Abstract Scope |
We present an additive manufacturing process, which uses the surface tension of a photo-polymer resin to suspend a film across a wide aperture and curing a pattern on the film. A horizontal film is made by dipping and raising an aperture from a shallow pool of resin and the film is polymerized selectively with a 405 nm laser. After each step of selective curing with a pattern, the build plate is moved backwards to advance the part. This process consumes a much smaller amount of resin as compared to a bottom-up vat photopolymerization machine. This paper presents the proof of concept of the process along with the machine and two parts printed using this process. Furthermore, the paper discusses the effect of process parameters such as pressure on the suspended film, and an extension of the process to a continuous interface polymerization. The process presented has the potential for in-situ additive manufacturing including 3D-printing in micro-gravity for space applications. |
