As part of the larger Research for Additive Manufacturing in Pennsylvania (RAMP) program, 3D Systems has announced a new award scheme for universities researching future 3D printing technologies.

Along with Commonwealth of Pennsylvania and America Makes, it announced that grants of $1m have been awarded to Carnegie Mellon University and Lehigh University, while additional private industry in-kind contributions to a value of $1m are being provided to fund both projects.

Ultimately the project is a drive by Pennsylvania to spark interest from some of the State’s best universities in collaborating with its manufacturing and technical institutions, a smart move for a state edging to be at the forefront of America’s movement to re-shore manufacturing.

Autodesk Labs has announced Project Ventus, a surface wrapping tool for CFD simulation

Q3, that ever so sexy way of saying ‘summer is almost over’, is upon us, which more positively gives us some new software from Autodesk Labs to get excited about.

Autodesk Labs has announced Project Ventus for Simulation CFD, a surface wrapping tool to take a model, surface wrap it, add an external volume, and generate a CFD quality mesh that can be imported to Simulation CFD.

According to Labs program manager Scott Sheppard: “The intent is to easily generate a mesh for CAD models that might otherwise be difficult or impossible to mesh for CFD simulations without extensive CAD cleanup.”

Theorem’s Multi-CAD plug-in allows PTC Creo data to work interactively within Catia

Theorem Solutions has launched Multi-CAD, a new ‘smart PLM’ tool benefitting those working with PLM and design data collaborations between Catia and PTC Creo.

Developed specifically for Catia V5 and V6 and PTC Creo, the plugin transforms collaboration by enabling the Dassault Systèmes software user to work interactively with Creo parametric data directly from within a Catia design environment.

Able to process tessellated and precise data plus product manufacturing information, Theorem’s Multi-CAD solution can be run from within the V5 or V6 interface or configured to batch process multiple files for improved efficiency.

Sand casting parts using 3D Printing brings digital detail to traditional process

Anthony Middleton of Grainger and Worrall shows explains the intricacies of 3D core printing

Far from the traditional image of a castings manufacturer, Grainger & Worrall (G&W) is working with some high end digital tools to provide bespoke prototyping solutions using rapid-tooled and tool-less digital processes.

One of the only independent UK casting business to employ in-house ExOne 3D sand printing and CT scanning technology as part of its rapid prototyping process, G&W is using these technologies to enable projects like fully-machined engine cylinder head development in less than six weeks.

Sand castings have been used in lots of different industries, the bronze age and the iron age, for example, wouldn’t have got far without them, but the modern version relies on complex metallurgical and chemical interactions, thermo and fluid dynamics.

Despite calling itself a ‘value proposition’ DST SimWise 9.5 crams a lot into one package

Billing itself as the ‘affordable and flexible physics based simulation software for the professional and education markets’, DST has announced the availability of SimWise v9.5.

The release expands the FEA, CAD integration, and interoperability capabilities of the product, while optimisation tools have been improved to allow DSTDimension and other parameters from select CAD systems to be transferred to SimWise and used as optimisation variables.

The release introduces a new 3D FEA mesh generator from which users are told they can expect quicker results from FEA, Motion plus FEA simulations and optimisations that include FEA results.

Making stuff: rotational moulding

A simple desktop rotomoulder like this is the baby of the bunch

Recently we paid a visit to London-based design consultancy PDD, and although we left having learned about its work on lots of various projects, one thing stuck in our mind - a mini rotational moulding machine.

‘Rotomoulding’ is a way of turning a liquid resin around inside the mould so that it eventually sets as a solid having thinly coated the form of the mould (but you already knew that), spinning and tumbling around, with occasional jerks and pauses to get the most consistent finish.

Despite being in the costly confines of West London, PDD still has space for a well equipped workshop, in which PDD’s principal for design development Mark Hester showed me the mini rotomoulding rig he’d built for moulding plastic bottles.

3D depth scanner made by modding your smart phone

Transforming a standard digital camera so it can perceive 3D depth of field

Research from Microsoft suggests that with a few modifications an ordinary digital camera, like the one on your smartphone, can be used as a 3D depth camera.

While efforts like Google’s Project Tango are planning on adding depth cameras into our mobile gadgets of the near future, Microsoft has been looking to make access to developing 3-D applications easier by lowering costs and technical barriers to entry for such devices.

As featured in the MIT Technology Review, a group of researchers modified web cameras by removing the near infrared filter (used in cameras to block unwanted light signals in pictures) before adding a filter that only allowed infrared light to pass, surrounding the lens with a ring of several cheap near-infrared LEDs.
