Stratasys didn't give any details on the 3D scanning software used. But a dental lab I spoke to that makes single-piece crowns and bridges, not models, using a different vendor's 3D printers mentioned to me that those printers talk to STL files, apparently a standard file format in 3D printing now, at least for dental applications.
Thanks, JimT. We're already on to these. MakerBot has been around quite awhile, as has 3D Touch. The latter was made by 3D Systems, and is now listed on its "discontinued personal printer" page: http://cubify.com/legacy/ DN has covered EnvisionTec as far back as 2008: http://www.designnews.com/author.asp?section_id=1386&doc_id=209213 http://www.designnews.com/document.asp?doc_id=228209 http://www.designnews.com/document.asp?doc_id=229043 http://www.designnews.com/author.asp?section_id=1392&doc_id=211771 Interesting question about pricing strategies, but we'll never know.
Thanks for sharing that 3D-Touch was a 3D systems discontinuation – I was not aware of that, at all, and was further mis-led by an associate who is trying to market these machines to buyers. Apparently, he has a small quantity of them and is offering them for sale and support, at $3,900 per system. It seems even more un-attractive now that you've disclosed its discontinued manufacturing status. Thanks!
JimT, you're totally welcome. I discovered that fact by Googling to find the manufacturer of 3D-Touch. Although the number of different printers has gotten large, the number of 3D printer manufacturers is still very small.
3D-Printing have exposed denstists to the digital world. Now denstists can replace bulky, physical gooey silicone models with small digital files. Store all of case files digitally, for as long as they need.
I am a dental technician. We use a scanner from 3shape who specialise in medical scanning.
The scanning can be done intra-oraliy or at a lab with a stone model.
From there with help from 3shape's cad design software we output in a range of formats depending on the manufacturing unit.
For crown and bridge dental restorations the printers must be accurate to 35 micron(mm) or better. The main printers in our industry at the moment are Envisiontec, 3D systems, Objet, Solidscape, and Asiga.
In my opinion this market is changing extremely fast and the labs and dentists left behind will find their work decrease dramaticaly within 5 years.
Yes Elizebeth you are correct initially i also used to consider that 3D printers are being used by hobbiests only .But after getting information that they are used in dental and automobile labs i am too astonished to see .Using 3D printers in digital labs will help make the models in less time, more sophisticately ,more neatly ,no special knowledge of computer is required this device is user friendly it eliminates the concepts of large racks in the dentist clincs having files of all patients instead by using 3D Printers all files are digitally stored in the computer in CAD format .It is less space occupying as well.
labwa, thanks for telling us about what this is like on the ground. Your experience reinforces what I'm being told by analysts and manufacturers about how fast the dental industry's use of 3D printing is changing. I just wish my own dentist was paying attention and could become motivated to change labs to take advantage of this technology.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Alcoa has unveiled a new manufacturing and materials technology for making aluminum sheet, aimed especially at automotive, industrial, and packaging applications. If all its claims are true, this is a major breakthrough, and may convince more automotive engineers to use aluminum.
NASA has just installed a giant robot to help in its research on composite aerospace materials, like those used for the Orion spacecraft. The agency wants to shave the time it takes to get composites through design, test, and manufacturing stages.
The European Space Agency (ESA) is working with architects Foster + Partners to test the possibility of using lunar regolith, or moon rocks, and 3D printing to make structures for use on the moon. A new video shows some cool animations of a hypothetical lunar mission that carries out this vision.
