Success - First prints from the Phrozen Sonic Mini 8k

Hey all,  thanks to everyone for your comments in the couple of other recent threads.  Turns out that sanding the WhamBam plates with some #800 paper was enough to give it some tooth for the prints to stick to.   Here are a couple pics of the first few test prints with some N-scale parts, first up are some concrete grade crossings and 12' Jersey barriers:




And here are a couple of car stops:



 More to follow, for now these seem like a pretty good start.  (Off to the paint booth....)


Edit - sorry, these aren't really the greatest pics to show what the printer can do..... I am going to have to look into getting a macro lens for the cell phone camera.


Cheers,
Ed

are the grade crossing files available online or did you draw them yourself?

I did my own, based on some proto .pdfs that I found online (with some width adjustments to allow for model flangeway clearance).

Good idea on the grade crossings. I’ll have to rummage around in the NP drawings and do the same. Glad your printer is now working; be prepared for it to consume far more time than you thought, although it will open a world of possibilities.

Hot (almost) off the printer: A few of the car stops and bumpers, this time in O scale (next to N scale for reference).

Isn't the future wild?

Wild indeed.

Here are a few more.... first, a set quasi-functional (the knuckles pivot a bit stiffly, and do not lock closed) of AAR couplers, in 1:48 scale, next to some (fully functional) Protocraft couplers for comparison (note the Protocraft have the compromised, Kadee-compatible shank):




And here is a batch of @GaryHinshaw 's N-scale replacement car ends for the Atlas 17.6k corn syrup tank car printed in 8k -- along with one in 1:48 scale, because, well, why not?

Wow Ed - that's really cool!  The 1:48 detail is amazing!!

I've been contemplating an 8K printer, and IIRC, you had a Photon Mono before.  What is your impression of the difference?  The grate detail on the N platforms seems a wee bit softer than I might have expected.  For comparison, here is a shot of a (painted) platform printed with my Mono using 51 μm voxels:



Do you think I should go for an 8K?

Gary, I'm pretty sure you would not be disappointed, and I'd expect that you'll find more and more ways to use it over time.

For me the 8k has re-kindled my interest in 3D printing. (Exhibit A, note the number of prints I have made since I started with it, much more than the Mono.)  I've always thought of the Mono as an entry-level device, and while there certainly are some things that it does well enough, still it has its limitations.  My use of it had tapered off, and I don't think I have printed anything on it in the past year or more.

With the 8k I think I have only scratched the surface of the possibilities so far, and I expect that I can use to print the kind of parts which otherwise would have been only marginally acceptable (to me) if done on the Mono.  There is a long list of things that I want to try out (scale spikes, anyone?).

BTW I think the (apparently) 'soft' looking details on the N platforms is more a matter of the camera than the actual parts.   Under magnification they look fine to me.  (I really need to get a better macro lens for my iPhone camera ;) ).

Have you taken any accuracy measurements from the 8K and compared them to the cad model dimensionally?  That is the most disappointing thing I have encountered with my Mono.

Have you tried the knuckle couplers in N yet?

No, I wasn't really thinking to use it for any sort of precision application.

I think someone else is doing something like that....?   ;)
