Simple (1kg) 3D Printing Resin (Clear)

Très bonne résine washable, facile d'accès aux débutants. Super résultat et super content, avec une saturn comme avec une Alkaid elle top.

Best value and save more money using water to wash. However need to cure for 30mins in a proper UV light curing station. My first model has crack all over. After some research, it was recommended to cure for 30mins which I only cure in a uv box for 3 mins. My 2nd attempt with 30mins curing time turn out really good, no more cracks.

[EDIT Aug 24, 2020 I have several prints from around the time of my initial review (July 8). For this test I printed 3 models with each resin mix: 100% Simple, Simple mixed with 30% Blu and mixed with 50% Blu. All were washed in 99% isopropyl alcohol, 20% iso and 35% vodka then rinsed with tap water and cured with a UV lamp. To date I've had zero issues with "melting" as others have reported. I used the same settings as I do for Blu (which come from the Anycubic Photon Google Sheet that is available in a number of enthusiasts groups). The 100% Simple is about as brittle as other standard resins, subjectively. The 50% mix was a little sticky after the wash/rinse for non-99% iso washes, and I didn't notice a significant difference in subjective toughness compared with the 30% mix. I did notice a marked increase in smell as I increased the quantity of Blu. ] I am a fan of the Siraya Blu and when I heard about Simple I had to find out if the low odor and clean up with 15% alcohol claims were true. I was too excited to try this and loaded up a model that has settings for Blu without really thinking about it, and Simple printed beautifully. I also found that the smell was hardly noticeable. I put the prints in my ultrasonic cleaner with an approx 20% IPA solution and cleaned them for three minutes. I was very pleased that there wasn't any obvious resin on the surface. Blu, on the other hand frequently felt gummy despite being cleaned with 99% IPA. While removing the supports they felt stiffer and more brittle than with Blu, but this resin isn't claiming to be tough. I'm going to try mixing this with Blu to see if it gains flexibility while retaining its low viscosity and easy clean up.

It turns yellow if you use a curing station. I've had good results if you wash in IPA and let it dry naturally.

The only issue I've had, was the provided Chitubox profile for this resin on my Elegoo Saturn 2 had too short of a layer time, causing fine-detailed parts to have repeated print failures. Otherwise it's a great product, with a mild smell when the hood is off the printer (it has an included activated charcoal filter inside). Cure-time seems rather long, and one of the details not mentioned in the description is the need to use a 15% IPA/85% water mixture for cleaning. You only read that on the SirayaTech website's spec sheet. But the resin is very liquid (at 24-25 degrees C), so you can also just let the print drip the excess and not have to worry too much about washing before curing.
