MINI World Rally Championship Team Sees 3D Printing as Critical Tool

Posted: 12 May 2011 01:00 PM PDT

For race car team, the process costs as little as one-fifth the amount of traditional methods

FRANKFURT – 12th May 2011 — (NASDAQ: SSYS) Stratasys today announced that its Dimension 3D printers and Fortus Production 3D Printers played a critical role in the development of the new MINI John Cooper Works World Rally Car (WRC).

The MINI Cooper WRC Team used the additive manufacturing machines to create a full-scale mock-up of the vehicle directly from the CAD (computer aided design) files, and it used the technology extensively on other assemblies and components of the vehicle.

The MINI WRC Team relied heavily on 3D printing throughout the car's two-year development cycle. To design the test car, engineers used Stratasys FDM 3D Printing technology to create large parts of the engine bay, gearbox, steering assembly, vehicle interior and even engine components, such as intake valves. In addition to prototyping parts for the test track, the MINI WRC Team even produced some end-use parts for the finished car. One of the most visible of these is the ergonomically styled gearshift display and control panel, which is mounted on the steering column.

The development of the car, which will be featured in this year's World Rally Championship, has impressed upon MINI WRC Team the importance of 3D printing in saving time, reducing tooling costs and enabling more design freedom of complex geometric parts.

"We would find it nearly impossible to build another car without using FDM technology," said Paul Doe, chief design engineer. "We would never have dreamt of building the parts we did without the Stratasys machines. Using composite parts would have cost up to three to five times more."

"MINI WRC Team's use of FDM technology to develop a race-worthy car for WRC demonstrates that it's both efficient and cost effective," said Tim Heller, managing director of Stratasys Europe. "It's nice to be considered an indispensable part of the prestigious team's operation."

MINI WRC Team used Stratasys Dimension 1200es 3D Printers and Fortus 400mc Production 3D Printers with polycarbonate and ABS materials.

Hi ,

Please can some body pinpoint exact difference between Statement Level Trigger and Row level trigger , please explain using some very simple example in both cases ?

1) How does UPDATE,INSERT Operation work in both of these type of triggers(Please
give some example).

2) What is exactly AFTER INSERT ON Table_name , does it mean after inserting some values
in trigger we fire this trigger ?

Please while explaining row level and statement level trigger give a simple example ,

thanks !!

Haryana engineering students invent oxygen-run bike

Posted: 12 May 2011 12:15 PM PDT

In a bid to promote green energy, some engineering students of Palwal city in Haryana have designed a motorbike that can run on oxygen.The idea originated with the need of alternate fuel, which can reduce the dependency on non-renewable fuels such as petrol and diesel."This bike is set apart from the others because its engine suffers no blast, nor does the temperature rise. The air is compressed and sent to the engine. The piston reciprocates to the air pressure leading to an up-down movement, making the flywheel run, and therefore, making the bike start," said Pratham Pal, one of the inventors.Devised as part of a college project, the bike can travel for about 500-600 kilometres at 100 litres at 300 PSI (pound-per-square-inch) of oxygen at the speed of 10-20 kilometres per hour.

How to pass command to command prompt without opening the prompt window ?

Posted: 12 May 2011 07:59 AM PDT

Hello friend's
As we know by passing the command through batch file we can able to execute our java application just by double clicking the batch file.But our cmd prompt is opened in that case.
So i just want to pass the command to command prompt without opening the cmd prompt window.So how to make such like a batch file ?

Is there any function in c or c++ by which we can able to pass our command to command prompt ?

Angry birds web version was launched recently and the JavaScript experts have launched a quick hack to unlock all Angry Bird levels.

To unlock all levels in Angry Birds Web use:

Code:

javascript: var i = 0; while (i<=69) { localStorage.setItem('level_star_'+i,'3′); i++; } window.location.reload();

To revert use:

Code:

javascript: var i = 1; while (i<=69) { localStorage.setItem('level_star_'+i,'-1′); i++; } window.location.reload();
