Description
3Dresyn Perfect Cast HS1 Heat Soluble / Meltable for heated SLA & DLP Printers has these features and benefits:
- photoreactive wax for Direct investment Casting "DC" which melts and flows like real wax after printing or casting
- very low viscosity flow like molten wax with 100% removal from the mold by gravity and final 100% ash free burn-out
- non rubbery material after heated as state of the art 3D resins
- supplied in clear and cyan, magenta, yellow, black and white colors
- cyan, magenta, yellow and specially black provide higher resolution than clear and 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
- ideal printability with top down printers for filigree works
- printable (with restrictions) with bottom-up SLA, DLP and LCD printers with temperature control, providing the printing temperature is constant at 33-34ºC, otherwise the product can either melt during printing or solidify. Uniform and constant temperature in the printer, including the resin tank and build platform is crucial for achieving good results*
- reduced brittleness for a wax material
- fast printing speed. Typical printing settings:
- exposure times 20-25 seconds for 50 microns z layers with low power LCD printers
- exposure times 10-15 seconds for 50 microns z layers with monochrome LCD printers
- exposure times <10 seconds for 50 microns z layers with SLA laser and DLP printers
- prints can be cleaned in eg warm water at 33-34°C to melt the uncured resin from the surface of prints
- 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, bio based from renewable resources, without any toxic pictograms
- very low viscosity (<100 cps at 35C)
- no shrinkage during 3D printing
- 100% elimination by gravity off the mold for perfect castings
- no expansion during burn-out
- durability of the resin tank
- organo-tin free
- level of printing difficulty: very high. Recommended only for research purposes
INSTRUCTIONS FOR USE IFU
- 3Dresyn perfect Cast HS1 is solid at room temperature. To melt the resin warm it prior to printing. Activate the heater on printer. Settings > Temperature > Controller ON. Change Setpoint to 33.5°C.
- Warm the bottle of 3Dresyn Perfect Cast HS1 in a water bath, in an oven or in a microwave oven.
- Once the resin is liquid, pour into the resin tank or vat and place it inside the preheated printer at 33-34ºC . Allow 30 minutes for temperature of resin and printer 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 printer users 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 and below its melting point
ALTERNATIVE EASIER INDIRECT PROCESS FOR 3DRESYN PERFECT CAST HS1 CLEAR:
- Printing of an invest mold with 3Dresyn IM-SF which is ideal for printing non durable soft and flexible molds for injection of soft materials such as waxes and silicones
- Casting or injection by gravity of molten 3Dresyn Perfect Cast HS1 Clear version (or other waxes) in the 3D printed mold printed with 3Dresyn IM-SF
- After cooling, the clear mold filled with 3Dresyn Perfect Cast HS1 Clear, can be post cured in a light box for 1 hour to increase its melting temperature from 32 to 47ºC
- the soft and easy breakable mold can be easily broken in soft pieces by hand without damaging the wax
