GrabCAD is at 3D Printshow London 2013

3D Printshow has become one of London’s most talked-about shows. Blending technology, art, design and medical applications with a live show that features music and fashion, it gives visitors a glimpse of the future, where 3D printing will be used across almost every industry. GrabCAD is happy to be part of this year’s event which is live NOW!

Business Design Center London

Last month 3D Printshow London launched a GrabCAD community challenge calling for unique and functional household item designs that could be printed in 3D. After a month of incredible submissions, GrabCAD VP, Rob Stevens, announced the winner live at the event today.

Engineer’s Spotlight: Anirban Ghosh wins “Eyes to Hear With” Challenge

GrabCAD recently finished the pro bono Challenge to design an easy to manufacture closed caption pair of glasses for the hearing impaired. The community submitted a lot of great entries, but as always, there can only be one 1st place.

Challenge Results: Velodroom gets sleek new bike accessories from GrabCAD community

Velodroom is a bicycle accessory brand with a unique take on the world and cycling, offering products that are designed to increase the quality and safety of daily riding.

Making new and innovative products for bicycles, which have been around for 100 of years, isn’t easy. So Velodroom came to GrabCAD’s world-leading platform for hosting engineering and design competitions, and challenged the community of now over 700,000 engineers to create an accessory that solves a problem cyclists face daily, all while keeping Velodroom’s style in mind.

The GrabCAD community didn’t disappoint. There were 152 entries submitted and some truly well thought out designs for the biking community.

Here are the top three winners:

MWL – Electric CAD

The recent Challenge with NOKIA reminded me of the great models we have that focus on all things electric. Whether it’s circuits, motors, connectors, switches, or other accessories – GrabCAD has plenty of electric CAD to keep you busy this weekend. Get inspired, start a new project, or find something cool to set your scene!

Molds We Love

Sometimes when one is under pressure to get their injection mold tooling done, turning to GrabCAD for a little help is a great idea. When you need 60,000 of something, the mold has to be right, or else you have 60,000 mistakes. There are lots of different designs in our library – many of them made by professionals in real-world applications. Lots of lessons to learn from there. Here are some of our favourites.

Here is a flow simulation by GrabCAD Legend Stefan Varga. Everything was created in Moldex3D and comes complete with a shrinkage analysis.

Models We Love – Rhino

Rhinoceros 3D, known as Rhino is quite an interesting CAD tool. Widely favoured by Product Designers, Architects and Automotive Designers because of its ‘free-form non-uniform rational B-spline (NURBS) modeling’, allowing the creation of curvilinear designs easy as pie. There are also hundreds of third-party plugins. At the beginning Rhino was distributed freely, allowing a community to spring up to help de-bug and improve newer versions. Sounds familiar, no?

Models We Love – Circles

It’s π Day. The Internationally recognized day of remembrance for our irrational yet mathematically constant friend, 3.14159… So this time we looked for the models that reflected the best usage of π in CAD. That would nearly everywhere, sometimes hidden in plain view. Can you think of a moment when you aren’t using π in some small way for a large, obtuse but very difficult Engineering proof?

Sudhir Gill created this Angle Calculator for a Design challenge we had last year. What an amazing idea. By combining the elements of a slide ruler and a protractor, Sudhir came up with an elegant way to calculate angles quickly. Sometimes you only need a little bit of π to do useful work.
