Potential of Full Colour Resins in WJP technology
One of the most attractive results you can achieve with 3D printing comes from using WJP (White Jet Process) technology and full-colour resin materials. This high-resolution technology can be applied in various industries, including the medical and educational fields, for artistic purposes, and also as props in movies, for creating realistic rapid prototypes and miniatures. It utilizes photopolymer jetting to create objects with a smooth surface, without the need for time-consuming post-processing. You can easily produce complex and precise 3D printed parts with WJP.
How Does WJP (White Jet Process) Technology Work?
These 3D Printers work in a very similar way to any inkjet printer. During the process, the printer jet layers of liquid photopolymer onto a build tray and then cures them with UV light.
After each thin layer of photosensitive resin is printed, it is irradiated with ultraviolet rays of a specific band to polymerise the full-colour resin just sprayed onto the building platform, achieving rapid curing. The nozzle continues working until the entire part is ready.
Benefits of WJP technology:
Accuracy:
With this innovative variable ink technology, you can achieve 3D printed parts with 600*600*1200 dpi printing accuracy.
Full colour objects:
Multicolour objects with ease; WJP technology combines digital imaging and material deposition to achieve full-colour, multi-material, voxel-level 3D printing.
Efficiency:
By utilising a full-width high-speed raster, wide-surface nozzle scanning injection molding method, we get a fast and efficient process of 3D Printing.

Application methods of WJP 3D printing technology
WJP technology's unique approach to 3D printing opens up new possibilities in additive manufacturing. You can create photorealistic parts with vibrant colours. At JLC3DP, we use an ABS-like resin throughout the process, which exhibits excellent mechanical properties, including high strength, high rigidity, and a certain level of heat resistance.
Medical industry
Multicolour 3D printing can be effectively applied in the medical industry. Doctors can now produce highly realistic, patient-specific anatomical models on demand.
To explain certain medical conditions, these 3D-printed organs and body parts help improve communication between doctors and patients by providing clear, tangible representations, enhancing patient understanding and engagement.
Alongside WJP 3D printing technology, other methods — such as SLA, or flexible materials like TPU used with FDM 3D printers — can also be applied to create practice models for surgeons. These samples support preoperative planning, reduce risks, and improve surgical efficiency.

Education
The application and benefits of 3D printing in the medical field are very diverse; it can also help medical students during their studies. A realistic, colourful 3D-printed organ supports the process of preparing for exams and, later on, working as a doctor. Of course, not only medical students can benefit from additive manufacturing. WJP 3D-printed parts can be used in any school to support teachers in presenting certain topics and lessons in the classroom.
Architecture
A miniature of a building or park, for example, can help architects present projects in the best possible way to their clients. Even if these models are just additional parts of the overall project, 3D printed elements can be a great help in showcasing their work. Architecture studios can utilize 3D printing in several ways.

Movie industry
As designing unique sets and sourcing the right items and materials can be time-consuming, the movie industry increasingly relies on 3D printing, especially full-colour parts for creating props. WJP technology offers a great solution in this field as well. Realistic full-colour objects help set designers work more efficiently, while other methods like FDM and SLA 3D printing can also be game-changers in the prop-making process.
Museums & Art
When thinking about museums and their collections, there is often a need to conserve delicate pieces and create realistic replicas. Additive manufacturing offers an ideal solution for preserving, especially sculptures.
In addition to conservation, colourful 3D printed models also play an important role in museum education. Every year, thousands of children visit museums to learn about history and culture. Additive manufacturing allows them to interact with accurate, touchable versions of certain artifacts, enhancing the educational experience.

What is Binder Jetting? Process, Benefits, and Applications
Binder jetting (BJ) is a versatile additive manufacturing technology that is used to print polymer, metal, ceramic and sand parts. The Binder jetting 3d printing technology uses powdered materials upon which the print head selectively deposits a liquid binding agent (binder) to fuse adjacent powdered particles together to form a bond. It can be understood better by considering it a mix of powder bed fusion and material jetting technologies in a way that it uses powdered material and also uses a binder......
What is Material Jetting 3D Printing | The Complete Guide
So, what exactly is material jetting additive manufacturing? It’s like those office inkjets, only this one’s built for serious work. Instead of laying down ink on paper, it shoots out tiny drops of liquid photopolymer onto a flat platform. A quick flash of UV light locks each pass in place. Layer after layer, the shape takes form until you’re holding a finished part. What makes it shine are the little things, sharp edges, clean surfaces, and the ability to blend materials in a single build. Material J......
Binder Jet 3D Printing: Complete Technology Guide
What is Binder Jetting 3D Printing? Understanding the Basics Binder jetting is often compared to inkjet printing, but on steroids. Instead of spraying ink on paper, the machine lays down a liquid binder onto a thin layer of powder. Each sweep of the print head sticks particles together, one layer at a time, until you’ve got what’s called a “green part.” Once it’s out of the machine, the loose powder is blown or brushed away, and the part usually needs curing and then sintering or infiltration to get i......
Binder Jetting vs Material Jetting Key Differences
Jetting Technology in Additive Manufacturing Jetting has become one of the buzziest approaches in additive manufacturing, but the word itself causes headaches. Binder Jetting technology, Material Jetting, Multi Jet Fusion (MJF), even Metal Jet, they all sound like they’re versions of the same idea. They’re not. Each one works differently and serves very different needs. The roots of jetting-based 3D printing trace back to plain old inkjet printers. Engineers noticed: if you can shoot microscopic drops......
How Material Jetting 3D Printing Tech Works & When to Use it
Material jetting is one of the most precise and visually detailed 3D printing methods available today. If you imagine how inkjet printers work, layering ink dot by dot, material jetting 3D printing works similarly, but with droplets of photopolymer resin or wax that are cured layer by layer using UV light. This method shines in applications where ultra-smooth surface finish, high accuracy, and color realism are critical. But it’s not for everyone, costs, material options, and durability limitations ke......
