Is the Resin1 the gray?

The grey is Phrozen RPG resin.  The black is the Resione K+

Wonder if that Resi0ne K+ wiould work on my DLP.  That print is CRISP and looks a lot like the Anycubic DLP black resin.

I don't see why not--it's UV cured-- worked on the Phrozen Mini 8K.   It took me a few rounds to calibrate it using the "cones of calibration" model but wasn't too bad.  Does your DLP give basic settings for various resins?  The Phrozen does, but still took me a while to dial it in by changing the exposure time vs what someone had published.

How far off were your end settings from what the manufacturer lists at Amazon (they have a short list of exposure times, etc.) - within those bands or slightly outside? Still debating here if I want to give this resin a try.

Naw, my settings came from another DLP user and those have been great.  I'm really happy with my current settings on the AC DLP resin, so I would start there if I got some.

I didn't use the ones on Amazon (I didn't even see them).  Here are my settings on a Phrozen Mini8K.  I had to lengthen the exposure time from the one I downloaded -- I think originally it was around 2.9 sec..

Thank you, appreciate it.

This Z-scale 50' gon is the first test of a car I did with the Resione K+ resin.  The results?  A+ (sorry for the pun).

Those are free-standing ladder rungs, 0.14mm H x 0.30mm W  Using the old RPG resin the rungs would always end up with a bit of sag/curl.   They are durable enough for handling.

And the sides are plumb straight, and no sag (length-wise) to the car at all, which I was getting as well.

Wicked good, Jesse.

I dove in on the resione K+ resin, and I really really like it.

I've been working on upscaling my HOn3 D&RGW kits to Sn3, and used that testing as a platform to try the new resione K+ in lieu of my mix of Phrozen 8K and Sirya Tech Tenacious.

Initial observations:
Smell - Its smelly, but like in a very intense pinesol kinda way, and generally only when the machine is running and the stuff is being disturbed.
Settings - Settings I was using for the custom mix were way too short for .020 layer heights. I've settled on 4 second exposures and that seems to be about perfect
Supports - Same support settings I was using are working well, even in larger scales. I have my supports dialed so they can generally be removed without tools.
Warpage - The warpage for sure seems to be better than other brands ABS type resins, it is on par if not slightly better than the custom mix I've been using to good sucess.
Finish - Details are sharp, surfaces are smooth, on par with with phrozen 8k.
Flexibility - Even after curing this stuff stays flexibile, better than ABS resins I had used in the past. Similar to my custom mix, maybe slightly more flexibile.

The one item I and still tweaking with is how it works for grab irons/brake rods/etc. the stuff comes out of the printer a bit wavy. but after washing and allowing it to dry things straighten up. And it seems that after 24 hours things have returned to the "normal" shape whille still be flexible enough to not break off.

I like the stuff, the added cost premium over Phrozen 8K is worth it in my opinion, I will probably change over to this resin as I work through the rest of my custom mix.

Impressive!

In re. the Resione K+, I should've noted my layer thickness is .030 mm.

The "wrinkled grabs" observation is spot on--I find a good 24 hour drying period allows them to return to normal (shrink a bit).  In some cases you can print them on the model, but I have had success printing grabs separately and attaching (with pilot holes designed on the body). 

Here are grabs/railings for a Z-scale SP Vanderbilt tender, these are 0.22 mm diameter:

Same is true for window mullions...  A lot of the time the parts come off the printer a little wavy.  I put them on a drying rack above our furnace for 24 hrs or so and they shrink and fully straighten out. 

I use either 100% Siraya Tech FAST or a 75/25 blend of FAST and BUILD.  I find that blend is a little more resistant to brittleness, warping and form taps a little better than FAST by itself.
