3Dresyn Perfect Cast HS1 Bio, Heat Soluble, Meltable, Flowable & Castable photopolymer bio based solid wax

3Dresyn Perfect Cast  HS1 Bio is our Heat Soluble / Meltable Flowable & Castable photopolymer bio based solid wax for top down SLA & DLP printers.

Features and benefits:

• photoreactive solid 3D resin for Direct investment Casting "DC" which melts at 32ºC before printing
• once printed/cured it has very low melt viscosity flowing like molten wax for 100% removal from the investment mold by gravity in the upside down position for 100% ash free burn-out: it is non rubbery material upon heating as state of the art alternative 3D resins
• bio based from renewable resources: >70% bio content
• supplied in cyan, magenta, yellow, black and white colors
• cyan, magenta, yellow and specially black provide higher resolution than white 
• ideal for relatively thick prints rather than filigree ultra fine detailed printing with top down printers
• Melting point as supplied before printing: 32ºC
• Melting point after printing and postcuring: 47ºC
• reduced brittleness for a wax material
• Typical printing speeds at different printing settings: 
• exposure times 20-25 seconds for 50 microns z layers with low power <1 mW/cm2 printers
• exposure times 10-15 seconds for 50 microns z layers with medium power 1-2 mW/cm2 printers
• exposure times <10 seconds for 50 microns z layers with high power 5-15 mW/cm2 printers
• prints can be cleaned in eg warm water at 33-34°C to melt the uncured resin from the surface of prints
• tensile and flexural strength <2 MPa
• Young modulus <800 MPa
• elongation <2%
• postcuring in air or in water in a light box at room temperature for 1 hour is recommended for increasing the curing and melting point up to 47ºC
• castable with excellent burn-out without any imperfections even with cheap gypsums
• easy and clean burn-out with 0% residual ash content
• safe, without any toxic pictograms
• very low viscosity (<100 cps at 35ºC)
• no shrinkage during 3D printing
• 100% elimination by gravity off the mold for perfect castings
• no expansion during burn-out
• organo-tin free
• printable with top down printers with temperature control of the resin at 33-34ºC  
• not recommended for bottom-up printers because of the difficulty of ensuring constant and uniform printing temperature at 33-34ºC in the printer: in the resin tank and the build platform
• prints can either melt during printing if over heated or
• resin can solidify around the prints if over cooled unless uniform and constant temperature is kept in the printer,
• constant temperature during printing in the resin tank and build platform is crucial for achieving good results
• level of printing difficulty: very high. Recommended only for research purposes. Alternatively, use the easy printable 3Dresyn Perfect Cast HS2 MF Bio, Heat Soluble, Meltable, Flowable & Castable photopolymer bio based liquid 3D resin

INSTRUCTIONS FOR USE IFU FOR TOP-DOWN PRINTERS

• 3Dresyn perfect Cast HS1 is solid at room temperature. To melt the resin warm it prior to printing to 33.5°C.
• Warm the bottle of 3Dresyn Perfect Cast HS1 in a water bath, in an oven
• Once the resin is liquid, pour into the resin tank AND heat and keep the temperature at 33.5ºC . Allow 15-30 minutes for temperature of resin to stabilize.

PRINTING

• After warming the material using any of the options above it is important to allow the material to stabilize to the printer temperature. Wait 30 minutes before starting the print. Stir material well with a spatula prior to printing to verify material is liquid.

CLEANING

• Rinse parts thoroughly under warmed water at 33-34°C. Allow parts to dry thoroughly after cleaning

POSTCURING

• Postcuring for 30-60 minutes in a light box will increase the cure and melting point up to its maximum: 47ºC

INVESTMENT CASTING

• Since the material melts completely at above 47ºC, any gypsum or phosphate investment can be used since it is fully eliminated by gravity in the upside down position

*Note: warning: this product is only recommended for professional top down printers because precise control and assurance of homogenous temperature distribution in the printer is crucial for successful printing, otherwise the prints either will melt during printing if the temperature is too high, above 35ºC, its green state melting point, or the liquid resin will solidify if its temperature is too cold, below 33ºC

ALTERNATIVE DIRECT PROCESSES FOR PRINTING WAX-LIKE CASTINGS:

• by direct printing castable resins 
• Printing of water soluble sacrificial heat burnable like wax (without melting but without burst) with 3Dresyn Perfect Cast LPP for low power multicolor LCD printers and 3Dresyn Perfect Cast HPP for High power Printers (monochrome LCD, DLP, and laser printers), which are ideal for printing castings for investment casting with excellent burn out without any imperfections even with cheap gypsums
• by direct printing water soluble sacrificial resins 
• Printing of water soluble sacrificial castings with 3Dresyn Perfect Cast WS1, which is ideal for printing steam and water soluble castings for investment casting with even cheap gypsums 

ALTERNATIVE INDIRECT PROCESSES FOR MAKING WAX CASTINGS

• by injecting wax in 3d printed durable molds (for molds which are not intertwined with the injections):

• Printing of an durable molds with 3D resins for printing durable molds,

  such as 3Dresyn IM-HF and 3Dresyn IM-F which are ideal for printing durable soft and flexible molds for injection of 3Dresyns waxes or traditional waxes

• by injecting wax in "easy breaking" cocoon sacrificial molds (for molds intertwined with the injections):

• Printing of easy breaking cocoon sacrificial molds with easy breakable cocoon sacrificial 3D resins, such as 3Dresyn IM-SF Cocoon and 3Dresyn IM-SF Cocoon MF Bio, which are ideal for printing easy breaking sacrificial soft and flexible molds for injection of injection of 3Dresyns waxes or traditional waxes

• by injecting wax in water soluble sacrificial molds (for molds intertwined with the injections):

• Printing of water soluble sacrificial molds with water soluble sacrificial 3D resins, which are  ideal for printing water soluble sacrificial molds for injection of  3Dresyns waxes or traditional waxes
