We've been working closely with BEGO and taking a serious look at BEGO Ceramic Resins for quite a while now...
we really like what we are finding..
I do believe BEGO is the Global Leader in printed ceramics, and with good reason. Many of you who work with a variety of printed ceramics should notice "working" differences between them. The first thing we noticed about VarseoSm Crown Plus and VarseoSm Teeth is that if feels "more like" e.max "at the bench" than other ceramics. For starters, the binders are mostly responsible for the overall strength of the crown, the fillers and binders effect the wear.
While VarseoSm may have a slightly longer print time, it's cure time in a Curie is 2.5 minutes, which lowers the overall time significantly if we compare other ceramics light cure cycle times. What this also means is you are working with a much more stable product off of the print bed.
and here is another major benefit...
when prints have a chalky appearance, it is because the binders have been washed out by excess processing. With BEGO products, we have a slightly longer print polymerization time meaning the print is more stable on and off the print bed. the post processing is cleaner and requires much less alcohol (more on that).
the processing of these products is so much easier and foolproof... a few minutes in an ultrasonic and the surface of the restoration has a nice "mechanically retentive" surface and an intact "binder" surface with an equally important Chemical Bonding Layer that is inherent in all 3D prints. (also more on that)
Huge Note:
The typical "sand blasting" in the final step of the instructions has been removed from the processing instructions for TriniQ. this is important (also more on that)
Now on TriniQ
As with all the BEGO ceramic products I feel like I'm working with a "dense" product, less prone to IO staining.
While hand polishing, it also takes a heavier hand to polish BEGO over others, but with TriniQ it takes even "more". i love the hand polished look of TriniQ as well.
Stain and glaze is no different than any other Ceramic...
for Shofu Lite Art, Palette, and other "paste" stain systems use a nitrogen cure. Glycerine is NOT substitution and does not cure the OIL surface.
Optiglaze color is a great system if nitrogen curing is unavailable. I have yet to test the Vita kit.
I'll post lab day links, and they will have some Pretty Incredible People at Lab Day you will want to meet!
We have been working with products prior to launch for quite some time now, and many of these products are still moving toward final validation.
here is a quick peek:
When a bottle of resin comes in it typically has processing instructions to some extent or instructions that can and have changed. We typically have an evaluation sheet with specific instructions or expectations, or parameters for an evaluation.
We load a clean vat of resin, various "indicated" structures, and structures that push the limits. With access to the Ackuretta test server (I'm hoping they grant engineering access) we can test new materials still under validation.
We calibrate the Z axis and do a test print with a different vat of material. Next we clean our plate and switch out the vat.
Once we start printing we will keep going until the material is gone. This is typically a Friday morning to Sunday night of endless printing.. we print until the small build plate doesn't have a drop of resin to pick up. Now we are talking about countless calibration checks and vat-clean cycles.. room and build plate temperature is adjusted and prints of various layer builds are evaluated along with other ceramic prints.
Print failures are evaluated, and checked against a different material vat test. Meaning an exact print in a different ceramic material to check for a print failure. This requires a large build plate of prints in most cases (this also gives a test replica for cross evaluation.)
All prints are left unprocessed, wrapped in a paper towel, bagged/labeled and put in a dark drawer until all the printing is done.
prints are now post-processed in a variety of ways, following the mfg IFU's
and also minimizing or removing a step from the processing instructions..
Products are bonded together and deconstructed and evaluated.
They are also stained/glazed and /or polished with an overall handling of the product for full evaluation.
