AI Verdict
This 405nm UV-curing resin with wax is for printing thicker designs and metal parts, offering easier burnout and high resolution for both new and experienced users.
This resin is designed for easier burnout and printing of thicker castable models, making it accessible for beginners and specific applications like jewelry and dental. However, its wax content makes prints softer and potentially harder to dial in print settings compared to non-wax resins.
If you need to consistently print extremely fine, delicate filigree without extensive support tuning, look for a castable resin specifically optimized for intricate details and less prone to brittleness.

Pros
- Contains wax, making it easier to burn and leaving less ash during burnout.
- Does not require a very dry environment or special additives for printing and burning.
- Produces models with high resolution and a smooth surface quality.
- Exhibits good plate adhesion during printing.
- Compatible with most LCD, DLP, and SLA 3D printers.
- The true blue color helps in identifying potential print flaws.
Cons
- Prints are soft and weak due to wax content, often requiring beefier supports to prevent breakage.
- Can be marginally harder to print, demanding precise print profiles for optimal results.
- Some users report stickiness and difficulty cleaning after curing.
- Requires a thorough UV cure, which may be longer than for some other resins.
- The cured prints can be brittle.
Dimension Scores
It offers high resolution, captures complex features, and provides smooth surface finishes with high-precision details.
It's easier to print than many castable resins, doesn't need special environmental conditions or additives, and has good plate adhesion, though some users need to dial in settings and use beefier supports.
It is widely used for thicker designs, metal parts, jewelry, and dental applications, and is compatible with most LCD DLP SLA printers.
Prints are soft and weak due to wax content and can be brittle when cured, requiring careful handling and strong supports.
Best For
- Thicker designs such as bracelets, large pendants, medals, and coins.
- Metal parts and jewelry casting.
- Dental applications.
- Users new to castable resins seeking an easier entry point.
Not Recommended For
- Printing extremely thin filigree models without extensive support planning and tuning.
- Users who expect a completely non-sticky post-cure without specific cleaning methods.
Watch Out For
- Prints can be soft and weak, leading to breakage during removal if supports are not adequate (e.g., 1mm tips might be too small, needing 0.5mm or 0.6mm with deep penetration).
- Requires precise print profiles to avoid overexposure and clogged details, such as small holes.
- Can remain sticky after curing, even with new undiluted IPA washes lasting up to 15 minutes.
- The resin may arrive frozen in colder temperatures, necessitating 2-3 hours indoors to defrost and 2 minutes of shaking before use.

What Buyers Say
Many users find this resin lives up to its claims of easier burnout and clean casting, especially for thicker items, making it a solid choice for those new to castable resins. The true blue color is often appreciated for highlighting print flaws. However, the wax content can make prints soft and require careful support planning, and some users struggle with stickiness after curing.
“Man, this stuff burns out so much cleaner than the purple, but seriously, those prints are like butter, gotta go heavy on the supports or they just snap.”
Common Praise
- Burns out cleanly with less ash.
- The true blue color helps in identifying print flaws.
- Works well for casting thicker models.
- Does not require glycerin for post-curing.
- Achieves high resolution and detail capture.
Common Complaints
- Prints are soft and weak, prone to breakage, requiring heavy supports.
- Can be sticky and hard to clean after curing.
- Requires precise print profile tuning to avoid issues like overexposure or support failures.
- Cured prints can be brittle.
Ownership Tips
- The wax content means prints are more flexible before curing but can become brittle after.
- Experimenting with support settings is crucial to prevent print failures and damage during removal.
- Thorough post-curing is essential for a clean burnout, even without glycerin.
- The blue color, while helpful for inspection, can make it harder to see fine details during the initial print process for some.
Frequently Asked Questions
Does this resin require special post-processing like glycerin?
No, True Blue is designed for a more conventional cure and does not require glycerin, unlike some older castable resins like Cast Purple.
Can this resin be used for thick models?
Yes, its wax-based formulation makes it easier to burn out thicker designs such as bracelets and large pendants.
Is it easy for beginners to use?
Yes, it is designed to be easier to print than other castable resins, not requiring a very dry environment or special additives, making it suitable for new users.
What kind of 3D printers can I use this with?
It is compatible with most LCD, DLP, and SLA 3D printers.
What temperature should the resin be for printing?
The ideal printing temperature for this resin is between 25-35°C (about 77°F).
Buying Guide
When you're looking at castable resins, you're basically trying to turn a 3D print into a metal object. The resin needs to print accurately, but more importantly, it needs to burn away completely in a furnace without leaving any ash. Leftover ash means defects in your final metal piece.
Wax Content
This isn't just some random ingredient; wax in the resin helps it burn out cleaner and easier, especially for thicker models, reducing the chance of ash residue in your mold.
Resolution
This tells you how fine the details your printer can capture will be. For jewelry or small parts, you want high resolution so tiny engravings or intricate designs come through clearly.
Burnout Schedule
This refers to the specific heating process needed to remove the resin from the mold. A resin that follows a 'common' burnout schedule means you won't need specialized equipment or a complicated, unique process.
Alternatives
If you're consistently printing extremely delicate, thin structures and finding this resin too soft or brittle, look for castable resins marketed specifically for ultra-fine detail and rigidity, even if they require a more complex burnout process or higher cost.
