I am trying scan impression and print model and pour second model(prep side) and check contacts and margin. I think it is best way to check both and save time at model room. anybody tried yet ?
my goal has been to scan imp, pour secondary model to check contacts....and right to crown fabrication. no printing of models needed is my goal

FabPro:
https://www.3dsystems.com/3d-printers/fabpro-1000

Cheaper 3D systems unit with great accuracy for models. Build size not the largest.

Structo runs around 40k USD. Resins about 200 USD.
I am interested in your thoughts on the Fab Pro 1000. It has a nice price and is fast when compared to other $5000 printers. It supports Nextdent SG and Model 2.0 resins so it might be a good fit if you just want to print models and surgical guides. The 5100 is $10K but does a lot more and its crazy fast.

I heard good thing about this Nexdent 5100 printer. but i am not sure about it's reliability. I am afraid if i having issue with printer later and the tech support does not how to

handle. they might say "This is first time it is happening and have to investigate" so they connect me to specialist and they don't have solution and i am stuck with machine

for days and weeks without using it. if they can send me a loaner machine, then i would be very lucky person. it is from my personal experience
You make a valid point but the 5100 has been in alpha and beta testing in a wide range of labs for about a year. As issues were found the design was modified and improved. It is definitely not going straight from an R&D facility into the market. There has been a lot of QC along the way. The head of the engineering team lives and breathes quality control. This printer is a work horse.

Just sharing my experience here….. For last couple of months I’ve been testing this workflow to see if it will work for me…I’m a one man lab so I do everything from models, design and finish. (I outsource the milling) I’m using a Medit scanner ( with a 3-axis arm.) With that and their scanning software, it’s excellent at scanning impressions. Then designing In Exocad and using the Model Creator module for the printed models. (I’m also outsourcing the models, for now…)

I had to figure out how to print models from most of scenarios given to me from each client.

Scenario 1: IOS scan, duh, Obviously a no brainer for printing a model ;)

Scenario 2: Triple tray impression. The 3-axis arm will do upper + lower + bite in 6 minutes., then design restoration/model, done.

Scenario 3: Rigid tray impression (quad or full arch) and an opposing model + bite or bite impression tray. There is a scanning strategy to do all of this and align in the Medit software as well. ( just takes an extra few minutes for the bite tray) If the bite is not in a tray I just mount it in one to put in the 3-axis arm. Scan, align, design restoration/model done.

Scenario 4: Upper + lower single tray impressions + bite tray ( or bite, just mount in a tray.) Scan, align, design restoration/model, done.

(Obviously with 3 & 4, you need some kind of bite. I have eventually talked most to send me a bite tray impression so I don’t have to mount it in a tray for scanning.)

Scenario 5: Implant impressions …these are the only ones I’m still pouring for now as there is no scan strategy yet for this. We need some sort of “reverse” scan marker to mount on the impression post + a library to match in the design software. I’m sure eventually someone will come up with something…

So far it’s working pretty good! I’m only pouring implant impressions....no remakes and no complaints on marginal fits. (Had some high bite complaints in the beginning from the usual suspects, lol) but have compensated in the design phase for them and all’s good.

All in all it is actually saving me time as I’m “dialing” it in. (Plus, I hate pouring models!!)

The models I design are simple, basically solid ( hollow) with no removable dies. A “crown holder” of sorts, lol… to check contacts and occlusion (like a solid pour)

As mentioned numerous times modeless would be an ultimate goal, but some guys just like to have something “traditional” to look at in their hand…

I’m looking at printers now, and have a test model that I have sent out to a bunch of printer companies. So, I’m ready to buy one of them fancy model pourin’ technician machines!! Just waiting for that “new” one to come out , Glenn :)

Larry this may be what you are looking for, however I am not sure how easy it would be to get the library.
Basically reverse scan bodies.

If you are the tinkering type you could make your own library with regular or customized analogs using Implant Editor.

Thx 2th..Excactly! I was thinking that something like that would work! Obviuosly ZZ has done it, Unfortunately unless you have a ZZ system you can't buy from them.

<<<<If you are the tinkering type you could make your own library with regular or customized analogs using Implant Editor.>>>>

(That might be above my " tinkering " pay grade, lol!)

I'll bet some 3rd party Implant component CO will come up with something eventually. something like anextension that fits on the impression post that would use their present scanbodies + an addition for that in the library

We are a larger lab compared to most that I have visited and we run 3 Asigas PRO2 series printers and it handles our Models, surgical guides and dentures. We run different materials from different companies without any issues. They are fast and extremely accurate. The service that we have with this has also been top-notch and always available to help if we need to calibrate a new material, but outside of that the machines are our workhorses.

scanning impressions not consistently accurate enough to use as my business model
will have remakes. Margins are very difficult to read even when stone pour is perfect and clear.
So I quit doing it.

BUT a printer has become invaluable part of my lab !!!!!!

I have asiga and love it.

I use the Nexdent resins for provisionals / prototypes. and for digital diagnostics I print with whipmix model resin.
Print all my frames to press or cast. Super accurate fits and margins.
Saving me a ton of time and offering services I could NOT offer before

Yes heard great things about your new printer, lots of prelaunch hype and looks like a excellent price ?? Under 10 grand ??

It's a pretty exciting product so there has been a lot to talk about. Now we are very close to getting past the talk and delivering a great printer with a wide range of resins and a great reseller channel.

BTW, I also requested and received approval for DLN sponsorship so stay tuned and I will share more when I can.

Al, Yes sir I hear ya!! Definitely a printer is my next equipment purchase. I have a strict business model as well. Fortunately Most of my guys do take nice impressions.... but not all...Obviously if it's that bad I'll pour to check and have them re-impress!!

Not sure what scanner and software you have, but luckily with the scanner I have and it's software scan paths & strategies, the impression scans are very good . So far it's positive...very few remakes.( I have actually received comments on how nice the marginal fit is. go figure... (Or course that with the ones that take the best imps, ;-)
If it's clear and I can read the margin in the impression the scanner will too. Sometimes .."ah-hem" we have all done a little fudging if it's not too bad, lol!
You can, and I have had to learn how to do that with impressions in "reverse" with scanning wax and/or "free- form in the design phase, lol!

I am BETA testing both systems now.
Vats are expensive for 5100, and prone to tears.
Fabpro is slower , but quality is great.

Did you print models on the Fab Pro? How many were you able to fit and what orientation did you use? Horizontal, vertical or angled? Full arches, quads? Do tell! :)

Printing denture base, film is not supported in center. Large cross sections cause stress in center, result in tearing of film.
3D_MAN,
I sent you a PM to try and learn more about this. You replied that you reported this during the BETA test but the BETA logs show no reports of torn membranes from any BETA testers. If the membrane had torn during testing you would have needed another membrane to continue testing. Our logs show only two replacement membranes shipped to BETA testers and both were due to damage during shipping. None were reported damaged during testing.

I also contacted our engineering team and they conducted several tests today with large cross section files. None of the tests resulted in a broken, torn or punctured membrane. If you would like to reply to my PM with your contact information or use the contact info I included in the PM to call or email me we can understand exactly what you did and try to replicate it.
