Identification and Mapping of Manufacturability Constraints for Extrusion-Based Additive Manufacturing

This article develops and demonstrates a set of design-focused manufacturability constraints for the fused deposition modeling/fused filament fabrication (FDM/FFF) process. These can be mapped from basic behavior process characteristics formulated in terms implicit or explicit design constraints. When FDM/FFF is explored examined its natural limitations behavior, it provide manufacturing considerations (advantages, limitations, best practices). converted into constraints, which are practical limits on ability Finally, these design–useful Many constants parameters must determined experimentally specific materials. The final list 54 major presented this work will better inform designers considering using as process, help guide decisions. After derivation presentation constraint set, extensive discussion about implementation provided at end paper, including advice determining appropriate printing parameters. three case studies implement simple problems.
