Blue Manganese Blank Spring Steel Sheets
Couldn't load pickup availability
Blank blue manganese spring-steel flex sheets for small-format 3D printer beds. Choose 120, 150, or 160 mm to match your build plate, then add the PEI, PEX, G10/FR4, or other build surface you actually want.
Why use a blank sheet?
- No factory PEI coating: start with a bare sheet for adhesive PEI, PEX, Garolite, specialty films, or your own test surface.
- Flexible spring steel: use it on a compatible magnetic bed, then lift and flex the sheet for easier part release.
- Blue-finished surface: an unbranded dark-blue spring-steel sheet like the one shown in the photos.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
