phrozen High Temp 3D Printer Resin [TR250LV], Functional Resin HDT80 °C 405nm DLP LCD UV-Curing Photopolymer Resin for Prototyping, Ducting, Molding, High Precision Printing (1KG)

Unlike many other resins that advertise high HDTs, this one actually holds it shape well when exposed to high temperatures (we tested in a hot car in the sun and in an oven). The color should probably be labeled silver, rather than gray, as it's fairly close to white. I would say that fine details are below average compared to most resins. I used 2.8s/layer on the Uniz IBEE (mono). Be sure to clean and cure the parts quickly, these parts seem more prone to warp than normal. The biggest downside for our purposes is how hard this resin is; it's glass-like in its rigidity so don't expect any flex, bending, threads, snaps, or anything of the sort. It will just fracture or break. To counter this, we mixed 2-parts this resin with 1-part Additive Plus's black Flex resin. Mix well; poor mixing caused a failure in one of our tests. The result has almost perfect qualities for functional parts, a nice balance of hardness and toughness with high temperature features. This mixture took a little longer exposure time that most functional resins we've tested (3.2s/layer on an IBEE - most functional resins take ~2.8s/layer).

Less odorous than standard resin of other brands Tougher than standard resin of other brands, I dropped a few prints and surprised they didn't break. Prints just as good as standard resin. The limit of heat resistant is not tested but it is definitely better than standard resin. Great for automotive use prints.

Very slow printing but well worth the wait. Excellent resolution, strong!!!

I got this resin to print parts for products that would warp during shipping with other resins. For this purpose it works quite well. Print quality, print speed, and heat resistance are all great for a 3d printing resin. Also the prints are reasonably strong and not excessively brittle. However after letting the resin sit in the vat for a fairly long time the pigment separated out from the resin and settled on the bottom. Additionally the post processing recommendations are lacking proper numbers for curing stations. It would also be great if this was made available in clear or other colors in the future.

This is one of the only "high temp" resins that I've been able to use inside of an engine bay. Everything else that I've used besides FormLabs resin (that costs about 10x more) hasn't been able to withstand the heat generated when I was fabricating automotive parts. I would highly recommend this resin

Tool HARD par*t s

Works in Arizona hear

This review is for the Phrozen Functional Resin - TR250LV High Temp Resin in 1KG size. This has a heat resistance up to 120c which is 248f, pretty impressive. This is the exact resin you want to use for outdoor projects or even inside of a vehicle or even in the engine bay where you expect the heat to be an issue for you with normal resins. The color. This is listed as a black resin however in the bottle I received the liquid was grey inside. The bottle says it is TR250LV and all that, it just seems that either what they consider black is very very light or there is an issue with the coloring of this product. My one and only complaint about this resin is that it is very brittle and hard. Taking off supports can sometimes be a challenge but this could be my settings too. It may be worth mixing in a little bit of a softer resin to promote this to work better for my use case but that may hurt the temperature resistance numbers. I will need to do more testing. Overall I was very happy with how this resin worked. I used the normal base settings for my printer and did not adjust them at all and it printed as expected. I used this to create a functional part for my car. I made mirror caps for the outside and they have lasted almost a month now sitting on the car outside. So far everything is going very well but I will update this if that changes.
