By | 2017-12-21T08:35:44+00:00 October 27th, 2017|Categories: 3D Printing / Additive Mfg, HP Multi Jet Fusion Technology|0 Comments

HP brings decades of experience in 2D printing and materials science to the 3D printing market. With the development and release of this platform, they seek to address the demands for increased speed, throughput, and productivity in additive manufacturing. The HP Jet Fusion 4200 is made up of the printer, build unit, and processing station. To begin, HP material cartridges are first inserted into the processing station. The station performs an automated mixing process, and the materials are loaded into the 3D Build Unit. The build unit is now ready to be placed into the printer. In the printing stage, a layer of material powder is first spread across the build area. In one continuous pass, fusing and detailing agents are applied, along with energy to further fuse the layers. The build area then moves down a layer and the loop is repeated until the parts are complete. Upon completion of this stage, the build unit is removed and placed in the processing station to cool. A second build unit can then be inserted back into the printer for the next build. The HP Multi Jet Fusion has a closed loop thermal control system, which measures hundreds of points on [...]

Re-engineering Engineering with ANSYS

By | 2017-09-27T08:22:10+00:00 September 27th, 2017|Categories: 3D Printing / Additive Mfg|0 Comments

Additive manufacturing is the poster child of the engineering world right now. There are other posts on the web and on the ANSYS blog talking about this and what the opportunities are that it brings. But we need to talk about the changes that must be made to the whole product development process. It’s pretty well understood that product development is pretty well down the path to shift away from a time when simulation was used to figure out why something broke. Simulation is more routinely being used up front in the design process to develop products that are, more often, right the first time. Simulation Driven Product Development process We call this Simulation Driven Product Development. It’s a great strategy and means that the engineering simulation and design are brought closer together. You can try different loadings and designs to make sure that by the time you do go to test, you’re very confident in your design. Building and testing are very expensive and time-consuming so any improvements in this process generally mean big savings. With additive manufacturing, the whole engineering process gets a few more steps which actually add a lot more complexity. I won’t cover [...]

Metal 3D Printing for Manufacturing

By | 2017-12-21T09:16:21+00:00 September 8th, 2017|Categories: 3D Printing / Additive Mfg, Desktop Metal|0 Comments

Reprint from www.techcrunch.com Desktop Metal has already earned a number of fans with its 3D printed metal technology — Lowe’s, Caterpillar and BMW were all among its earliest clients. As first noted by CNBC, the Massachusetts-based startup is also getting some healthy monetary support, adding $115 million of venture funds to its coffers this week. The Series D features a number of high profile names, including New Enterprise Associates, GV (formerly Google Ventures), GE Ventures, Future Fund and Techtronic Industries, the holdings company that owns Hoover U.S. and Dirt Devil. Founded in 2013 by four MIT professors, Desktop Metal isn’t the first company to bring metal 3D printing to market, but it’s probably the most efficient. By its own measure, the company’s machines are able to print objects at up to 100-times the speed of their competitors. That’s good news for those clients using Studio, the prototyping machine the company announced last year — but even more useful for those planning to use the upcoming Production, a system designed to bring the technology to manufacturing. Speed has been of the main bottlenecks in mainstreaming 3D printing for manufacturing — metal or otherwise. The Production system isn’t going to replace wide [...]

New Metal 3D Printing Process

By | 2017-12-22T08:22:38+00:00 August 23rd, 2017|Categories: 3D Printing / Additive Mfg|0 Comments

Bound Metal Deposition Uses MIM to Create New Metal 3D Printing Process by Dave Macfie and Shawn Spinneweber, Cimquest The advent of metal 3D printing, also known as additive manufacturing, has promised to dramatically change the way products are made. The benefits are: the reduction or elimination of up-front tooling and increased complexity due to the removal of conventional manufacturing constraints which lead to shorter lead times, part consolidation, and weight reduction. Today, metals represent one of the fastest growing segments in 3D printing globally. Shipments of metal 3D printers increased by 51% in 2015, compared to 2014, and they continued to climb in 2016. Various research firms project additive manufacturing will be a $20B industry by 2020. (Source: Wohler’s Report 2016). While global metal manufacturing is estimated to be a $1 trillion industry. In spite of this growth, metal 3D printing options have not been accessible for the majority of manufacturers due to their cost and operational complexity. In addition, most technologies have relied on slow, laser-based processes that demand high levels of manual labor such as removal of metal supports with CNC. Handling the metal powder also poses health and safety issues which require a larger investment in [...]

