HP Jet Fusion:
CB PA 12 (full-color)
The Multi Jet Fusion technology not only offers industrial solutions, but also the potential to create full color objects. The polymer is also polyamide 12. However, the 3D printer and printing process differ from standard Multi Jet Fusion .
The full color version offers unlimited design variety and a faster turnaround time. However, for technical reasons, the printed objects are minimally less mechanically resilient and somewhat more expensive to produce.

Colored prototypes
RAL colors specific to prototypes are often helpful to get as close as possible to the final component. All common RAL tones can be realized with CB PA 12 and the components can be manufactured in as little as 48 hours. Compared to the standard coated PA 12, this solution is much faster to realize.
Jigs with color coding
Color information can be used to speed up the production process or to reduce error rates. In addition to simple directional symbols, images of the component can also be applied, or different elements can be designed in different colors (for example, when assembling several workpieces).
End-use parts with color elements
Color elements on components, such as casing components or structural workpieces can fulfill different functions. In addition to elements such as logos or labels, they can also be functional in nature, for example, with instructions on operating elements, directional information or color-separated, functional elements.
Scientific & educational models
Biological, medical, geographic and historic objects can be fabricated using the HP Multi Jet Fusion 3D color printing process. Extremely complex models, such as molecular and organ models, can also be printed in full color.
Minimum order value:
- Minimum order value: EUR 50,- + 19% VAT (EUR 59,50 incl. 19% VAT) / order
- Minimum order value per part:
- EUR 25,- + 19% VAT (29,75 incl. 19% VAT ) for rush production (48 h)
- EUR 10,- + 19% VAT (11,90 incl. 19% VAT) for 7 days standard production
- What means minimum order value per part? If the quantity multiplied with the price per piece is lower than the minimum order value per part, the minim order value applies. For example
- Minimum order value per part EUR 10,- (standard production)
- Price per part: EUR 8,-
- Price 1 piece: EUR 10,- (minmum order value per part applies)
- Price 2 pieces: EUR 16,- (minimum order value per part does not apply)
Discounts
- We offer discounts for higher quantities and sets. Availability and volume of discounts depends on quantity and part geometry. Please submit a manual request for discounts.
Approximate values
- Prices are calculated based on total size of the object and material consumption
- Typical prices per cm³ are EUR 1.20 – 2.00 + 19% VAT (depending on part geometry and quantity)
Look & Feel
- The surface is slightly rough.
- CB PA12 is light (density ~1.01 g/cm³).
- As in all 3D printing technologies, printing layers (80 microns layer height) may be visible.
Characteristics
- Thin structures can be brittle; thick structures are strong.
- Resistant material: chemically resistant, mechanically strong and heat-resistant up to ~100°C.
- One of the most durable 3D printed materials.

Minimum Wall Thickness
The minimum wall thickness should be no less than 0.6 mm. For long structures or structures which must endure mechanical stress, the wall thickness should be increased.
Cavities
Hollow parts can be printed, as long as they contain escape holes with a diameter of 5 mm or more, which allow the removal of excess material. For larger cavities two or more escape holes are left.
The material is compacted during the printing process and therefore challenging to remove. Hence, thin tubes integral to the part might end up containing excess material which cannot be removed.
Clearance Gap
In case your file contains several shells, make sure to keep a clearance gap of min. 0.5 mm between the shells, otherwise they could be fused together.
Resolution
The minimal details size should be no smaller than 0,3 mm.
Interlocking parts
Interlocking parts can be printed; a distance of min. 0.5 mm must be allowed between the objects. Make sure that this area can be accessed in order to remove excess powder.
Bounding box
The maximum size of the part cannot exceed 332 x 190 x 248 mm.
Standard-Finishing
- Cleaning parts from excess material
- Bead blasting
Optional Finishing
- Manual polishing

A thin layer (80 microns) of powder is spread on a retractable build platform. A print head ejects tiny drops of ‘fusing agent’, a heat-conductive liquid, onto selected areas. The powder is then exposed to a heat lamp. The areas covered with the fusing agent absorb energy from the heat lamp and reach a temperature at which the powder melts. Once the heat source is removed, the (now liquid) powder cools down and solidifies.
A second agent, the detailing agent, is ejected simultaneously with the fusing agent and covers the areas which are not required for the model. The detailing agent is an isolating liquid. It ensures that the powder around the model does not absorb sufficient energy to melt.
The process repeats until all layers are solidified. After printing, the entire build chamber is left to cool down for several hours. Once the target temperature is reached, the parts are removed and cleaned from excess powder.
