When it comes to high-resolution jewelry making, dental models, or intricate investment casting, Siraya Tech Cast Purple has long been a favorite for its clean burnout and exceptional detail capture. However, dialing in the perfect settings for high-speed MSLA printers can sometimes feel like a balancing act.
Thankfully, the 3D printing community always comes through.
Popular 3D creator and maker 3D Maker Noob recently put Cast Purple to the test on his Prusa SL1S Speed, and the results look absolutely incredible! If you are looking to skip the trial-and-error phase and get perfect casting results right off the build plate, here is the exact formula he used to master the print.
Why Cast Purple Meets the Prusa SL1S Speed
The Prusa SL1S Speed is known for its blazing fast cure times and powerful UV optical system. Because castable resins are inherently dense and require precise light energy to cure perfectly without losing geometric accuracy, matching them with the right material profile is critical.
Siraya Tech Cast Purple is formulated to burn out cleanly without leaving ash residue, making it ideal for metal casting. By using 3D Maker Noob's dialed-in settings, you ensure that the delicate features of your model survive the fast printing process while maintaining structural integrity.
The Optimized Prusa SL1S Speed Settings (Start Point)
Here are the precise parameters shared by 3D Maker Noob for running Cast Purple on the SL1S Speed. Applying these baseline numbers will significantly improve your success rate:
| Parameter | Recommended Setting |
|---|---|
| Material Profile | High Viscosity (Crucial for proper resin flow) |
| Normal Exposure Time | 5 seconds |
| Initial Layer Exposure | 30 seconds |
| Support Pin Head Diameter | 0.6mm |
| Support Pin Head Penetration | 0.6mm |
💡 Pro-Tip on Supports:
Castable resins can be slightly heavier and require stable anchoring during the peel cycle. The 0.6mm pin head diameter and penetration settings strike the perfect balance—providing enough grip to hold the model securely while remaining easy to snap off without pitting the final surface (which would ruin a casted metal piece).
Final Thoughts & Community Results
Seeing community members push our materials to their absolute limits is what drives us at Siraya Tech. Thanks to 3D Maker Noob's testing, Prusa users now have a reliable baseline to achieve professional-grade casting models in record time.
Give these settings a try on your next project, and let us know how your burnout turns out!

My @Prusa3D SL1S Speed has been working quite a bit lately. Spent a hefty amount of time dialing in a @Sirayatech Casting Resin profile. Very happy with the result. This will be quite an amazing achievement personally, once it all comes together... In silver and gold🤩
From a @maxondbrush sculpt, to a @Sirayatech Cast resin print on the @Prusa3D SL1S to a pure Silver cast. It still blows my mind 🤯 once done, it will be the single greatest "thing" I was ever part of ❤️
