Abstract Scope |
Design guidelines for material extrusion (MEX) of polymers in additive manufacturing (AM) are much more common and developed than those for ceramic AM. The similarities and differences between the properties of these two materials and their extrusion processes are discussed, specifically in viscosity and extrusion and solidification methods. Experimental measurements of some geometric limits for the Ceramic On-Demand Extrusion (CODE) process are described and compared to the limits found in the ASTM F3529-21 standard for MEX-Polymers. A number of guidelines for CODE and similar ceramic AM processes are generated and demonstrated, such as the removal of supports, increase in particle migration for fully enclosed cavities, and gap-spanning differences. Altogether, this provides groundwork and identifies future opportunities for development for design rules for MEX-Ceramics. |
