Cast 3D Printer Resin True Blue - Easier Burnout, High Resolution

In this review the Siraya Tech Cast True Blue resin is assessed for people who print jewelry, thick metal patterns, or dental parts and need a castable material that burns cleanly. The single biggest reason to consider it is its wax-infused formulation that makes burnout noticeably easier and leaves minimal ash, which simplifies investment casting for thicker pieces. Reviewers will find it useful when reliable burnout and high surface quality are more important than extreme stiffness.

Key Features

• Easier to burn: The wax content reduces ash and facilitates a cleaner burnout, which is especially helpful for solid or thick castings like bracelets and big pendants.
• Easier to print: This resin prints without special drying or additives, so both new and experienced users can achieve good plate adhesion and faster prints.
• High surface quality: The bright true blue color produces a clear gloss and smooth finish that highlights fine printing details for jewelry prototypes.
• High resolution and softer feel: The formula captures ultra-fine structures and complex features while remaining softer than cast purple, aiding detail reproduction.
• Wide compatibility: Usable across most LCD, DLP and SLA 3D printers that cure at 405nm, making it practical for a variety of workflows.

Who It's For

The resin is best for hobbyists and small workshops that cast jewelry, medals, coins, larger pendants or metal parts and want a material that burns out cleanly from thicker prints. Dentists and labs creating castable models may also benefit from the reliable burnout and fine surface finish.

It is less suitable for users who need very rigid masters or who prioritize absolute edge hardness; some users reported mixed print outcomes and occasional layer adhesion issues, so those requiring perfect first-time prints for production runs should validate settings first.

Pros & Cons

Pros

• Burns out cleanly with minimal ash due to wax content, simplifying casting.
• Prints without special drying or additives, easing setup for new users.
• Produces a glossy, high-resolution surface that reveals fine detail for jewelry and small parts.
• Good compatibility with most 405nm LCD, DLP and SLA printers.

Cons

• Some users report mixed print reliability and occasional layer adhesion problems that require tuning.
• Being softer than other cast resins may not suit models that need high rigidity during handling.

Specifications

Our Verdict

The Siraya Tech Cast True Blue resin is a practical choice for makers who need castable prints that burn out cleanly and show fine detail, particularly for thicker jewelry and metal parts. It offers good ease of use and excellent surface quality for the price, though print settings should be validated for reliable layer adhesion. For casting-focused workshops and serious hobbyists it represents solid value.

Frequently Asked Questions

Will this resin work in my 405nm LCD or DLP printer?
Yes, it is designed for most 405nm LCD, DLP and SLA printers, but you should test exposure and adhesion settings for your machine.

Does it leave ash during burnout?
No, the wax-infused formula is intended to burn cleaner and leave much less ash than many non-wax casting resins.

Is this resin rigid after printing?
The True Blue cast resin is softer than some alternatives, which helps capture fine detail but may not be ideal where high rigidity is required.
