Effect of the Temperature within the Building Chamber on the Tensile Strength of TPU and ABS Materials

Abstract

Fused deposition modeling (FDM), also known as fused filament fabrication (FFF), is the most widely used additive manufacturing technique because it offers several key advantages: material flexibility, low cost, high prototyping precision, and ease of use. The mechanical properties of 3D printed products depend on many factors, and one of the most important is the complete control over the temperature within the building chamber. However, research on the influence of chamber temperature is still minimal. This research probes the impact of chamber temperature on the mechanical properties of the printed material, precisely the thermoplastic polyurethane (TPU) and acrylonitrile butadiene styrene (ABS) materials, by using the FFF printing method. This research analyzes the tensile strength of TPU and ABS printing materials by testing printed samples at three different building chamber temperatures (30, 45, and 60 °C). From the analysis data, the study shows that the effect of building chamber temperature on tensile strength of printed parts, and also recommends that to have the best tensile strength for printed parts, the building chamber temperature of both TPU and ABS should be between 30 and 45 °C.
