3Dresyn Perfect Cast HS2 MF Bio, Heat Soluble, Meltable, Flowable & Castable photopolymer bio based liquid 3D resin

3Dresyn Perfect Cast HS2 MF Bio is our Heat Soluble / Meltable Flowable* & Castable photopolymer bio based and monomer free ultra safe liquid 3D resin for heated top down and bottom-up SLA, DLP & LCD printers. 

Features and benefits:

• photoreactive liquid 3D resin for Direct investment Casting "DC" which melts above 100-200ºC, flowing like real wax after printing*
• once printed/cured it has low melt viscosity upon heating flowing like molten wax* for easy removal by gravity from the investment mold in the upside down position for 100% ash free burn-out
• bio based from renewable resources: >75-80% bio content
• monomer free as supplied for ultra safe handling and printing
• supplied in clear and cyan, magenta, yellow, black and white colors
• ideal for both relatively thick prints and filigree ultra fine detailed printing
• liquid 3D resin as supplied which becomes a flexible thermoplastic solid after printing melting like wax
• thermoplastic with melting temperature range after printing and postcuring: >100-200ºC*
• typical printing speeds at different printing settings: 
• exposure times <20-25 seconds for 50 microns z layers with medium power 4-8 mW/cm2 printers (monochrome LCD printers)
• exposure times <10-15 seconds for 50 microns z layers with high power >10-15 mW/cm2 printers (high power DLP printers)
• prints can be cleaned in warm Cleaning Fluid UNW2 Bio
• Shore hardness D55-65 
• tensile and flexural strength <4 MPa
• Young modulus <60 MPa
• elongation <1-2%
• postcuring is not required 
• castable with excellent burn-out without any imperfections even with cheap gypsums
• easy and clean burn-out with 0% residual ash content
• Heat Deflection Temperature HDT after curing c.25-30ºC@0.45MPa
• no shrinkage during 3D printing (<1%)
• elimination of molten prints* by gravity off the mold for perfect castings
• prints are 100% soluble in acetone
• no shrinkage and no expansion during burn out
• durability of the resin tank
• organo-tin free
• easy printability vs 3Dresyn Perfect Cast HS1 Bio, Heat Soluble, Meltable, Flowable & Castable photopolymer bio based solid wax
• printable with heated top-down and bottom-up printers                                        
• recommended printing temperature 40-45-50ºC or higher
• Typical viscosity:
• <90.000 mPas at 25ºC: poor flow and very sticky (non-printable)
• <30.000 mPas at 30ºC: medium flow and very sticky (non-printable by bottom-up printers but printable with top-dowm printers with Dr blade)
• <10.000 mPas at 35ºC: good flow but sticky (printable by bottom-up with high quality FEP films and with top-dowm printers with Dr blade)
• <7000 mPas at 40ºC: very good flow  but still sticky (printable by bottom-up with high quality FEP films and with top-down printers with Dr blade)
• <2500 mPas at 45ºC: very good flow with lower stickiness (printable with bottom-up printers with medium quality FEP films and with top-dowm printers without Dr blade))
• <800 mPas at 60ºC: excellent flow with reduced stickiness (printable with bottom-up and top-down printers but fine detail prints can deform if not properly supported due to excessive thermoplasticity)
• <400 mPas at 65ºC: excellent flow with minor stickiness (printable with bottom-up and top-down printers but too fine detail prints can deform if not properly supported due to excessive thermoplasticity)
• level of printing difficulty: medium. Recommended for professional printer users

*Note. depending on Fine Tuner type, its dosage, printing and postcuring specifications, including light wavelength, power and total energy dosage the melting temperature range can vary and be >100-200ºC or higher. In some cases prints at high temperature may rather thermally degrade and burn out instead of melting. In any case, perfect casts without imperfections are obtained.

INSTRUCTIONS FOR USE IFU FOR BOTTOM-UP AND TOP-DOWN PRINTERS

• 3Dresyn perfect Cast HS2 MF Bio is a viscous liquid at room temperature which needs to be warmed during printing to decrease its viscosity and stickiness

PRINTING

• Follow 3Dresyns Instructions For Use IFU
• Printing temperature 35-45ºC (or higher such as 50ºC for reduced peeling force and when printing big prints)
• The higher the temperature the lower the viscosity and stickiness but the lower the rigidity of prints during printing
• Use high density of thick supports to prevent deformation of prints since it is a flexible thermoplastic 3D resin
• Excessive light exposure may reduce melt flow and cause that the prints become rubbery upon heating, thermally degrading and burning out instead of melting. In any case, perfect casts without imperfections are obtained

CLEANING

• Rinse parts thoroughly in warm Cleaning Fluid UNW2 Bio for easy removal of uncured resin 

POSTCURING

• Light postcuring is not required nor recommended
• Light postcuring in a light box will increase the cure and melting point
• Excessive light exposure may reduce melt flow and cause that the prints become rubbery upon heating, thermally degrading and burning out instead of fully melting with low melt viscosity. In any case, perfect casts are obtained

INVESTMENT CASTING

• Since the material may melt or degrade thermally, any gypsum or phosphate investment can be used
• Position it upside down initially for its elimination as a molten liquid by gravity
• Position it upright for its total ash free elimination
