Choosing a 3D Printer for your School

3D printing is fast becoming the new must-have technology for schools. After-all, what could be more exciting for students (and teachers!) than watching their 3D designs come to life at the push of a button? But if you’re thinking of acquiring a 3D printer, there are several key factors you should take into consideration when choosing the best model for your school.

Print size:

Firstly, you may want to consider the size of the prints you are looking to create. There are a number of entry level compact 3D printers available, but it is worth noting that these will have a significantly smaller build volume compared to larger, desktop 3D printers which can print from approx.. 10cms high, upwards.

Layer resolution:

It is also important to compare the layer resolution each 3D printer provides. Without getting too technical, layer resolution refers to the height of each of the plastic layers that make up the printer 3D model and it is measured in microns. One micron is one millionth of a metre. Therefore, the lower the number of microns, the better the resolution of a print. Some desktop 3D printers have a layer resolution as high as 20 microns which may not mean much at first, but if you take into consideration that a human hair is typically 90 microns in diameter, you will soon realise just how incredibly small each layer really is!

Ease of use:

Ease of use is an important factor to consider too. As whilst some 3D printers work straight out of the box, or require a small amount of calibration which the 3D print software guides you through, others need to be fully calibrated before use which isn’t always an easy or quick task.

Print material:

The material the printer uses to print with – also known as filament – is another element to think about. The majority of printers print using PLA, a form of polyester that’s made from a variety of natural sugars, so it’s safe for children. However, other 3D printers can print using a range of other materials, including ABS. ABS is stronger and has a higher melting point so it’s less likely to deform under high heat than PLA, but it is worth noting that it emits fumes during printing.

Number of nozzles:

Some printers feature just one printing nozzle (print head), which does limit prints to being printed in one colour. Yet some 3D printers feature a dual nozzle, meaning prints can be printed in two colours or using a dissolvable support material so more complex prints can be produced.

Connectivity:

You may want to consider how you would like to connect to your 3D printer. Whilst some offer an array of options, including WIFI, USB, Ethernet and SD Card, others are more limited and just offer connection via an SD Card for example.

Aftercare:

Lastly – and often overlooked, it’s important to think about the aftercare of your 3D printer. As with all new technology, there are bound to be a few hiccups along the way and maybe even the need for repair. The majority of printers come with warranties – but these are often return to base, meaning you need to ship the printer back to the manufacturer or supplier in order to get it repaired. By choosing a 3D printer that includes an onsite warranty, there is nothing to worry about. You have peace of mind knowing you have someone at the end of the phone to answer any questions you may have, not to mention the relief of knowing you won’t be caught out by unexpected repair costs.
