3D printer creates working wrench


3D printer creates working wrench

Scientists have created an amazing video showing how astronauts of the future will 'print out' their tools.
It shows work by the Z Corporation, in Burlington, Massachusetts, which specialises in 3D printers that can make almost anything - even tools with moving parts.
In the clip, made by National Geographic, a huge adjustable wrench is first of all scanned into a computer, down to the accuracy of 40 microns - less than the width of a human hair.
The image is then sent to a printer that uses a "specially engineered composite material" that starts out as a powder and is then bound together with a type of resin.
Within 90 minutes, it has created a fully working, robust copy of the original wrench that even features the adjustable head.

Theoretical physicist David Kaplan, from Johns Hopkins University, said: "So going into space, you just take a printer and you can print whatever you want."

German tools and German beer- a great combination.

I have just returned from the eisenwarenmesse , (if your German is like mine and is limited to ordering a beer, not to worry) its the Main Hardware and Tool show held in the German city of Koln (or Cologne).  Here all the main players in the market strutt their new products.  You also get to sample the various beers Koln is so well known for.  They are all on tap, and taste like nothing we have here.  I got stuck in this Brewery

I had been to the Koln Hardware show many years ago and immediately noticed the effect of the global economy with this visit.  There were a lot less exhibitors and visitors to the show. I thought it was because of them charging me the equivalent of R80 for a sandwich and tiny bottle of water, but alas I think the European crisis is having a bigger impact.
I managed to see most of the stalls and view their products, there is a lot of the same products being sold by different suppliers.  My focus has always been on alligning ourselves with quality conscious suppliers.  Price is one thing, but the real cost of poor quality is another. I think I have identified a few new products that would complement our range.  I will tell you more once they have been finalised. Just a teaser is ....
Rescue Tape Gets You Out of Nearly Any Bind (Without a Sticky Mess) -Duct tape is good for a great many things, but if you're sick of the sticky, messy hassle, Rescue Tape is a pretty great alternative. It sticks only to itself, and can patch holes, act as shrink-wrapping, or even mend wounds. Rescue Tape is kind of like a Fruit Roll Up, in the sense that it's stretchy, sticks only to itself, and can withstand a ton of heat, electricity, and pressure. You can use (Rescue tape not the fruit roll) it for just about anything, big or small—fixing pipe leaks, protecting boards while you're soldering, or even just as an impromptu bandage.  You can even seal things underwater or while a pipe is leaking. Best of all, it doesn't leave behind the awful residue that other tape does, despite its strength. The video  is pretty cheesy, but actually does a good job of explaining the hard-to-put-into-words product. (this product is a new product and we are still finalising our agreements, so no stock is available just yet)

We have just launched our version 1 (V.1) of our Apple app (Christensen Mobile App), it is available free to download from the App Store (Android and Blackberry to hopefully follow shortly)
App
The app is something that will evolve, and we will be adding new content.  One feature we quite like is the "send a photo"- If you are in a situation where you need a tool for a particular job but can't identify it, snap a picture and send it to us with the useful "send photo tool" on the App.  We also added a handy torch (lets hope there is no loadshedding).
There are some nice "How to Videos" in THIS section.
We have a new range of Padlocks designed to keep your stuff safe and locked up- there is an amazingly death defying video to go along with it!
The Fluke Fluke 2012 catalouge is Now Available.
Found a remarkable video where an Eagle owl is filmed at 1000 frames per second- truly beautiful.
Best regards ,
