• Significant rigidity refinement can be achieved with 3Dresyn SA1 HV Bio and 3Dresyn HA1 HV MF Bio
• Detailed rigidity refinement can be achieved with 3Dresyn SA2 LV Bio and 3Dresyn HA2 LV Bio

Note: high Heat Deflection Temperature HDT 3D resins despite being rigid tend to be fragile and have a short lifetime, degrading thermally at high temperature. If durable materials with high HDT are needed it is recommended the use of machined polyimide, or injecting PolyAmide Imide PAI or other high HDT conventional polymers in metal or 3D printed molds.

Material performance depends on printer type, thermal control, exposure conditions, geometry and full workflow implementation. Mechanical and thermal performance must be validated by the user for each specific application.

• Ultra-high rigidity and hardness for demanding applications
• High thermal resistance up to 290 °C
• Suitable for HL and VLM manufacturing workflows
• Very high resolution and very low shrinkage
• Rigidity tunable with dedicated adjusters

This material is supplied as a professional manufacturing material and is not marketed as a finished product. Final performance, durability and process validation remain the responsibility of the user depending on printer, mold design, thermal exposure and workflow conditions.
