Design Guidelines for STEP Technology with ABS Material

This guide provides best practices and considerations for optimizing designs for the Selective Thermoplastic Electrophotographic Process (STEP™) using ABS material. It outlines the capabilities of the STEP 3D printing process, which can produce a variety of part sizes with high surface finish quality, dimensional accuracy, and material properties comparable to injection molding. The document details essential aspects of part design, construction, file preparation, and post-processing for STEP technology. It emphasizes the precise control of material deposition, allowing for fine features and good accuracy. Specific guidelines are provided regarding layer thickness, accuracy, hole diameters, clearance for assemblies, and escape vents for support material removal. The document also discusses the importance of part strength, build nesting, cost efficiency, print orientation, and post-processing techniques such as bead blasting and chemical vapor smoothing. These guidelines serve as a foundational resource for engineers looking to leverage STEP technology in their designs.
