## Description

Product Description Cast True Blue 3D Printer Resin - Easier to Burn and Print Making an excellent castable resin was never easy because if a resin is easier to print, then it is often difficult to get clean burnout. At the same time, easier to burnout resin are often very soft and challenging to print. Cast Purple was a groundbreaking resin because it was both easy to print and cast and affordable for cast resin. Now we are taking it one step further with Cast True Blue. Using the newly developed wax-based formulation, Cast True Blue UV resin is easier to burn out than Cast Purple, which expands the range of applications. This siraya tech castable resin is now possible to cast thicker model designs such as printed bracelets, large pendants, metal parts, jewelry casting, and by dentists. Like Cast Purple, Cast True Blue is field tested with commonly available casting powders. Love our Cast Purple castable resin but cast thicker designs like bracelets and metal parts? Features Easier to burn and burn more cleanly Easy to use and print High resolution Smooth model surface High precision details Following the success of Cast purple 3D resin, Siraya Tech is launching a Cast True Blue Siraya Tech Cast true blue 3d print resin is a castable resin that is even easier to burn out while having excellent resolution. This castable resin is designed for MSLA printer in mind. It can work in DLP and laser SLA printers but you would need FEP film-based vat. Since it is mostly for small jewelry, use the smallest build volume printer for printing. Easier to Burn and Print This Cast 3D print resin does not require a very dry environment or special additive to print and burn well.Both new users and experienced users can easily print the model. High Precision Details Siraya Tech castable resin’s bright true blue color shows more clear gloss and has an extremely high resolution, which can capture complex features, print ultra-fine structures. Bright True Blue When printing is first finished, Cast True Blue castable 3D print resin is in deep blue. The color may turn partially milky blue with washing and post-curing as the wax content is revealed. The such color change is expected, and the print is ready for casting. Mechanical Properties Tips： Cleaning Use a painter brush (or any brush made with hair) remove excess resins on the printed part with Use 95% concentrated Ethanol (preferred) or IPA to clean. Some form of methanol should work but make sure it does not contain acetone. Do not submerge the parts in alcohol for more than 30 seconds. After 2-3 minutes of cleaning action, remove alcohol with a hair dryer or air blower. For complex part with lots cavities, it may be a good idea to clean/dry multiple times. Dry as quickly as one can once the print is cleaned with compressed air Surface should be matte, if you see shiny spots, repeat cleaning on those spots. Post-Curing Make sure print is completely dry before proceeding. It is important to fully cure Cast to ensure clean burnout. It is also important to ensure print does not absorb moisture as it may also affect burnout results We recommend putting print in glycerine to speed up curing without getting water on the print. Curing time varies with light fixture but most likely to be over 10 minutes and longer. AVOID USING WASH AND CURE ALL IN ONE MACHINE. Fully Cured Print Should feel hard and a bit brittle. For detailed information and design of printing parameters, please see the user guide "Product guides and documents"

Review: Comparing true blue to purple - True blue is better. The print quality is higher, there is less deformation, and supports come off incredibly clean and easy. Although It doesn't look like it's as sharp as purple on hard edges and corners. It also has a much more "waxy" feel and smell compared to purple. I have also read that mixing blue and purple 50/50 can get you better results than using either resin alone.
Review: Perfect casts from this - Great resin for casting, prints well, inexpensive compared with others but does need curing.

## Questions & Answers

**Q: What is the exposure for anycubic photon mono 4k i do not find in the guide**
A: I use the anycubic photon mono 4k printer.   I use 5 to 7 second exposure setting.  Going to faster times such as 2-3 seconds has never worked.      Going to longer times don't look needed  This stuff works great. Sticks to plate every time. . I'm not in a hurry as this is for castings.  Make sure you have at least enough lift to break contact area. At least 6 mm.  Lift speed is kind of slow at 50 mm per minute. I want to give it time to break the seal between the part and bottom .  I use 30 seconds per layer on base plate to start.   With about 7 layers or so. This will make the base plate layers harder. Less time may soften it up and help get it off easy.  But not stick as well.    I clean tank every print and make sure no junk is hidden somewhere.  I level every print and use only clean resin. This stuff is the best  for castings.  Seems like curing takes many times longer under UV light.    But I look at each one and decide.  I lightly sand each model 100% . This will also help the coating material stick better.   REX

**Q: What investment are people using with this successfully? i have plasticast but hear optima prestige is better for this kind of wax -thanks!**

**Q: what is the shelf life of Siraya Tech Cast?**
A: If unopened does not really have one, I use 3 year old resins.
With open bottles of castable resins it is recommended to use fairly quickly as air/moisture can effect burnout. 
To keep cast fresh I pour some into another UV blocking bottle (amber glass) and use, this way it reduces how much air/moisture can affect the bulk of the resin.

**Q: is this resin compatible with the new elegoo mars 3 msla 4k printer? If so what are the recommended settings.**
A: hi，

Cast user guide:
https://docs.google.com/spreadsheets/d/1m2JOi054N9dFiQk2e8x1ijl09gSv_qChY_65AMDaHxI/edit?usp=sharing
It is best to cast as soon as you finalize full post curing. moisture in air can affect burnout
