Metal Jet printer from HP on display at AM conference

HP’s new metal printer for mass production builds parts from MIM powders, which lowers the cost per part

HP Inc. is showcasing its lines of 3D printing technologies at the AMUG (Additive Manufacturing Users Group) conference, running March 31-April 4 in Chicago. Among the attractions visitors to the company’s booth can see are the Multi Jet Fusion printer, for building thermoplastic parts, and the recently introduced Metal Jet system.

Metal Jet was introduced last September and, according to HP, is intended to meet the needs of customers seeking to mass-produce AM parts.

A whitepaper posted on the HP website says that Metal Jet relies on thermal inkjet technology to deliver a binding agent to a powder-metal bed containing standard metal injection molding (MIM) powders. The manufacturer claims that printing with these powders lowers production costs compared to systems that print with non-MIM powders.

The whitepaper cites the following benefits of Metal Jet:

• One large part or multiple small parts can be produced simultaneously in the 430- by 320- by 200-mm powder bed.

• Parts can be arranged freely in multiple levels in the bed to optimize packing density and productivity, thereby reducing cost per part.

• No build plate is required, unlike selective laser melting (SLM) technologies.

• Serial production of low-cost, high-quality parts.

• 1,200- by 1,200-dpi addressability in a powder layer that’s 50 to 100 microns thick.

• Finished parts having isotropic properties that meet or exceed ASTM and MPIF Standards.

Part 3D-printed on the HP Metal Jet system for mass production.

• Post-sintering density that exceeds 93 percent, which is similar to what MIM provides.

HP’s global head of metals, 3D printing, and digital manufacturing, Tim Weber, is scheduled to speak at the AMUG conference April 1 at 4:30 p.m. The title of his presentation is “Scaling into Mass Production with Metal 3D Printing–Technology Differentiation & Applications.” Also scheduled to speak at the conference is Weber’s colleague, Scott Schiller, HP’s global head of customer and market development. His presentation, “All About Our Customers–Removing the Hype and Making AM Real,” is scheduled for April 3 at 1:30 p.m.

My partner and I approached David at Re3dtech with our project and were greeted with kind and caring service. Throughout the last couple of months we have placed several orders in varying size and were even able to sit down with David and the owner to discuss our needs as a small business. Through this sit down we saw their passion for assisting both small and large clients in achieving their goals. We even had a hiccup with a batch of prints that was immediately addressed and remedied with precision and care. I almost don't want to recommend these guys because I feel like I have stumbled upon a hidden gem in 3D printing services and selfishly want to keep it to myself. Jokes aside we will be continuing our business relationship with the folks there and look forward to growing our order quantities and business with their help.
Re3DTech was instrumental in helping us get our product, Stroba™, to market faster! We needed a technology that could do snap fits and looks and feels as close the injection molded part as possible, and Re3D Tech was there for us. We used SOLIDWORKS Make to get in touch originally, upload models directly, and sign an NDA directly with their excellent team. It was really simple and easy to use their quoting tool as well. Excellent prices, excellent lead times, and superior quality are perfect words to describe our experience with Re3DTech. We went through many prototypes for Stroba™, and we at Goodfriend Innovations™ use Re3DTech for our other rapid prototyping jobs to help get our additional productions out to market faster than the competition. 5 Stars
I provided RE3DTECH three laser scanned ".stl" files for 3-D printing of prototypes. I used their on-line quote and file delivery process. The file acceptance and resultant quote were returned quickly. The parts were received at the quoted time. The parts are quite complex with many holes, angles, curvatures and notches. Each of the parts came out identical to the scanned parts dimensionally and passed the form/fit/function test in the upper level assembly. RE3DTECH has a high quality business process and produces high quality products. I will use them for future prototyping projects and recommend RE3DTECH.
Re3dtech is one of the most honest and reputable companies we have done business with. We decided to look into options for getting parts made in the USA for the retail market. It was awesome to find a local company with humble staff looking to provide their services meeting our criteria, not to mention meeting the Re3tech crew face to face and checking out their operation. Peter was very honest, knowledgable about design. Peter's creative element made working with him a great pleasure. Jim's flexibility was a breath of fresh air and greatly appreciated. CentralSound is proud to scratch the surface with Made in the USA parts in the retail market now, thanks to Re3dtech. Hope to do more business with them in the future.
Re3dtech has consistently delivered the best service I have ever received in the industry. Their response time is unmatched and they always stand by their parts and quality. They regularly make me look like an all star at my job.
It is always a pleasure to have a vendor that provides quality, experience, and always shows as much care for your order, and your product as you do!
