3D printing is by no means an exact science, and unfortunately requires alotof different criteria to be met in order to produce the results that areseenin YouTube videos. However, with that being said, it is certainly a loteasierthan it was only a few years ago, and there are now a variety ofproducts likethese 220x220mm PEI Sheets with 3M Tape pre-applied, which helpto improvefirst-layer adhesion and make it far easier to achieve great 3DPrintingresults. These PEI Sheets are made of Polyetherimide, a plastic polymer withimpressiveabrasive qualities, and are designed to be as thin as possible whilestillmaintaining excellent dimensional rigidity. This creates a build surfacethatnot only offers great adhesive characteristics, but will also keeptheoriginal shape without stretching or breaking from minor to moderateforces.This is a far easier method than “ABS Juice” or other Kapton Tape, asit canbe easily maintained and cleaned with isopropyl alcohol, and is capableoflasting a long time without needing any kinds of replacements or repairs. As an extra word of caution, it’s important to remember that these PEIsheetsare made from a plastic polymer, which means “ABS Juice” or any formsofacetone will damage the sheets and result in reduced printing quality.Toclean your PEI sheets effectively without damaging them, use isopropylalcoholwith a clean cloth to rub off any remaining plastic as well as any oilsthatmay have come from your hands. This will keep it in the bestpossiblecondition for continuous printing, without negatively affecting any ofyourfuture prints on those same sheets. 220x220mm PEI Sheets with 3M Tape - Technical Specifications:| – -50° to +198°C | – Ultem 1000 | – 86 Shore D | – 16500 PSI | – 0.15mm | – 3M 468P Adhesive Backing | – Natural (Light Brown/Yellow) | – 220 x 220mm Typical Applications for these 220x220mm Sheets of PEI with 3M Tape:These 220x220mm PEI (Polyetherimide) Sheets are an excellent choiceforimproving the adhesion qualities on the build surfaces on 3D Printers, andareprimarily stocked to fit the Heatbeds on the TEVO Tarantula, Anycubici3UltraBase, as well as both the Creality Ender 3 and new Creality CR-203Dprinters. However, they can be cut down to size if you have a 3D printerwitha smaller printbed, and can either be cut to size before application, orcanbe trimmed to size once the application is done. If you are still using Adhesion Aids like ABS Juice, hairspray, painterstapeor Kapton tape, but are looking for a better or more permanent solution,these220x220mm PEI Sheets are not only an effective option, but are alsorelativelyinexpensive for the value that they offer. |
