Last year at Construct3D I presented on printing functional and strong parts. After the presentation I was asked a lot of follow up questions on materials, designs, and more.
This year I want to offer a workshop on the topic of printing strong functional parts. In the workshop I will lead the group through gaining an understanding of material properties, general print settings that will impact part strength, part design changes for strength, generative design, tolerancing, fastening, and material applications with tips on printing.
Projected Outline for Presentation
General design principles Geometry and its impact on strength Moment of Inertia
General material properties Define, Explain, and Examples of Rigidity Toughness Layer adhesion
More specific material properties Materials information and resources Amorphous and crystalline structures Define, Explain, and Examples of Flexural Strength Tensile Stress Heat Deflection Temperature Impact Material Safety and Data Sheets (MSDS) Technical Data Sheets (TDS)
Failures of parts Bending Tension Compression Crack propagation
Designing for strength Direct Modeling
Design choices planning for 3D printing Fasteners/adhesives/fits
Print settings for strength Research driven information on infill types and percentages Impact of layer choices, temperatures, etc.
