in The Rich Get Some Multi-Touch to Create Thier BMW on SolidSmack
OMG - what a giant waste of potential - there are so many other much more useful and meaningful applications....

EXACTLY what I was thinking. The one edifying aspect of this is the whole interactive/adpative (albeit preprogrammed) aspect of configuring products via a multi-touch device. Just wait though Heinz, once this hits the mass markets... even better interface tech.

in Would You Use It? The First High-Quality 3D Printer… On Your Desktop on SolidSmack
The last few weeks I compared almost all available RP Systems, because my boss is thinks about buying one so i can say you really need to differ!
first: ABS like for injection molding etc. is cheap but the specially prepared ABS for SLA and Printers are expensive - you really need to do an comparison on Density and Volume und get out of a cartrigde - the weight price is totally useless! And on this basis the Objects printers do pretty well compared to the other printers - although powder printers (or laser sintering) like the ones form Z-Corp are still unbeatable in that sector. Also you have to consider that printed/SLA ABS has by far not the same properties and qualities as "industrial" ABS.
second: what do u need you printer / SLA for ? for parts bigger say like 10-20cm SLA might be suffiently accurate BUT if you print out components that need to work instantly or u have small objects like MP3-Players etc or even smaller like machine components that are only like 1 cm big and have feature only a few micrometers thick then you can forget SLA altogether because their resoultion totally sucks. Small casings like for MP3-Player or mobile phone could be finished but not real small machine parts etc. If you also consider the machine, tools, supplies and worktime you need to finish SLA parts the you run costs way lower even in the middle run - and you are faster and thus flexible!
Another feature which is hardly or impossible to manage are micorstructures like this (http://3s.addfabb.com/index.php?lang=1), which will gain a lot of importance in the future!

Differ hmm
I think not~!!! You say that sla is not accurate in small part design especially for small machine parts?
Have you ever had a small part made from an SLA machine? Because I have...I.E. gears racks...which are some of the most res tolerant important apps as they must maintain the original cad models integrity right to the angles specified.
Surely there are other uses where the sla part may not match the cad file.
Yes there is a difference between industrial abs and the pre-loaded abs cartridge material. But, you mentioned powder based 3D printers....lol.
Powder based 3D printers also have costly pre-made material costs. But, there are " OEM " remixes for powder based 3D printers that quite frankly are not difficult to formulate.
The same applies with the Dimension abs 3D printers. Thus again I say that the cost of using an abs 3d printer is very much under that of any powder or sla 3D printer.
To make a point just because your car was designed to run on gasoline, does not mean you have to run it on leaded, unleaded....lol.
An engine will run on water I.E. hho or straight hydrogen as well as bio fuels cooking oils and various other properties; as for the maintenance and longevity for using non-recommended formulations depends upon your mixture solution.
This same idea can be employed with any 3D printer but the cost of abs compared to that of the materials of sla & powder based machines is great.
On the z-corp 3D printers....I simply don't like the way that this company does business on the management/corporate level. Not to say the distributors but the wild price flucuations from one state to another.
And, zcorps unwillingness to allow potential buyers to purchase machines from other states than where the machine will reside. The responsibility of maintence for a machine is upon the owner not zcorp or it'slocal distributor who wishes to charge $ 15K or $30K more than a distributor for the same package in another state or area outside the local distributors area.
The unwillingness to co operate from zcorp to me says everything about the company & their products.
Fortunately, there are many other manufactures to obtain 3D printers from and the list continues to grow each year.
