Biocompatibility and Dissolution Profile of FDM 3D Printed PETG Tablets

Individualized dose is one of the most emerging problems in the pharmaceutical sciences that can be solved with personalized medication. For the manufacturing of personalized medications we can use 3D printing which promise to manufacture complex, personalized products through a low-cost manufacturing process on-demand. 1 3D printing is an umbrella term referring to different techniques but for our experiments we used FDM (fused deposition modeling) technique because it is an off-patent, widespread and inexpensive technology.2 Polyethylene terephthalate glycol (PETG) removes the hazing effect during heating and prevents the undesirable crystallization effect that causes standard PET to become brittle during the FDM printing this is we we choose this polymer for 3D printing. 3
