The 3Dresyns team can custom-design water-soluble sacrificial 3D printed resins (and support materials) for temporary, removable 3D printed structures in applications where printed materials must be sacrificed, removed, or eliminated using water or alcohol.
Typical applications
-
Plastic Injection Molding
- Sacrificial molds for injection temperatures above 110–190°C for plastics (thermoplastics, conventionally initiated thermoplastics, thermosets, etc.).
-
Ceramic Injection Molding (CIM)
- Sacrificial molds for injection temperatures above 110–190°C.
-
Metal Injection Molding (MIM)
- Sacrificial molds for injection temperatures above 110–190°C.
-
Sacrificial inkjet supports
- Water-soluble inkjet support 3D resins, with differentiated hardness and rigidity.
-
Direct 3D printing of ceramics and metals
- Soluble 3D printed resins to enable ultra-fast debinding and sintering cycles.
-
Investment casting in investment molds (e.g., gypsum molds)
- Water-soluble casting resins removable with steam cleaner machines at high steam pressure (e.g., 7 bar) to eliminate the casting resin from the investment mold for jewelry, dental, and related investment casting applications.

Features and benefits
Cost-effective production of 3D printed water-soluble sacrificial molds for injection molding of intricate complex-shaped parts where the mold and the injected material are entangled or intertwined.
- Designed for intricate, complex, and entangled molds due to high dissolution speed in water.
- Excellent printability on professional SLA, DLP, LCD, and Inkjet 3D printers, including MultiJet printers that do not use water-soluble supports (also suitable for PolyJet printers when used with non-water-soluble supports, such as meltable supports or soft easy-breakable supports).
- Broad customization capabilities from soft and flexible grades to tough and very rigid grades at high temperature:
- Tg from -10 to >200°C
- Elongation from <1–10% and up to 100%
- Fast solubility in tap water with minimum swelling.
- No microcracking when used as 3D binders for direct printing of ceramics and metals.
- Very high resolution.
- Very low shrinkage.
- Metal-free.
Dissolution behavior
Dissolution in water typically occurs within 3–6 hours (depending on part thickness) for 3D printed water-soluble resins.
