Why 3D printing?
Founder Daniel produced the first prototypes of the Bookhoover using his own 3D printer. This technology makes initial ideas quickly tangible and offers great scope for creativity and flexibility.
Our products are now manufactured in a production facility in Saxony using a professional printing process.
Drawing
3D model
The bookhoover's journey begins with a hand-drawn sketch, which is then converted into a 3D sketch.
Written out as print data, they are sent to our production facility and printed there.
bionic design
Inspiration nature
State-of-the-art additive manufacturing techniques make it possible to reproduce the filigree structure of the Bookhoover. The bionic design of the finger holder is based on the wings of an insect.
A small number of bridge elements are integrated, which provide sufficient ventilation, are elastic enough for the finger and at the same time offer stability and support.
How does our 3D printing work?
Our raw material is PA12. The powdered polyamide is built up additively, i.e. layer by layer, using the multi-jet fusion process (MJF ). Only the material that is actually needed is used.
This allows us to save both material and energy during production. Our material, which is also used for prostheses, is dimensionally stable, durable, biocompatible and skin-friendly.
Additive manufacturing
Multi-jet fusion
Über einen Druckkopf wird eine wärmeleitende Flüssigkeit auf eine Schicht des Materialpulvers gespritzt. Mittels Infrarotlicht werden die Bereiche mit „Fusing Agent“-Auftrag stärker erhitzt als das Pulver ohne diese Flüssigkeit.
In this way, the areas for the component to be printed fuse together. In contrast to other 3D printing processes, this method eliminates the need for support structures - which would waste valuable materials as well as time and money.
cleaning
De-powdering
The components are removed and roughly cleaned.
In the second step, the surface of the belly parts is processed using glass bead blasting to remove any powder residue.
refinement
Steam smoothing
Anschließend erfolgt die Dampfglättung, um die Oberfläche zu versiegeln – die Bauteile sind somit wasser- und luftdicht. Langlebigkeit ist gewährleistet.
This process ensures that the initially grainy surface of the bookhover is smoothed while still retaining its unique "3D printed structure". This essential step also improves the mechanical properties and functionality of the component.
The final steps
We select the product colors very carefully before adding them to our range. The beautiful, matt look of our colors perfectly matches our designs and together they create a wonderful feel.
color
Diffusion bath
The dyeing process is carried out using DeepDye Coloring (DDC) technology. This is a "dye bath" with precisely controlled pressure and temperature.
This allows the color to penetrate deep into the printed, white bodies of the bookhover by means of diffusion. The dye molecules are distributed evenly throughout the material, resulting in an intense and uniform coloration.
Assembly
Handwork
Finally, the printed, colored individual parts are sent to the Bookhoover headquarters in Cologne.
Here we assemble all products by hand and provide them with the various pen units. We pack them lovingly and then send the Bookhover climate-neutrally via DHL GoGreen or Warenpost.
sustainable
Made in Germany
With innovative 3D printing technology, we can produce our minimalist design in a resource-saving way and exactly according to our ideas.
Our printing partner is a member of the Umwelt- und Klimaallianz Sachsen (UKA).
Manufacture
Zero Waste
To reduce material waste, we only print as many parts as are actually needed. With multi-jet fusion (MJF) technology, up to 80% of the material used is reused, which leads to a significant reduction in waste. Material residues that arise during production are fed directly back into the material cycle.
In 3D printing, only as much material is used as is actually needed. This minimizes waste. Complex geometries and customized products that would be difficult to realize with traditional manufacturing methods are suddenly possible.
The design speaks for itself: simple in form, appealing in aesthetics and functional in use.
