The study compared the performance of five entry level fused deposition modelling (FDM) 3D printers for a variety of attributes, including reliability, production quality, and ease of use.
Each 3D printer was used to print a range of design geometries using ABS material (except for one printer that uses a proprietary material rather than ABS), which were then analysed for quantitative measurements such as Tensile Strength and Feature Position Accuracy. Reliability was also quantified by comparing the parts completed to parts attempted, and a visual inspection was also performed.
Each 3D printer was tested to produce identical designs. Along with the accuracy of each printed piece, the study measured how often each build was successful, the number of parts completed
compared to the number sent to print, the amount of time each printer required, and any downtime.
