I just ran across this from Amann Girrbach. Does anybody know of any other manufacturers which might be offering a similar product launch. Is this stuff any good?
As far as I know it's proprietary to Amann...
Sintron rules. I couldn't begin to tell you. The fits are unreal and it's crazy simple. Once you use it, casting Np seems like,..well,..retarded
I just haven't had any fits of milled NP frames that I was happy with. The Ti frames seem to fit much better, but it isn't real user friendly with porcelain application. I would consider NP in certain situations if the fits improved. It would be great to see a comparison between the soft-sintered and the hard-milled.
It takes about 12 minutes on average to mill one unit of Sintron. The fits are consistently perfect. The CTE is the same as non-sintered. The cycle on the Argotherm takes 5 hrs total from start to cool down. You can fit 20 units in the pot for each cycle. We can fire at 8 am, 1pm, and 6pm (overnight) which equals 60 units possible per day with just one oven no problem. Material cost @ 5 bucks per unit.Tank of Argon is @ 35 bucks to fill and lasts us about a month Sintron is as soft as wax. CrCO is extremely hard but it is not a problem for a super robust industrial machine like a Haas or a Datron.
Trying to do solid block CrCO on a tabletop style mill is a no go .. they just won't take that kind of punishment for long. The only metal that these machine were meant to cut consistently are soft aluminum blanks used for making molds and small novelties like "tin soldiers" and stuff
It is true that he specialized oven is not cheap but if you're doing 10+ units of NP per day, the additional cost for the Argotherm will quickly return and then it's all taters and gravy baby
Here's my take;
If your broke keep waxing and casting in your garage
If you are low on dough, buy a scanner and farm it out bro
If you want to hate yourself, buy an inexpensive re-packaged jewelry mill
If you have some money buy a robust, versatile dental mill (see the Ceramill motion 2 if you need to know what one actually looks like)
If you have the big bucks and you actually NEED one of those big industrial type bad boys then go for it (eg. One piece Ti abuts and bars for labs)
Printing, for me anyway, is not helpful

Out of curiosity, can you sinter ZR in that same oven, or is there potential for contamination etc.?
