Who is it for?
Perfect for anyone printing detailed models and miniatures who wants to avoid handling large amounts of alcohol, for resin printing beginners, and for large-format printers where its low viscosity and low peel force help reduce print failures. Gray makes detail easy to see and works great as a base for painting.
What's new in V2?
Siraya has updated the formula for improved durability, maintained high detail reproduction, and better resistance to prolonged water exposure, with low volumetric shrinkage for smooth surfaces. Still low odor and easy to clean.

Washing: water works — but keep it quick
- Remove excess resin with a soft-bristle brush before washing.
- Wash with 15% alcohol (Siraya's recommendation), IPA, or plain water.
-
Do not leave parts submerged for more than 20 seconds in water or alcohol — Simple dissolves easily in water.
Post-curing
- Parts must be clean and completely dry before curing — any remaining moisture can cause cracking.
- Cure under 395–405 nm light for 1–2 minutes to reach optimal strength.
A wash and cure station makes both steps easy. Browse more options in our water-washable resins collection, or find compatible machines in our resin 3D printers range.
Frequently Asked Questions about Siraya Tech Simple V2
Can it be washed with water?
Yes. Siraya recommends 15% alcohol, but it can also be washed with plain water or IPA.
How long can I leave it in water?
No more than 20 seconds during washing — uncured resin dissolves easily.
Does it smell bad?
No, it's a low-odor resin.
Is it suitable for large-format printers?
Yes. Its low viscosity (170 cps) and low peel force make it ideal for large-format printing.
How long does it take to cure?
1–2 minutes under 395–405 nm UV light, with the part clean and completely dry.
Why does it crack during curing?
Usually because the part wasn't fully dry. Make sure to dry it thoroughly before curing.
Is it good for painting?
The gray color is a great base for spotting detail and priming, and its smooth surface makes painting easier.
What is its hardness?
78 Shore D, according to Siraya's technical datasheet.
Is it compatible with silicone?
Siraya states it is highly compatible with their platinum silicone, making it useful for mold making.
What's different from the previous version?
The V2 is more durable, retains the same high level of detail, and holds up better during extended water immersion.
