Recent advances in additive manufacturing technologies have already led to wide-scale adoption of 3D-printed parts in various industries. The expansion in choice of materials that can be processed, particularly using Fused Deposition Modeling (FDM), and the steady advancements in dimensional accuracy control have extended the range of applications far beyond rapid prototyping. However, additive manufacturing still has considerable limitations compared to traditional and subtractive manufacturing processes. This work addresses limitations associated with the as-deposited surface roughness of 3D-printed parts. The effects of roughness-induced stress concentrations were studied on ultimate tensile strength and fatigue life. The samples were manufactured using a …

To recycle waste material produced by fused deposition modeling (FDM) 3D printers, a recycler was designed and manufactured to convert plastic scraps into usable filament. The device does so by breaking down plastic material to a uniform size with the shredder, melting and compressing these pieces into a cylindrical strand with the extruder, and wrapping this strand around a filament spool with the spooler. As the device is mostly made from commercially-available components, it is easily maintainable and user-serviceable, while also costing less than similar devices on the market.
