New Blood Recycling Machine Contains 3D Printed Parts

Behind the explosion in interest in additive manufacturing (AM) are a few simple facts that make the technology so appealing. Parts built through AM waste less material, are often quicker to produce, and can be much more complex than parts built using traditional manufacturing methods. These facts have led companies in every field, around the world to embrace 3D printing and experiment with new applications.

One of those new applications is a new blood recycling machine developed by Brightwake. Based in Nottinghamshire, UK, Brightwake is a “… creative development, engineering, production and research company specializing in the development of innovative solutions for all kinds of manufacturing, operational and logistical problems.” In this case, the creative development is called Hemosep and it was built in part using a Stratasys Dimension 1200es.

Lawrence Livermore National Laboratory Develops New Additive Manufacturing Process

Our electric grid would look very different if Nikola Tesla hadn’t looked at Thomas Edison’s plans for direct current and thought he could do better. In a similar vein, although it might seem like there is an additive manufacturing (AM) process for almost any type of production, there’s always room for fresh ideas. In this case, the new idea comes in the form of a different method for using an existing technology.

The Lawrence Livermore National Laboratory (LLNL) has developed a way to use electrophoretic deposition (EPD) for AM in a new process the lab is calling light-directed electrophoretic deposition. EPD itself has been used for almost 100 years as a way of coating materials through deposition. As an example, new cars can be primed using EPD by moving a positively charged car body into a negatively charged dunk tank. Continue reading

Rapid Ready Roundup: Stratasys, 3D Systems, Project Ara

In the course of my diligent efforts to keep you good people up to date on the state of additive manufacturing (AM), I come across many interesting news items. I’ll gather them up every so often and present them in a Rapid Ready Roundup (like this one). You can find the last Roundup here.

Today we’ll start with a couple pieces of news from Stratasys. First up, the company has released a new AM material called Endur. The new material is a simulated polypropylene for use with all Objet EdenV, Objet Connex, Objet500 Connex3 and Objet 30Pro AM systems. According to the company, Endur offers both high impact resistance and elongation at break, and has a heat-deflection temperature up to 129°F / 54°C (HDT @ 0.45MPa per ASTM D-648-06).

New 3D Printer Raises $2 Million on Kickstarter

Ask any three knowledgeable people what they think about home additive manufacturing (AM) systems and you’ll probably get three different responses. Some, like Terry Wohlers of Wohlers Associates, will tell you people don’t want or need a 3D printer in the home. Others, such as Joshua Pearce from Michigan Technological University (MTU), believe a home 3D printer is already useful enough to be given a place as a household appliance.

In the end, it’s consumers who will decide the issue, and some of them recently backed another home 3D printer, The Micro, on Kickstarter. The product of startup M3D, the Micro is being touted as the first AM system designed with home consumers in mind. Kickstarter backers can get one for a mere $299 (if they hurry), and early backers got an even better deal at $199. Continue reading

Titan 1 Desktop SLA 3D Printer from Startup Kudo3D

It wasn’t all that long ago that if you wanted a desktop additive manufacturing (AM) system, you were limited to material extrusion printers like those offered by Stratasys. Then came Formlabs and the first desktop stereolithography (SLA) printer, the FORM 1. It didn’t take long for other companies to follow Formlabs’ lead and now consumers have a choice of desktop SLA models to choose from, including a new model from 3D Systems.

Startup Kudo3D has spent the last couple years developing its own SLA printer, which it has named Titan 1. Rather aiming the digital light projector at the top of the resin tub, Titan 1 works with a bottom up model. Continue reading
