How does ExOne’s Digital Part Materialization process work?
How durable are 3D printed components?
What is the surface quality?
What kind of tolerances can you meet?
ExOne sand printers can achieve printing tolerances of +/- 0.3 mm (0.012 in). ExOne metal printers can achieve accuracies of +/- 0.13 mm (0.005 in) in components under 75 x 75 x 75 mm (3 x 3 x 3 in); +/- 0.25 mm (0.010 in) in components up to 250 x 250 x 250 mm (10 x 10 x 10 in); and +/- 1.3 mm (0.050 in) for the largest components up to 780 x 400 x 400 mm (30.7 x 15.75 x 15.75 in).
Can more than one part be printed simultaneously?
Yes. The software will allow for as many parts as can fit within the build box, and each can be different or fully customized. This maximizes time and minimizes waste. It takes as long to print one part as it does to print multiple parts in the build box.
Are other materials available?
Yes. Several metal options are currently in development. Please inquire about your specific needs and ExOne will determine feasibility.
Why are so many companies choosing ExOne for digital part materialization systems and services?
The digital part materialization processes offer design and manufacturing freedom previously unachievable. ExOne systems are robust and reliable, running around the clock unattended.
For contract services, the cost to produce prototypes or low volume pieces is significantly lower than alternative techniques. ExOne support technicians are dedicated and responsive to customer requirements and deadlines.
What is the advantage of choosing ExSource Contract Services over other additive methods such as SLS?
For contract services, the cost for ExSource components is significantly lower than other additive process shops.
I have no 3D design experience. How do I get started?
What is the best 3D modeling software to use?
There is no “best” 3D modeling software. However, there are a lot of really good software packages such as Rhino, Maya, and SolidWorks. But, CAD software such as AutoCAD and Pro Engineer also work well for 3D printing. If you’re just getting started, you can try SketchUp or Blender, and both can be downloaded for free.
What types of files do you accept?
You can upload .STL, .STD, .IGS, .MODEL, .3DS, .MXP, .OBJ, .WRL, .3DM and .SKP file formats to ExOne. If you have a large file, or a number of files, you can also use the RAR and ZIP formats to compress them and upload these to us.
Are my files treated confidentially?
Absolutely – and we can execute formal nondisclosure agreements for further protection. We will never share customer files without written consent.
What if my 3D model contains “errors”? Will you fix it?
Each 3D model we receive goes through a comprehensive evaluation process, which will pinpoint any errors in the file. You then have a choice of making the adjustments yourself and resending the file, or having our qualified 3D designers make the necessary changes for you.
What is minimal wall thickness and level of detail?
How big can I make my model?
ExOne produces some of the world’s largest 3D printers. For metal and glass our largest build area is 780 x 400 x 400 mm (30.7 x 15.75 x 15.75 in). For sand, our largest build area is 1800 x 1000 x 700 mm (70 x 39 x 27 in).
How do I get a price quote?
How long does it take to print an order?
The standard lead-time is 5-15 working days, depending on the complexity, material, and finishing of your order. Most orders are shipped out within 10 working days.
Can I order from any of your facilities?
Yes. Each of our facilities has the resources to take your order and forward it to the appropriate location for processing.
Do you ship worldwide?
Yes. ExOne operates facilities on three continents and ships worldwide.
