3D Printing in MJF Technology
Speed, precision, and reliability in contract manufacturing.
HP Multi Jet Fusion (MJF) technology is the foundation of industrial 3D production at COSMOLD.
It combines the repeatability and quality characteristic of injection molding with the flexibility of additive printing – an ideal solution for short runs, prototypes, and finished functional components.

HP Jet Fusion 5620 Pro
Industrial-class printer of the new generation.
The HP Jet Fusion 5620 Pro printer is a production-class device designed with scalability, repeatability, and full process control in mind.
The system based on HP Digital Production Suite integrates printing, analytics, and production cycle management, creating a complete solution for industry.
How does MJF technology work?
The MJF process involves precise application of polyamide powder layers, which are activated by two types of agents - fusing and detailing
and then fused with heat.
This allows achieving homogeneous parts without supports, with smooth surfaces and high dimensional stability.

Step 01
Professional post-production
At COSMOLD, post-production is not an addition but a key stage of the process. Thanks to automated DyeMansion systems, we provide perfectly clean, smooth, and colored parts — ready for assembly, sale, or direct use in production.
Step 02
DyeMansion Powershot X
Versatile cleaning and surfacing system for MJF prints — modes “PolyShot Cleaning”, “Surfacing”, or both combined. Cycle speed 5-40 min, basket volume ~26 l, designed for serial production with excellent surface finishing.
Step 03
DyeMansion Powerfuse S
Advanced “VaporFuse Surfacing” system for smoothing MJF and TPU parts — achieves an appearance almost like injection molding. Chamber volume: 85 l, cycle: 45-180 min, compatible with automation and Industry 4.0.
Step 04
DyeMansion DM60
Comprehensive 3D printed part coloring system — unlimited color palette, ISO-certified formulas, cycle approx. 150 min. Supports A MJF, PA12/PA11, TPU and preserves color depth and process repeatability.
Perfect 3D finishing
From raw print to premium-class product.
Thanks to DyeMansion systems, each part undergoes full post-production – cleaning, smoothing, and coloring. We achieve a surface quality comparable to injection molding.
Precisely controlled processing stages ensure color repeatability, smoothness, and durability. These give our prints their final look, functionality, and professional character ready for use.

Polyshot
Automatic cleaning and surface preparation after MJF printing.
The PolyShot system precisely removes powder residues from hard-to-reach places, providing an even, matte finish without damaging the detail.
This is the first stage of post-production that not only improves aesthetics but also prepares parts for further processing – smoothing or coloring. Ideal for mechanical parts, housings, and assembly components.
Vaporfaze
Advanced surface smoothing by vapor smoothing method, implemented in Powerfuse S system.
In this process, parts are exposed to special solvent vapor, which evenly softens and seals their outer layer. Thanks to this, they achieve appearance and properties similar to injection-molded elements — smooth surface, higher chemical and mechanical resistance, and reduced water absorption.
This solution is chosen for aesthetic components and parts that must meet sealing and easy cleaning requirements.

DeepDye Coloring
Industrial coloring and tinting of elements in a wide palette of colors.
The DM60 system uses DeepDye Coloring technology, where the dye penetrates deeply into the material structure, creating durable and saturated colors resistant to abrasion and UV radiation.
Thanks to the controlled thermal process, full color repeatability in large production series is possible. This solution gives parts not only aesthetics but also an additional protective layer against moisture and dirt.
Types of surface finishes
MJF 3D printing at COSMOLD is a solution for companies that value flexibility, short lead times, and high quality. We support both startups and large industrial plants.

Uncleaned sample
Raw surface, without removal of powder after printing. Rough, porous, and matte — excellent for comparing finishing effects in subsequent post-production stages.
.jpg&w=3840&q=100)
Cleaned sample
Basic removal of powder residues. Retains the natural color of the material and a slightly rough texture. It is the starting point for further finishing stages.

PolyShot Surfacing
Mechanical surface smoothing in the Powershot X system. Gives an even, satin matte and improves parts aesthetics, without affecting dimensions or tolerance.
.jpg&w=3840&q=100)
PolyShot + DeepDye
Combination of cleaning and coloring in DM60 technology. Parts gain intense, deep color and smooth, aesthetic surface with high durability.
.jpg&w=3840&q=100)
VaporFuse Surfacing
Advanced chemical smoothing in the Powerfuse S system. The resulting surface is sealed, shiny and resembles injection molding, providing protection against moisture and dirt.
.jpg&w=3840&q=100)
VaporFuse + DeepDye
Smoothing and coloring in one process. Elements achieve the highest level of aesthetics and resistance – smooth, color-saturated, and ready for direct final use.
