Wear and Dynamic Mechanical Analysis (DMA) of Samples Produced via Fused Deposition Modelling (FDM) 3D Printing...

Area of Science:

• Materials Science
• Additive Manufacturing
• Polymer Engineering

Background:

• 3D printing (additive manufacturing) is rapidly advancing for prototyping and repairs.
• Limited data on material properties, particularly wear and thermal resistance, hinders broader adoption.
• Key polymers like PLA, PETG, HIPS, PA, ABS, and ASA are widely used but require further characterization.

Purpose of the Study:

• To investigate the wear and thermal resistance of common 3D printing polymers.
• To provide comprehensive material property data for engineering applications.
• To build upon existing mechanical property research with wear and thermal analysis.

Main Methods:

• Wear testing was conducted to measure weight loss and frictional parameters.
• Dynamic Mechanical Analysis (DMA) was used to determine storage and loss moduli.
• Materials studied include Polylactic Acid (PLA), Polyethylene Terephthalate Glycol (PETG), High Impact Polystyrene (HIPS), Polyamide (PA), Acrylonitrile Butadiene Styrene (ABS), and Acrylonitrile Styrene Acrylate (ASA).

Main Results:

• Detailed measurements of weight loss, frictional forces, and frictional work were recorded.
• Storage modulus, loss modulus, and tan(δ) were quantified using DMA.
• Comparative analysis of wear and thermal behavior across different 3D printing materials was performed.

Conclusions:

• The study provides essential data on the wear and thermal resistance of six common 3D printing materials.
• This research aids in selecting appropriate materials for specific applications based on performance requirements.
• The findings contribute to a better understanding of polymer behavior in 3D printed components.
