Abstract

Rapid prototyping is a group of techniques used to quickly scale physical parts or assemblies using three-dimensional computer-aided design (CAD) data. The process of 3D printing constructs three-dimensional objects from CAD models, usually by adding layers by a layer of material in a row. Therefore it is also called making addictive manufacturing. Along with the development of rapid prototyping, there are many choices of materials on the market to make parts of 3D printing. The material can be in the solid filament, liquid resin, or powder. Solid filament FDM technology material is the most commonly used by industry ? these materials such as ABS, PLA, PETG, HIPS, and others. In 3D printing products, several variables can be observed to produces specific responses desirable. Some of the responses are the efficiency of materials, dimensional accuracy of mechanical, and others. This research was conducted to compare ABS and PLA materials in the fused deposition modeling process. The strength and dimensional accuracy are the response that used in this study. The study reports that ABS has more significant tensile strength than PLA. The tensile strength of ABS is 7.66 MPa and 1.79 for PLA. PLA found has a more accurate dimension compare to ABS. Both on length and thickness, deviation of PLA lower than ABS. On a length, deviation of PLA was 0.06 mm and 0.86 for ABS. On thickness, deviation of PLA was 0.04 and 0.05 for ABS.

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.
