Abstract

Additive Manufacturing (AM) has emerged as a rapidly developing technology with applications ranging from product visualization and prototype fabrication to actual production. Various types of AM are available on the market, broadly categorized into industrial-grade and consumer-grade machines. This study focuses on consumer-grade printers, which are more affordable and widely accessible. Among these, the two most commonly used technologies are Material Extrusion (ME) and Vat Photopolymerization (VP). While the performance of ME printers has been widely investigated, comparative studies between ME and VP remain limited. This research provides a performance comparison of the two technologies. The findings indicate that VP printers outperform ME in terms of printing speed and energy efficiency. On the other hand, FDM printers offer advantages in material cost and dimensional accuracy in the Z direction. Furthermore, the study examines the potential of consumer-grade printers to support automotive product prototyping efficiently and practically.

Abstract

Additive manufacturing (AM) technologies can generally be divided into industrial-grade systems and consumer-grade machines, the latter being more cost-effective and accessible to a broader user base. Within the consumer segment, the most prevalent methods are fused deposition modelling (FDM) and LCD-based vat photopolymerization. Although FDM has been extensively studied, direct performance comparisons between material extrusion (ME) and vat photopolymerization (VP) remain relatively scarce. This study addresses this gap by evaluating the mechanical behavior of both technologies. The results show that LCD-based printing demonstrates superior performance in certain mechanical aspects (elongation), while both entry-level materials achieved comparable tensile strengths of approximately 31.5 MPa. In contrast, the flexural strength was higher in the specimens produced by ME, indicating that each process carries distinct advantages depending on the application.
