About PJP 3D Printing

Polyjet 3D Printing is a 3D printing technology known for its customizable material properties and excellent surface finish. It works by jetting UV curable resin onto a build tray in a process that is somewhat similar to inkjet printing. PolyJet 3D printing offers one of the most advanced industrial 3D printing solutions available, producing parts with incredible precision and speed. It also supports the ability to print in multiple materials at once and can simulate rubber materials of different durometers, multi-color 3D printing, and simulated overmolds.

Overview

Fused Deposition Modeling (FDM), or Fused Filament Fabrication (FFF), is an additive manufacturing process that belongs to the material extrusion family. In FDM, an object is built by selectively depositing melted material in a pre-determined path layer-by-layer. The materials used are thermoplastic polymers and come in a filament form.

I. A spool of thermoplastic filament is first loaded into the printer. Once the nozzle has reached the desired temperature, the filament is fed to the extrusion head and in the nozzle where it melts.
II. The extrusion head is attached to a 3-axis system that allows it to move in the X, Y and Z directions. The melted material is extruded in thin strands and is deposited layer-by-layer in predetermined locations, where it cools and solidifies. Sometimes the cooling of the material is accelerated through the use of cooling fans attached on the extrusion head.
III. To fill an area, multiple passes are required (similar to coloring a rectangle with a marker). When a layer is finished, the build platform moves down (or in other machine setups, the extrusion head moves up) and a new layer is deposited. This process is repeated until the part is complete.

 

 

Support structure is essential for creating geomentries with overhangs in FDM because melted thermoplastic cannot be deposited on thin air. Surfaces printed on support will generally be of lower surface quality than the rest of the part. For this reason, it is recommended that the part is designed in such a way to minimize the need for support. 

Support is usually printed in the same material as the part. Support materials that dissolve in liquid also exist, but they are used mainly in high-end desktop or industrial FDM 3D printers. Printing on dissolvable supports improves significantly the surface quality of the part, but increases the overall cost of a print. 

FDM parts are usually not printed solid to reduce the print time and save material. Instead, the outer perimeter is traced using several passes, called the shell, and the interior is filled with an internal, low-density structure, called the infill. Infill and shell thickness affect greatly the strength of a part. For desktop FDM printers, the default setting is 25% infill density and 1 mm shell thickness, which is a good compromise between strength and speed for quick prints.

Frequently Asked Questions

Polyjet technology is used to make components and assemblies of different materials, colors, and transparencies in a single build.

In Polyjet printing, UV curable resin in ultra thin layers is jetted onto a build platform similar to inkjet printing, along with a gel like support material.

PolyJet works by jetting photopolymer materials in ultra-thin layers onto a build platform. Each photopolymer layer is cured by UV light immediately after it is jetted, producing fully cured models that can be handled and used immediately, without post-curing.

The minimum wall thickness required for PJP technology is 1mm.

The more accurate and detailed a product’s design is 3D printed, the more precise its final prototype will be.

SLA creates beautiful, detailed models, but is limited by breakaway support material, and overall mess created by the process. PolyJet technology takes resin-based 3D printing to a new level, with soluble support material, better print speed, and unmatched multi-material capabilities.
