Frequently Asked Questions: Stereolithography

How accurate can the prototypes be produced?

Our equipment builds up the prototypes in layers of 0.10 mm using a laser with a diameter of 0.25 mm. This results in an accuracy of +/- 0.10 mm within the range up to 100 mm. In high resolution mode the layers measure 0.05 mm and a laser with 0.075 mm in diameter is used. This mode allows production of prototypes with an accuracy of up to +/- 0.01 mm.

How durable are stereolithography prototypes?

Elastic modulus: 2500 MPa / tensile strength: 71 MPa / tensile elongation at break: 12,5%.

How is the surface quality?

Standard: Surface roughness class 18 (according to VDI 3400). For certain requirements (e.g. transparent casts) STL master models can be polished.

How do you produce prototypes that exceed the size of the production chamber in the machine?

These prototypes are produced in separate parts which are then joined together.

How fast works Nobitec?

The shortest possible period of the data transfer up to the receipt of the stereolithography piece amounts to 2 working days.