3D Printing for Low Volume Production

By | 2017-12-22T08:24:17+00:00 August 18th, 2017|Categories: 3D Printing / Additive Mfg|0 Comments

Companies in certain industries sometimes require customized end-use parts, used to either replace older parts or improve upon infrastructure. While necessary, the cost and time barriers associated with one-off parts can cause for engineering teams to postpone or even eliminate projects altogether. Siemans Mobility based in Germany develops technology for vehicles and infrastructure for transport machines. The unique needs of their customer base demands innovation in low run manufacturing. One of their customers, The SWU Verkehr, provides transport services across 10 trains in the city of Ulm. The SWU decided to rework an existing armrest for the driver seat of a city train. This modification included the addition of three extra buttons for the control system, a design requested by many of their train operators. While something like this seems fairly straightforward, the part is traditionally made from glass fibre plastics with injection molding, welding, and milling. Through these methods, Siemens would be limited to only taking orders above 10 parts, because anything lower would be cost prohibitive. Excess parts would be stored until they were used or became too outdated to use. With this growing demand for one-off parts, Siemens saw the opportunity to innovate with 3D printing. This [...]

FDM Thermoform Tooling: What It Is and Why It Works

By | 2017-12-22T08:24:49+00:00 August 16th, 2017|Categories: 3D Printing / Additive Mfg|0 Comments

A kitting tray 3D printed using thermoformed plastics. There’s a good chance you interact with multiple thermoformed products on a daily basis, whether that be in your grocery store, your car, or probably even your fridge. But what does it mean if something is thermoformed? Thermoforming is a conventional plastics forming process where heat is used to bring a sheet of plastic to its sagging point, or when it becomes pliable. The heat source is removed and the plastic sheet is positioned onto a mold. A vacuum is then drawn through the mold and the sheet conforms to the surface of that mold. Thermoformed products are prevalent throughout manufacturing industries; including medical, outdoor/recreational equipment, automotive and aerospace. Typical products most commonly seen are trays, various housing components, wind deflectors, tubs, and most frequently — packaging. Using conventional methods, creating the tools for thermoforming can be a long, grueling process. Often these tools, especially if outsourced can take anywhere from 6-14 weeks depending on tool complexity and CNC capacity. This timeline is unattractive when you only need tooling for a short production run or a prototype tool. Typically, short-run, prototype and bridge tooling are made of a lower-cost tooling [...]

Additive Manufacturing Changes How We Think About Design

By | 2017-12-22T08:25:48+00:00 August 9th, 2017|Categories: 3D Printing / Additive Mfg, Stratasys|0 Comments

As 3D printing has become more and more mainstream, the traditional resource and skills barriers for manufacturing are all but vanishing. This trend is changing the very face of design. For the first time, producing complex products is no more difficult, expensive, or time-consuming than making simpler objects. 3D printing a block with holes, notches, and rounded edges is as approachable as printing a solid block once was. The 3D printers give designers unprecedented control over the shape and composition of matter. High-end 3D printers can combine multiple materials into arbitrary patterns at a high resolution, leading to the ability to create geometry with fidelity and complexity never before seen. Traditionally, making more complex objects required a heavy investment in time, equipment, energy, and labor. Now, the cost of adding an additional design feature is reduced, potentially triggering nothing short of a manufacturing revolution similar to the first industrial revolution triggered when the cost of power was similarly diminished. And as 3D printing evolves, these products can be produced quickly and produced in bulk. The Factory of the Future is Here Now Manufacturers are finding applications for additive manufacturing that go beyond experimentation—and that instead are relevant, practical, and profitable. [...]
