Acetone-Soluble Sacrificial 3D Printing Resins

Choose your acetone-soluble sacrificial family

Use the routes below to navigate the collection by mechanical profile and sacrificial removal logic.

• Acetone-removable sacrificial systems with controlled dissolution removal route.
• Stable printing and handling during molding and casting workflows.
• Suitable for complex cavities, internal channels, undercuts and enclosed features.
• Useful for indirect manufacturing workflows where acetone release is preferred.
• Available in hard, hard-flexible and flexible sacrificial profiles.

Typical use scenarios across the collection

This collection is suitable for workflows where sacrificial printed features must survive printing and process handling, then dissolve in acetone when release is needed.

• Sacrificial molds and mandrels: removable internal or external sacrificial structures.
• Complex internal channels: solvent-release approach for hidden geometries.
• Undercuts and enclosed cavities: sacrificial parts that cannot be removed mechanically.
• Indirect manufacturing for casting and molding: printed sacrificial features inside a broader manufacturing sequence.
• Solvent-based release strategies: workflows designed specifically around acetone dissolution.

How to choose the right acetone-soluble sacrificial resin

Select the most suitable material according to the required stiffness of the sacrificial feature and the geometry it must support before dissolution.

• Need a harder sacrificial structure → choose IM-H-FAS Bio
• Need a balanced hard-flexible sacrificial structure → choose IM-HF-FAS Bio
• Need a more flexible sacrificial structure → choose IM-F-FAS Bio

• Prioritise geometry holding and stiffness → start with the hard route
• Prioritise a compromise between support and compliance → start with the hard-flexible route
• Prioritise conformability in sacrificial features → start with the flexible route
• Prioritise fast acetone-based removal → validate all routes against actual wall thickness and dissolution conditions

Decision tree summary

Use this simplified logic before detailed printing and solvent-release validation.

• Need hard sacrificial support → IM-H-FAS Bio
• Need hard-flexible sacrificial support → IM-HF-FAS Bio
• Need flexible sacrificial support → IM-F-FAS Bio

Then validate the final route under the intended geometry, cure settings, shell thickness and acetone-dissolution workflow.

Fast acetone-soluble hard sacrificial resin

For workflows requiring stronger sacrificial support, more rigid geometry holding and controlled acetone release after processing.

Fast acetone-soluble hard & flexible sacrificial resin

For workflows requiring a balance between structural hold and controlled flexibility before solvent removal.

Fast acetone-soluble flexible sacrificial resin

For workflows requiring more compliant sacrificial features with acetone-based release after processing.

An acetone-release platform rather than a general sacrificial-resin page

This collection is structured around the same controlled solvent-release logic across three different mechanical profiles, helping users choose the sacrificial behavior that best matches the supported geometry.

• IM-H-FAS Bio covers the hard route.
• IM-HF-FAS Bio covers the hard-flexible route.
• IM-F-FAS Bio covers the flexible route.

The right FAS route depends on support mechanics and solvent access

These materials are most useful when the removal objective is defined first: solvent-based release of rigid sacrificial features, more balanced removable supports or more flexible internal sacrificial geometries.

In practice, the correct path is to define the sacrificial role and acetone-access conditions first, then validate the chosen resin under the intended geometry, cure settings and dissolution sequence.
