Keep the filament in a dry environment when printing, and re-bake the filament if the extruded plastic contains bubbles. + +As the shim design contains fine details that need to be adhered well to the print surface, a print surface adhesion solution is highly recommended. A mixture of 70g of Polyvinylpyrrolidone (PVP) K-30 and 30g of Polyvinyl alcohol (PVA) dissoved in 500mL of 50% isopropyl alcohol makes for a good print surface adhesive. Apply the adhesive to a Polyetherimide (PEI) print surface before each print to maximize the yield of the printed shims. \ No newline at end of file
