For a long time, ABS was unchallenged when it came to high-strength and durable 3D prints—until PETG arrived. So, how do these materials stack up? PETG and ABS are both valued for their durability. Source: All3DP ABS , short for acrylonitrile butadiene styrene, was among the earliest of materials used in FDM 3D printing. It’s one of the most common plastics today, used in processes like injection molding to create anything from airplane seats to LEGO bricks. When PLA came along, it dethroned this long-standing champion as a general-use material. Now, PETG , polyethylene terephthalate glycol, threatens to do the same for high-strength applications as well. Also referred to as “copolyesters”, the various blends of PETG are described as striking the perfect balance between ABS’s strength and PLA’s ease of use. So, how does good-old ABS stack up against this new range of materials? Let’s find out. Whereas it […]
