Material-Details: Copper Datasheet

 

Copper is a material which is used for thousands of years. Due to its good thermal and electricity conductivity,this can industrially produce usable components.
Copper is a cheap and very detail-faithful way to realize pressure metal parts by means of 3D printing.


Advantages & disadvantages

Advantages
  • Precious
  • Abrasion
  • Detailed and extremely clean in printing
  • Very good permanent availability
  • High stability
  • Very conductive (electricity and heat)
Disadvantages
  • Not all possible shapes

Material examples


Price calculation

Copper is calculated in cm³ berechnet. Always polished copper is shipped.
An additional handling fee advantages model is necessary as much hand work is involved in manufacturing.

  • 30 € / cm³

Typical usage

Copper is often used for the production of miniatures, coins or medals, but also applications are plug connector or heating pipes realized with copper.


Technology

Copper produced in the so-called "lost wax" process.
While your component is printed by SLA in a special Castingwax and then classic cast.

The procedure:

Your model is disassembled by a program into individual layers of 0.05 mm.
Now a plate lowered into a bath of wax casting.
On this plate starts now a UV laser to the contours and shapes of the parts 'draw'. At all points in which the laser meets the Resinbad, the material hardens.
Now the build platform lowers to a layer thickness down and a slide allows for new material on its surface.
This process is repeated to layer by layer until your component is finished.
During the construction process your component rests on the insulators.
These are manually removed after the printing process, and sanded.
Your part will be placed in a mold and cast in a molding compound. After this mass is cured, the printed part is melted off (hence the term 'Lost Wax').
Now, the resulting cavity is poured with molten copper. Thy portion is broken after curing from the mold and the sprue is removed. Thereafter, the further post-processing steps are carried out as polishing and grinding.

Additionnal information

  • Forms such as "Ball in ball" are not producible.
  • All forms of "floating" are not feasible (for example, the links of a chain)
  • Copper oxidized on contact with air. Our PU protective layer slows this effect, but can not completely stop it.

Coating 3D Printing

 

Of course, we can coat parts made of Copper on request specially. This, however, unfortunately, only trought a manual request

  • We can coat only parts of 10 x 10 x 10 mm to 600 x 600 x 600 mm. Larger parts on demand.
  • Handling fee 12 € / Order
  • Hand electroplating .
  • High Resolution from 1 µm
  • Possible coatings..
