Wax-like filaments and related materials are increasingly used for investment casting patterns, supports, and wax replica production in 3D printing workflows. This guide highlights five products that are well-suited for Lost Wax investment casting, support removal, and clean burn-out. Each option offers different balances of polishability, burn-out behavior, and process compatibility. Read on to compare features, materials, and practical considerations to help you choose the right filament or resin for your casting project.
| Product | Brand | Type | Notes |
|---|---|---|---|
| PolyCast Filament 0.75 kg | POLYMAKER | 1.75 mm, Filament | Low tooling, clean burn-out |
| PolyCast Filament 3 kg | POLYMAKER | 1.75 mm, Filament | Large-volume casting patterns |
| YXPOLYER PVA Filament | yxpolyer | 1.75 mm, Filament | Water-soluble support material |
| Gizmo Dorks 3D Printer Filament HIPS | Gizmo Dorks | 1.75 mm, Filament | Alternative support/solvent-friendly |
| SUNLU 10K Red Wax Resin | SUNLU | Resin, 405 nm | Wax-like resin for MSLA/DLP |
Note: Each product serves different roles in a wax-pattern workflow—from investment casting filaments to water-soluble supports and resin-based wax alternatives. When selecting, consider burn-out behavior, surface finish, compatibility with your printer, and whether you need easy removal or high precision for casting patterns.
Polymaker PolyCast Filament 0.75kg for Investment Casting
PolyCast is designed specifically for creating investment patterns used in casting applications. It helps reduce tooling costs and lead times by enabling direct 3D printed patterns without traditional molds. The filament supports high polishability via Polymaker’s Layer-Free technology, delivering superior surface quality and minimizing post-processing after casting. Importantly, PolyCast burns off cleanly in plaster without leaving ash, contributing to defect-free metal parts.
Key features:
– Investment Casting with PolyCast for cost and time savings
– Layer-Free polishability for sleek cast surfaces
– No ash burn-out for cleaner plaster and metal parts
Polymaker PolyCast Filament 3 kg for Investment Casting
This larger PolyCast spool expands production capacity for investment casting workflows. Like its smaller sibling, it supports clean burn-out and precise finishes, helping to streamline the transition from 3D printed pattern to metal part. Its Polishability remains high with Layer-Free technology, reducing post-casting refinements.
Key features:
– Large 3 kg spool for higher-volume patterns
– Clean burn-out and high surface quality
– Compatible with Layer-Free polishability for smooth casts
YXPOLYER PVA Filament For 3D Printing Supports
PVA filament provides rapid water-dissolving supports ideal for complex geometry. The upgraded formula dissolves in cold water within hours and at warmer temperatures more quickly, enabling efficient, residue-free support removal. It bonds well with common printing materials like PLA and PETG, ensuring stable dual-extrusion prints while remaining RoHS/REACH compliant and non-toxic.
Key features:
– Fast water dissolution for easy support removal
– Safe, low-odor, RoHS/REACH-compliant formulation
– Reliable adhesion for complex geometries
Gizmo Dorks 3D Printer Filament HIPS
HIPS filament offers an alternative for support material or certain casting-related tasks. This white 1 kg spool is designed for consistent diameter and roundness, providing stable prints and reliable performance. HIPS is known for good impact resistance and compatibility with various acetone-based post-processing workflows, which can be relevant in some casting-prep steps.
Key features:
– 1.75 mm filament with strong dimensional stability
– High roundness tolerance for dependable prints
– Compatible with common post-processing methods
eSUN Water Soluble PVA Filament 1.75mm
eSUN PVA is a water-soluble support material that dissolves after printing, reducing the effort required to remove supports from complex geometries. It offers stable dimensional tolerance and low risk of clogging or tangling during printing. The filament is designed for reliable performance with PLA, PETG, and ABS, supporting smoother dual-extrusion workflows.
Key features:
– Water-soluble support for complex parts
– Stable tolerance and low clog risk
– Non-toxic, RoHS-compliant formulation
Buying Guide: Wax-Like Filaments And Casting Considerations
- Burn-out performance: For investment casting, select materials that burn out cleanly without ash or residue. PolyCast is engineered to minimize waste in plaster and metal casting steps.
- Polishability and surface finish: Layer-Free technology can yield smoother cast surfaces, reducing post-processing and rework.
- Support strategy: If you need soluble supports, PVA options enable easy removal without damaging the print. For complex geometries, combine PVA with a compatible main material.
- Printer compatibility: Ensure filament diameter tolerance and roundness meet your printer’s tolerance to avoid jams and inconsistent extrusion.
- Material safety and cleanup: Consider RoHS/REACH compliance and safe disposal of wastes from burn-out or dissolution processes.
- Workflow integration: Align materials with your existing casting process, including plaster investment steps and furnace burn profiles to achieve defect-free metal parts.
- Resin alternatives: Wax-like resins such as red wax 10K can be used in MSLA/DLP workflows for high-detail patterns, though they may require different burn-out considerations compared to filaments.
These options cover a range of uses—from direct investment casting patterns with clean burn-out to dissolvable supports that simplify complex prints. When building a casting workflow, consider whether you prioritize surface finish, ease of post-processing, or print stability, and choose materials that best align with your equipment and production goals.
