What is 3D Printing ?

without comments

Many processes can these days be modelled or reproduced by computer. One of the most exciting of all is 3D Printing. The term ‘3D Printing’ is a little misleading really, because when you mention printing and computers people always think of computer printers. They think a 3D printer connects to their computers via a USB cable and a power socket. Additive Modelling is a more correct and appropriate term for this process.

A 3D printerThe first part of printing in 3D is to accurately produce a digital representation or model of what you want to create, or print. This is usually achieved by photographing the item from sufficient angles that once the information is digitised, the computer is able to extrapolate the dimensions, detail and shape of the object from any angle. This process is typically best computer controlled, so that exact measurements and details are gathered enabling a 100% digital model to be created.

Although additive modelling has been around for several years, it had only really been used commercially. Midway through the 2000’s open source software projects particularly one called RepRap were developed that bought additive printing out from its entirely commercial domain and into the home hobbyist marketplace. These days, pre designed item templates can be downloaded from the internet that allow users to ‘print’ whatever the template is, for example a funnel or cup etc.

Commercial additive modelling has developed rapidly in the last few years and these days many automotive parts and developments are made using it. Additive modelling printers that work in metal have also been developed. These days many ideas are prototyped as projects using additive modelling.

When To Use Data Recovery

without comments

Even though you can find a number of software programs available out there for data recovery, it is actually not in your best interests to try and recover data from a drive by yourself. If you have a straight forward problem then data recovery software will help. If the problem is something minor to do with a faulty hard disk drive that is giving to problems you can probably get the information you need to recover the data and repair the hard drive yourself from a site like http://data-recovery-tips.co.uk. Be careful though because if you have a serious hard disk fault, you can and most probably will destroy crucial data by attempting to do this all on your own. At times like these,  you should hire an expert to do this for you. It could be very expensive, but as I have said time and again, if you must regain data from your drive, then the cost is worth every penny.

So what might be learnt out of this scenario? Prevention is better than cure! After successful (or unsuccessful) data recovery attempts, you may be asking yourself what you might have carried out to stop the difficulty in the very first place. There’s simply no way round the tiresome task of backing up all of your info! Backing up is something that many folks leave until their hard drives crash and they will have a brush with hard drive recovery. Envision how much time and cash you’ll have saved if you’d backed everything up?!
