Strengths of Three Materials Combine to Form Composite 3D Printed Components https://ift.tt/2yErfrU In a paper entitled “On the 3D printing of recycled ABS, PLA and HIPS thermoplastics for structural applications,” a group of researchers discusses multi-material 3D printing for structural applications. The materials they use are recycled ABS, PLA and HIPS to create composite parts. The point was to combine the materials so that the final component benefited from the respective strengths of each material.
The researchers 3D printed the sample components, which had four layers of each material. Testing was then performed on the components, including MFI characterization, differential scanning calorimetric (DSC) analysis, tensile testing, Lee’s disc thermal conductivity measurement, flexural testing and pull out testing. ABS, PLA and HIPS were found, through DSC testing, to be compatible with each other, all of them having similar ranges of integral heat value.
Several conclusions were made from the study, as stated by the researchers:
Overall, the three materials were compatible with each other, and their strengths worked together to create composite components that were superior to single-material components. With the growing sophistication of 3D printers, and the greater accessibility of printers with multimaterial capabilities, it is becoming easier to 3D print composite components like these for functional applications that benefit from the best characteristics of ABS, PLA and HIPS. Authors of the paper include Ranvijay Kumar, Rupinder Singh and Ilenia Farina. Discuss this and other 3D printing topics at 3DPrintBoard.com or share your thoughts below.
