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.

• Filament UV Resistance: How well the part holds up to water.

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