A process for support material removal for 3D printed parts wherein the part is placed in a media filled tank and support removal is optimized in a multi-parameter system through an artificial intelligence process which may include, but is not limited to, the use of historical data, parametric testing data, normal support removal data, and outputs from other support removal AI models to generate optimally efficient use of each parameter in terms of pulse repetition interval (PRI) and cycle time as defined by pulse width (PW). The input parameters may include heat, circulation, ultrasound and chemical reaction, which are used in sequence and/or in parallel, to optimize efficiency of support removal. Sequentially and/or in parallel, heat, pump circulation and ultrasound may vary in application or intensity. Selection of means of agitation depends on monitored feedback from the support removal tank and application of a statistically dynamic rule based system (SDRBS).

A novel polymer optical waveguide and method of manufacturing is presented herein. A digitally manufactured process is described which utilizes a micro-dispensed UV optical adhesive as the contour guiding cladding, a fused deposition modeling technology for creating a core, and a subtractive laser process to finish the two ends of the optical interconnect. The optical waveguide can be printed directly on a circuit board in some embodiments. Alternatively, using a slightly modified process including a step to bond the optical fiber to the substrate, the optical interconnect can be manufactured on a flexible substrate.

A method of and system for surface finishing an additive manufactured part. A part having a surface roughness with macroasperities is placed in a chamber with an electrolyte and an electrode. A pulse/pulse reverse power supply is connected to the part rendering it anodic and connected to the electrode rendering it cathodic. The power supply is operated to decrease the surface roughness of the part by applying a first series of waveforms including at least two waveforms where a diffusion layer is maintained at a thickness to produce a macroprofile regime relative to the macroasperities, the first series of waveforms having anodic voltages applied for anodic time periods before cathodic voltages applied for cathodic time periods to effect part surface smoothing to a first surface roughness with minimal material removal and applying a final waveform where the diffusion layer represents a microprofile regime, the final waveform having a final anodic voltage applied for a final anodic time period before a final cathodic voltage applied for a final cathodic time period to effect part surface smoothing to a final surface roughness with minimal material removal.
