Siraya Tech Form 3D Printer Resin - Laser SLA 3D Printer Resin, Easy to Print and High-Precision, 405nm UV Curing Photopolymer Resin for Laser SLA/8K Capable 3D Printers(1kg, Grey)

I’m not sure if I got a bad batch of resin or if there is something else wrong, but I have not yet had a successful print with this resin. I am trying to use it on a form 2 with the standard (not the LT) tank. I keep getting various forms of adhesion errors. The first time I tried printing, I just shook the bottle vigorously and tried with grey V4 preset in Open mode. Nothing adhered to the build plate. The next time, I tried putting in a manual -1mm z offset. This time, I got adhesion to the build plate in the beginning of the print. However, half-way through the print the object came off the build plate and was stuck to the resin tray! For the next test I tried pre-warming the resin, with a -1mm z offset, and using the black V4 resin setting (which should be longer laser exposure times). This time, I got adhesion to the build plate, but the layer adhesion to the resin tray was too strong, and the print sheared in half during the print! For my final test I pre-warmed the resin, used a -1mm z offset, and went back to the gray V4 resin setting. This time, some layers did not adhere properly to the previous layers, resulting in yet another failed print. The object I’m trying to print takes about 70mL of resin, and is about 50mm in total height. It’s not a huge object but not very small either.I know it’s not a printer issue, as I have never had a failed print with genuine Formlabs resin. I mostly use grey pro resin, and occasionally use elastic or clear. I was excited to have a significantly cheaper alternative to genuine resin, but this sirayatech stuff is just too inconsistent for me to use right now. One thought is to use the sirayatech resin in genuine empty grey V4 cartridges. This way you don’t have to use “open” mode, and the form2 will make use of the heater and wiper. The downside is you can only use about 2L total per cartridge before the machine won’t let you continue using the “empty” cartridge. To continue using it you will have to either reprogram the cartridge chip (search online for how to do it), or use a “universal cartridge” replacement chip. I have ordered some empty grey V4 cartridges to test this with, and will update my review accordingly.One other thing to note is the smell. This resin has a VERY strong odor. Much stronger than any genuine Formlabs stuff I’ve used in the past. I actually got a headache the first time I used this sirayatech resin, and I have never gotten a headache from 3D printer materials in all my years working with various types of filament and resin. My form2 is also right next to a very high quality activated carbon air filter, and I have it in an area with external ventilation that amounts to about 1 full air change per hour. So I can’t imagine how bad this would smell in an unfiltered/unventilated area. Make sure you have strong air filtration and ventilation before using this stuff!Overall pretty disappointed with this so far. The price is around the right level, but it just doesn’t work for me. So far, I have used up 1/3 of a liter, spent many hours filtering resin after failed prints, trying different settings, etc. and I have not had a single successful print so far. It is not as simple as sirayatech would have you believe (they claim you just have to use open mode with gray V4 settings). I am hopeful that spoofing the machine into thinking it has genuine Formlabs resin (and thus using the heater and wiper) will help, but only time will tell (and sirayatech made no mention of having to do this with their instructions/description)

I recently got a Formlabs Form 1+ for free from my school because they couldn't figure out how to use it anymore. After fixing and cleaning it up it worked great but I really didn't want to pay hundreds of dollars for Formlabs resin. This stuff seems to work just as well and it's about a 5th of the price, so I'll be using it exclusively from now on. I just wish it came in more colors. Would totally recommend if you have a laser SLA printer and don't want to pay ridiculus prices.

Cons::- Horrible smell, very potent.- Color is more of a translucent grey than an opaque grey.- More brittle on thin prints than the standard grey resin from Form LabsPros::- 25% of the price of form labs- Prints perfect on Open mode grey v4 selected- No post-curing needed like other 3rd party resinsPersonally, if you can tolerate the smell where you work then it's a great deal. Hoping they come out with a castable for the Form. (Let me know if you need a tester :) )

This resin is great, so good that I've already gone through 10 bottles. Rarely ever have failed prints on the form 2, only failed prints have been ones with large surface areas as this resin is fairly sticky.To those saying it goes semi translucent, I realised that's because the resin has gone unmixed and seperated, shaking my cartridge before each print solved this. This resin makes some of the best prints I've gotten out my form machine

I use this on my Form2 and it's been the best. Slightly more smell than the Form or ALW resigns, but works so good and looks amazing, so it's fine.
