Polymaker will offer the Polymaker PC-r 3D printing filament made from recycled polycarbonate (PC). The PC for the filaments comes from materials supplier Covestro and consists of a combination of recycled plastic waste and virgin material.

The combination of recyclates and virgin material reduces the<sub> </sub>carbon footprint of the polycarbonate and still allows it to be extruded into filaments

Currently, small wind turbines can hardly be operated profitably in landlocked regions. This drawback has now been overcome by the partners EAB Gebäudetechnik Luckau GmbH and the Chair of Polymer-based Lightweight Design at the BTU Cottbus-Senftenberg: passive smartblades made from 3D-printed molds adapt independently to wind conditions. This is achieved by an intelligent layer structure and its bending-torsion-coupling.

This newly developed rotor blade is especially suited for weak-wind regions and adapts independently to the wind load

PA66 and PBT considerably expand the field of applications for laser sintering by showing better properties than classic PA11 and PA12 materials in most cases.

As a temperature-resistant and flame-retardant material with high mechanical properties, PA66 opens up new application possibilities for laser sintering, such as its use as a sensor holder

Production is becoming ever more flexible, diversified and decentralized. Without doubt, additive manufacturing processes make a crucial contribution to this, also initiating the transformation from production-based design to design-driven production. In this article, the 3D printing service provider FIT outlines a best-practice panorama of current technologies.

One-Stop Realism Drives near Instantaneous Decision-Making 

Stratasys Ltd. offers world’s only 3D printer to produce full color, multi-material prototypes and parts in a single 3D print, eliminating time-consuming processes and accelerating product concepting, design, decisions, and delivery. The J750 enables customers for the first time to mix-and-match full color gradients alongside an unprecedented range of materials to achieve one-stop realism without post-processing. 

The Stratasys J750, the premier addition to the Objet Connex multi-color, multi-material series of 3D Printers, allows customers to choose from more than 360,000 different color shades plus multiple material properties - ranging from rigid to flexible and opaque to transparent. Prototypes can include a vast array of colors, materials and material properties in the same part, speeding production of realistic models, prototypes and parts for virtually any application need - as well as delivering incomparable 3D printing versatility to produce tooling, molds, jigs and fixtures and more. 

The J750 enables near instantaneous decision-making by streamlining the way products are designed, evaluated and brought to market. A true industry milestone, the productivity-boosting J750 is expected to improve TCO (Total Cost of Ownership) by eliminating many of the traditional complex processes, time and resources required to create product-matching prototypes. Designers and engineers can physically experience true product prototypes within hours of developing an initial concept for immediate design and function validation with internal stakeholders and end users. Design decisions can be made instantaneously and with full confidence to help accelerate product delivery. 

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

The Stratasys J750 also minimizes downtime associated with material changeovers. Featuring a large, six-material capacity, it keeps the most used resins loaded and ready for printing. Newly designed, state-of-the-art print heads means simulated production plastics, like Digital ABS, can be 3D printed in half the time of other Stratasys PolyJet systems. As 3D printed models are delivered complete with full colors, color textures and multiple materials, no time is wasted on painting and assembly. 

“With its one-stop realism, the J750 is quite simply a game changer. By combining full color with multiple materials and a streamlined workflow, it recalibrates the impact of 3D printing in the product development cycle," said <b>Josh Claman </b>, Chief Business Officer, Stratasys. "Informed design decisions can be made immediately after the concepting stage. The time saved by eliminating the painting and assembly process can lead to faster product delivery times. The J750 is a multi-purpose system that can also produce production tools, manufacturing moulds, teaching aids, and other models – truly raising the bar in 3D printing versatility.”
