Cooling the bit with compressed air during routing will aid chip removal and also prolong the bit's sharpness. The material can also be milled, using standard high-speed milling cutters for metal, provided the cutters have sharp edges and adequate clearance at the heel. One of the advantages of laser cutting is cleaner edges, often with no polishing or finishing necessary. Smaller items with flat surfaces can be bonded by applying the solvent along the edges via a needle applicator or syringe. For larger items, the surface area should be immersed in the solvent until the material is softened, then clamped together into position until the bond is set.
Excessive moisture can cause joint whitening.
Structural bonding of thin-gauge PETG can be accomplished with acrylic based transfer tapes. For this method, bend a small return, the width of the transfer tape, on the part to be fastened. Remove the masking and press the part into place. Another alternative is ultrasonic welding. Click here to go back to the PMF feature articles .
