your fingers touch the textured PEI plate, especially when one side is always facing the bed at elevated temperatures; this occurs from skin oils reacting with the PEI. To reduce this, we recommend interacting with the PEI as little as possible and it is preferable to use fresh Nitrile gloves instead of direct skin contact.
Cleaning and Care
Being that all build surfaces are consumable in nature, Everflex is no different. However, there are some things you can do to prolong the usable life of your flex plate.
For cleaning in between prints and to remove finger oils from flexing of the plate, only use 99% Isopropyl Alcohol! Never use water, soap, acetone, or any other solvent!
When working on your printer, remember to take the flex plate off and keep it in a safe area until the work has been completed to prevent tools or other contaminants from dropping onto the surface.
Do not use scraping or prying tools to release printed parts; doing so may damage the build surface!
To release printed parts, we recommend waiting for the plate to cool down to a safe handling temperature. Generally, flexing of the plate isn't required on most prints; as the temperature of the plate cools down, you can hear the prints releasing from the textured PEI surface. For stubborn prints, you can remove the flex plate from the printer and proceed to flex opposing corners of it and the prints should pop right off.
If there are bits of leftover plastic that seem impossible to remove (support bases, etc.), resist the temptation to try to pick or scrape them out, as it is generally embedded in the crevices of the textured PEI surface. A good way to remove these bits of plastic is to start another print on top of the affected area and when the print finishes and is released from the flex plate, it usually removes it all.
Z Offset/First Layer Tuning
The first time you use Everflex, we recommend starting to print with the nozzle 100% of your first layer height above the surface of the build plate and 'baby step' the Z axis until the filament sticks 'just right'.
For example, if your first layer height is 0.2mm, we recommend starting with the nozzle set 0.2mm above the surface of the plate; this can be done using a feeler gauge. After you baby step the Z axis and find a suitable Z offset, save this to your controller's EEPROM, config file, or write it down while also noting the filament type.
We recommend users to experiment and find what works best for their printer and filament. A PID tune of the heatbed after Staymag and/or Everflex is installed can also be very beneficial. As an example, we raised the heatbed temperature 5 ºC after we installed both Staymag and Everflex on our printer and after we performed a PID tune. To learn how to perform a PID tune, please see this RepRap Wiki: https://reprap.org/wiki/PID_Tuning.
Auto Bed Leveling
Capacitive, inductive, and touched-based sensors work great with Everflex.
If you have the textured, powder coated PEI option of Everflex, you can use any type of filament that you would normally print with on a traditional solid sheet of PEI. PETG is one of our personal favorites to print with.
If you have the blank plate option of Everflex and are using a third-party build surface adhered to it, we recommend that you follow the manufacturer's list of approved filaments that work with their build surface.
