How fast can 3D printing get?

 
How long does it take to create a 3D model?
The printing time depends mainly on the height of the object. The model "grows" by approx. 2 cm per hour. This means that the printer needs approx. 5 hours for a 10 cm high model. It is faster to print the objects "lying flat".
After printing, the object still needs to be infiltrated and hardened. This takes 30 minutes with super glue and approx. 12 hours with 2-component epoxy resin.
The installation space is 35 x 25 x 20 cm, but larger models can be created in parts and glued. It is possible to print several smaller objects at the same time.
In which format must the 3D data be delivered?
The common formats are .stl (colorless) and .wrl (colored, textures). The .ply and .3ds formats can also be processed. It is best to send us your data via email.
What should you watch out for in 3D modeling?
The objects must be so-called "waterproof" volume models, i.e. there must be no open edges. Please pay attention to inverted normals (the normals must point "outside".)

Here is a little guide for printable models: Notes on modeling 3D volume models
But you can also send us your data, we will check it and, if necessary, support you in revising it.
Are there any restrictions on the models?
In principle, components up to 0.1 mm thick are possible, but particularly load-bearing parts, long tips and unconnected columns should not be less than 2 mm. We will check the geometry in this regard and will be happy to give you feedback.
Which 3D printer is used?
We use the Spectrum Z510 DesignMate Cx from ZCorporation.
The advantage of this printer lies in the favorable price-performance ratio of the models produced. It is also possible to print directly in color and with textures.
How does 3D printing work?
The 3D object is broken down into 0.1 mm thick layers by the printing software. For each layer, a layer of mineral powder is applied in the construction space, then the print heads (one for each color component) move over it and solidify the powder on the model areas with binding agent. Then the next layer is applied and printed. This continues until the entire model is built.

At the end, the non-solidified powder is sucked off and only the model remains. The superfluous powder can be used again for the next model without any loss.

This model is still brittle and needs to be infiltrated with epoxy resin or liquid super glue. This gives the model a plastic-like strength and can still be reworked.
