3D-ADD HDC1 High Density Concentrate for increasing the density of 3D resins

Product description

3D-ADD HDC1 High Density Concentrate is a high density biocompatible paste designed for increasing the density of 3D resins.

This additive permits making materials with specific densities by mixing 3D-ADD HDC1, with calculated density c. 5 g/mL, with 3D resins, most of them with densities c. 1 g/mL, without affecting significantly their original mechanical properties.

Application framework

Designed for use as a density-adjusting additive in SLA, DLP and LCD vat photopolymerization workflows for custom density refinement of compatible 3D resins.

Typical applications

• Increasing the density of any 3D resin
• Custom density adjustment of compatible 3D resins
• Preparation of materials with specific target densities
• High resolution dense printed parts after mixing with compatible 3D resins

Measured physical properties

• Calculated density: c. 5 g/mL
• A lower density may appear due to air entrapment
• Resolution: up to 20 micron
• Shrinkage: very low
  

Functional performance characteristics

• High density biocompatible paste
• Ideal for increasing the density of any 3D resin, without affecting significantly their original mechanical properties
• Permits making materials with specific densities by mixing 3D-ADD HDC1 with compatible 3D resins
• Light peach color
• It causes whitening of 3D resins
• Ultra safe, pictograms free
• High resolution

Processing and handling performance

• Printable by most commercial and professional SLA, DLP & LCD 3D printers once mixed with compatible 3D resins
• Available in 3 versions:
• LipoPhilic LP version with HLB: < 7.5 (Ultra Low Water Absorption ULWA grades)
• Medium Hydrophilicity MHP version with HLB: 7.5-12
• High HydroPhilicity HHP version with HLB: >12
• Supplied as a kit, which contains the product, one graduated beaker and one empty 250 mL black bottle to measure, mix, keep and protect the 3D resins from daylight
• Please do not expose any 3D resins to natural or room light to prevent their curing
• Calculation of desired density: % 3D resin x (1/100) + % 3D-ADD HDC1 x (5/100)

Chemical and safety characteristics

• Biocompatible
• Ultra safe, pictograms free
• Organo-tin free

Testing & processing disclaimer

Final density, printability, color change, mechanical performance and workflow suitability depend on the base resin, additive ratio, mixing quality, air entrapment, printer settings and full processing workflow, and must be validated by the user.

Disclaimer

This material is supplied as a professional manufacturing additive and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.
