Bridge printed in less than one hour, cured in 5 minutes, dropped onto model without adjustments, few hours in technician's hand and patient received a next day long term temp. OnX Tough 2 is technically advertised as a final material, but due to its monolithic nature, we're using it for long term temps. We found we needed to use their A1 and adjust it to get close to A2 (the A2 shaded resin comes out a bit too orangey). Not perfectly matched, but for the amount of time it took to produce, we're impressed with the Sprintray Pro 55 S and the OnX Tough 2 resin/workflow.

Interesting. Let us know how well it holds up. We mill ours out of PMMA and they hold up real good.

We do the same, I'm curious to see how some of this all-on-x printed material holds up as well.
 
What are you using for gingiva? It looks good.
 
You can use the GC stains or the Rodin Pallette
 
Good on you for using these new "we can say they're ceramic because there's at least 60% ceramic filler in there" resins for long-term temps, btw. Promoting these as replacements for conventional subtractively-manufactured materials has always struck me as a questionable move, as they're definitely not the mechanical equal of milled restorations, and their long-term performance has yet to be demonstrated- but labs are just gonna see this as an opportunity to make permanent restorations faster and cheaper but for the same price point. We use Rodin Titan for long-term temps but not for anything permanent for this reason.

I see your point, but when the FDA comes down and classifies these as ceramic printed "permanent/definitive restorations" makes for a difficult conversation with a Doc who wants to do them. You follow the FDA or do you disagree with the FDA and not offer it...the life a lab lad these days.
 
I just manufacture whatever they ask for. I'll leave the selling to the sales reps. I'm just fortunate to be able to use each resin and I enjoy keeping up with the technology
 
I haven't had great success with onx tough 2 being long term. Fit is good, looks good, The strength/durability almost always isn't enough. Especially in the screw channels. There needs to be a longer screw with a bigger head. Some people are using the ASC screw to do them.

What are you using as a curing unit?
 
Any one having problems printing AOX denture on x though 2, in sprintray p95? I keep coming across problem of screw channel not being wide enough or not printing completely. Any feedback would help.

Could be an issue on the design end. What kind of screw are you using?

Not using a P95, but I ran into this issue using a vortex screw early on. Their default material settings has their screw channel offset at 0.00mm which obviously won't work. Bumped it up to 0.10mm (or maybe 0.010mm) and haven't had issues since.

We are using S.I.N screws.

Don’t have experience with those, but I would check the offset in the design software. Make sure it’s larger than 0.00mm.

Confirm your design is fine on that side, then check out the printing strategy.
