[QUOTE="Hal2a, post: 19106, member: 1003"] I have recently purchased a 3 shape scanner and have just got back some test cases. I sent out for milled wax patterns, printed wax and zirconoa copings. The zirconia fit great. I would have to say as good as the Lava that I used to get. The milled wax had margins that would fit in places but rough margins did not come out very accurate.Also the anatomy could be more detailed and the surface did not mill very smooth in spots. The printed wax looks good, the anatomy was reproduced accurately, but the margins were rounded. I feel the printed is my best hope for a coping. I will just have to go around the margin with wax. It should only take about 20 sec. Its scarry because when I contacted the center that printed the wax, they told me alot of labs will go ahead and use the copings with rounded margins with out adding to them. Its extremely cool technology and if it can cut down on some of the "grunt work" and let me concentrate on ceramics, then mission accomplished. [/QUOTE]
