24 reviewsThe objective of this study is to improve prototypes produced by fusion deposition
modeling (FDM). FDM, a method of rapid prototyping, produces parts with desirable
engineering properties. A new drive and extrusion method for continuous and indefinite
deposition of ABS is developed. Process improvements include adding a machining station to
tighten tolerances. Research is initiated into 5-axis deposition. which aims to reduce stairstepping
errors associated with standard 3-axis deposition. Metrology comparisons to current
industry FDM machines are made showing the improvements implemented tighten tolerance
ranges, while using a larger nozzle orifice diameter to reduce build times.
