My recommendation would consider the type of application and money available
to spend... For prototypes and castings? The Z-Corp machine is fast and cost

Material is strong enough for prototypes.

Some post processing required... Z-Corp machine (IMHO) requires the least
amount of post processing.

The customer support from Z-Corp is EXCELLENT.. In short I can not say
enough about thier staff!!

Yes.. STL. If my memory serves me correctly, they are working on an upgrade
with other capabilities!

I have ran the *&^% out of the machine at times with excellent reliability.
Without consideration to human err and when set up properly, the machine
will print a good part every time, the first time.

I like the Z-Corp machine because we can make castings (very quickly) from
the parts printed off of the machine.

Subject: 3D Printers - recommendations please


Please forgive me if this subject has been recently covered -
I have just rejoined the list as I'm looking for help.

I am currently looking into the purchase of a 3D printer
eg 3DSystems ThermoJet or ZCorp Z402.

Can anyone with experience of using a 3D printer give me
some feedback including the following:

- which 3D Printer do you recommend ? why ?
- is the material good for prototype use ie strong enough ?
- is post processing necessary ?
- do you get good customer support ?
- what file format does the printer accept ? (.stl ?)
- is the printer reliable eg does every build work 1st time ?

Any information you can give me will be much appreciated.
I need to move quickly on this !
