Stratasys’ New Multi-Material J750 3D Printer Sets the Bar for Most Realistic 3D-Printed Objects

stratasys 3d-printed shoe

This sports-shoe prototype was produced with full color, smooth surfaces, and a rubber-like sole – and all in a single print operation with the Stratasys J750 3D Printer.

One of the major limitations of conventional 3D printers is that typically they can only produce objects made of one material – usually a brittle, plastic substance, and in color. However, since 2014, one of the market leaders in the 3D-printer industry, Stratasys, has been introducing multi-color, multi-material 3D printers. It recently introduced its most advanced multi-color, multi-material 3D printer, the J750. According to the firm, the J750 enables users to mix-and-match full-color gradients along with a range of materials to achieve “one-stop realism without post-processing,” making it the choice for product designers, engineers, manufacturers, and service bureaus.

The J750, which print layers as thin as 14 micros – or as fine as the dust from confectioner’s sugar – is Stratasys’ “premier addition” to its Objet Connex multi-color, multi-material series of 3D printers. With the J750, customers can choose from more than 360,000 different color shades, as well as choose from multiple material properties that range from rigid to flexible, and opaque to transparent – so that they can produce prototypes such as the sports shoe shown above that combine one material type for the body of the shoe, and rubber material for the sole of the shoe. Up to six different materials can be loaded and used at one time.

Because users can create prototypes incorporating an expanded range of colors, materials, and material properties in the same part, production of realistic prototypes and parts can be done much faster. According to Stratasys, this will ultimately improve TCO (Total Cost of Ownership),  eliminating many of the traditional complex processes, time, and resources required to create product-matching prototypes, as there’s no need to paint and assemble objects.

Increased Productivity and Throughput with New PolyJet Studio and Six-Material Capacity

The J750 is supported with a streamlined workflow beginning with the all new PolyJet Studio. The software’s new user interface allows users to choose materials, optimize the build, and manage print queues, and assignment of colors, transparencies, and rigidity is made easy via familiar design controls. Color textures can be loaded fully intact via VRML files imported from CAD tools.

The firm says newly designed, state-of-the-art print heads means simulated production plastics, such as Digital ABS, can be 3D-printed in half the time of other Stratasys PolyJet systems.
