Formlabs Castable Wax 40 Resin (Form 4) - 1L is a highly filled 40% wax photopolymer specifically formulated for the high-speed LFD technology of the Form 4 ecosystem. This material is engineered to simplify the transition from digital 3D prints to lost-wax investment casting, providing the most traditional wax-like experience in the Formlabs range. Consequently, Formlabs Castable Wax 40 Resin (Form 4) - 1L ensures an exceptionally clean burnout with zero ash residue, making it the premier choice for heavy jewellery pieces and thick-walled geometries.
Mechanical Properties of Formlabs Castable Wax 40 Resin (Form 4) - 1L
The structural integrity of this resin is defined by a Tensile Modulus of 220 MPa, providing sufficient stiffness for intricate stone setting whilst remaining easy to hand-finish. This lower modulus compared to standard resins allows for slight flexibility, which is ideal for "try-in" fittings. Furthermore, the Heat Deflection Temperature (HDT) of 42°C at 0.45 MPa ensures that the Formlabs Castable Wax 40 Resin (Form 4) - 1L patterns remain stable during investment but evacuate the mould rapidly during the burnout cycle to prevent expansion-related cracking.
Regarding surface characteristics, the material features a Shore Hardness of 77D, offering a tactile feel that closely mimics traditional carving wax. This specific hardness level on the Shore D scale allows for crisp detail retention whilst being soft enough for manual post-print adjustments. Furthermore, the Formlabs Castable Wax 40 Resin (Form 4) - 1L does not require post-curing, which significantly accelerates the production workflow. This efficiency allows laboratories to move from a finished print to a castable flask in a single afternoon.
It is important to note that whilst this material is highly effective for dental models and patterns, there is currently no ARTG Note associated with this resin for long-term intraoral use. The Formlabs Castable Wax 40 Resin (Form 4) - 1L is strictly intended for use as a sacrificial pattern in investment casting workflows. By utilizing the Formlabs Castable Wax 40 Resin (Form 4) - 1L, jewellers and dental technicians can achieve professional-grade results with a material that behaves predictably under standard burnout conditions.
