High density mesh for inverted 3D printing

A method of forming a 3D printed model comprising:

• providing an apparatus comprising:
• a vat with a photocurable ink, wherein a bottom of the vat comprises an oxygen permeable membrane;
• and
• a printing platform comprising:
• a base, and
• a mesh at a first side of the base, wherein the mesh is a mesh comprising hooks or loops for coupling the 3D printed model to the base, the mesh is a terminal element of the printing platform and an adhesion strength of the photocurable ink to the mesh is greater than an adhesion strength of the photocurable ink to the oxygen permeable membrane;
• and
• displacing the printing platform with the mesh contacting the photocurable ink from the oxygen permeable membrane to form a 3D model from the photocurable ink.
