Select the Cast resin if your workflow involves creating wax patterns for metal casting in jewelry or dentistry. Both offer high resolution, but their specific formulations serve very different final goals.
Durability Versus Casting Precision
resin type and strength
Siraya Tech Fast ABS-Like Grey Resin is an ABS-like material designed for durability. It offers a combination of stiffness and toughness, making it non-brittle and strong enough to withstand accidental drops. This makes it suitable for functional industrial parts and tabletop models that need to hold up to stress. In contrast, Siraya Tech Cast 1kg Castable Resin is formulated for burning out cleanly to create metal casts. It contains wax to facilitate easier burning, which is essential for jewelry and small metal parts. While the Fast ABS-Like resin prioritizes mechanical strength for the final plastic print, the Cast resin prioritizes clean burnout properties for metal fabrication. If you need a durable final plastic part, the Fast ABS-Like option is the clear choice.
primary application
The intended use case differs significantly between these two resins. Siraya Tech Fast ABS-Like Grey Resin is recommended for a wide range of applications, from tabletop models to industrial parts. It is especially suitable for small and half-length models that require high precision and smooth surface finishes. On the other hand, Siraya Tech Cast 1kg Castable Resin is specifically developed for jewelry making, such as rings and pendants, as well as small metal functional parts for engineers and dentists. If your goal is to produce final metal components or intricate jewelry pieces, the Cast resin is the necessary tool. If you are printing durable plastic prototypes or models, the Fast ABS-Like resin is more appropriate for your workflow.
packaging size
The volume of resin you receive is a practical consideration for your budget and storage. Siraya Tech Fast ABS-Like Grey Resin comes in a 2kg package, providing twice the material volume compared to the alternative. This larger size may be beneficial if you plan to print frequently or larger models, offering more prints per purchase. Siraya Tech Cast 1kg Castable Resin is sold in a 1kg container. Since castable resins are often used for smaller, detailed jewelry items, the smaller size might be sufficient for many users. However, if you are comparing cost-per-print for large functional parts, the 2kg option of the Fast ABS-Like resin provides more material. The choice depends on your typical print volume.
print speed and fluidity
Printing speed and resin behavior during the build process are key factors for efficiency. Siraya Tech Fast ABS-Like Grey Resin is highlighted for its good fluidity, which effectively increases printing speed and success rates. The name itself suggests a focus on faster production cycles. Siraya Tech Cast 1kg Castable Resin is also described as easy to print and capable of quick prints with high resolution. However, the Fast ABS-Like resin explicitly emphasizes fluidity as a driver for speed and ease of cleaning. Both resins are compatible with 405nm UV curing, but the Fast ABS-Like resin’s specific mention of fluidity for speed gives it a slight advantage for users prioritizing rapid production of functional parts over detailed casting patterns.
cleaning and post-processing
Post-processing requirements vary based on the final goal of your print. Siraya Tech Fast ABS-Like Grey Resin is designed to be easy to clean, requiring only an air gun and alcohol spray to remove excess resin. This simple process avoids sticky residues, making it convenient for general model making. Siraya Tech Cast 1kg Castable Resin is designed for a different post-process: burning out. It is formulated to burn cleanly, which is critical for jewelry casting. While it is also easy to clean with alcohol, the primary post-processing step is investing in a burnout cycle for metal casting. If you want a quick clean-and-finish workflow for plastic parts, the Fast ABS-Like resin is more straightforward. If you need a pattern for metal, the Cast resin’s burnout properties are the key feature.
Which resin fits your needs
Jewelers and metal casting users
Choose the Castable Resin for jewelry and small metal parts. It contains wax for easier burning during the casting process. The purple color helps you see details clearly. It prints well on most LCD and DLP printers without needing special additives. This makes it ideal for creating precise metal components for rings and pendants.
Functional part and model makers
Select the ABS-Like Resin for durable tabletop models or industrial parts. It combines stiffness and toughness, so prints are not brittle. This grey resin offers high resolution and a smooth surface finish. It is easy to clean with alcohol and air. The material handles accidental drops well, making it suitable for functional prototypes and half-length models.
Users wanting larger volume
The ABS-Like option comes in a 2kg size, giving you more material than the 1kg Castable resin. This larger volume is practical for bigger prints or frequent use. The grey color provides good contrast for high-resolution details. It works with both LCD and DLP technologies. You get more prints per purchase with this durable, non-brittle material.

Frequently asked questions
Can I use Fast ABS-Like Grey for jewelry casting?
No. This resin is designed for durable functional parts, not casting. It lacks the wax content needed for burnout. The Cast 1kg resin is the correct choice for jewelry. It is formulated to burn away cleanly, leaving a precise mold for metal pouring.
Which resin is better for industrial prototypes?
Fast ABS-Like Grey is the better option. It offers high strength and toughness for functional models. The material resists breaking under stress. Cast resin is too specialized for this task. It prioritizes detail and burnout ease over the mechanical durability required for industrial prototypes.
What is the main difference in resin type?
One is ABS-like and the other is castable. Fast ABS-Like Grey mimics ABS plastic properties for strength. Cast resin contains wax for lost-wax casting processes. They serve different end goals. One builds tough objects, while the other creates molds for metal replication.
Do both resins work with LCD printers?
Yes. Both are UV-curing resins compatible with LCD and DLP printers. You can use either material in the same machine. The difference lies in the cured part. One yields a durable solid object. The other yields a pattern for casting metal jewelry or parts.
Which resin is easier to clean?
Fast ABS-Like Grey is often easier to clean for general use. It is designed for routine printing and handling. Cast resin requires careful washing to preserve its castable properties. The wax content can leave residue if not cleaned properly. Follow manufacturer instructions for each specific type.
Is Fast ABS-Like Grey brittle?
No. It is designed to be tough and non-brittle. The material combines stiffness with impact resistance. It can withstand accidental drops better than standard rigid resins. This makes it suitable for parts that need to handle physical stress or frequent handling during use.
What size options are available for each?
Fast ABS-Like Grey comes in a 2kg size. Cast resin is available in a 1kg size. The packaging dimensions differ slightly. Check your printer’s vat capacity. Ensure you have enough resin volume for your project size before purchasing. The larger pack offers more material for bigger builds.
Can I paint Fast ABS-Like Grey parts?
Yes. The cured surface accepts paint well. The grey color provides a neutral base for finishing. You can sand and prime the parts before painting. Cast resin parts are usually melted away. Painting is not a standard step for the castable pattern itself.
