Want to skip the guesswork and design your own parts in 1 day?

I took everything I learned from measuring, designing, and 3d printing and turned it into a 1-Day Car Parts Design Workshop.

Learn to go from idea → CAD → 3D printed part that survives in your car, without months of trial and error.

3D FILAMENT TOOL DETAILS

• Filament Stiffness: How much force a part can take before breaking. Higher MPa = better strength.

• Filament Heat Resistance: Temp that part can withstand before softening, deforming, or losing strength.

• Filament Water Resistance: How well the part holds up to water (reduced water absorption).

• Filament UV Resistance: How well the part holds up to UV sunlight exposure (reduces washing out colors and increased brittleness)

• Dry Before Printing Requirements: The manufactures recommendation if the filament should be dried prior to 3d printing.
