mesh geometry, a surface built from a series of triangles.

KEY CONSIDERATIONS
Watertight 3D models - Since the geometrical structure of the mesh geometry is com-
posed of triangles, make sure that there is no open spaces between them, or that the
them. This process is sometimes also called ‘creating a manifold model’.
Wall thickness -
its opposite sheer surface. Since the print-head nozzle has an extrusion hole of 0.4
mm, design your walls to be at least 0.8 mm thick or multiples of
wall thickness issues, so make sure your models are designed appropriately.
Warping -
of the material, warping may occur. To reduce warping, make sure that you have
applied even layers of glue on the print plate.
Overhangs - Overhangs are parts of the 3D model that extend beyond 45 degree
which is explained later.
Surface details -
3D model surfaces, it is important to know that such features will generally struggle to
clearly show through printing with FDM technology.
3D model orientation -
model orientation on the print plate. Since the printing process is through deposition of
aesthetics.
