3D Printing for Custom Made Labware

3D printing is an exciting and rapidly expanding technique that could become more and more involved in the world of chemistry. For example, a nature paper (Symes et. al, 2012) reported a reaction in which all specialized equipment was custom built using 3D printing, controlling the outcome by printing reagents into reaction vessels. This creative application opens doors to smaller laboratories and enterprises that would previously only be possible with ‘expensive chemical engineering technologies’.

So how does this link in with sustainability? While it can do some amazing things, it can be applied more simply to create custom-made items which are uncomplicated to design. 3D printing can be used as a way around purchasing expensive equipment, often resulting in large savings on transport costs and using fewer raw materials.

An example of this was demonstrated by Blue Carter – a member of Dr Jon Kitchen’s group. He needed to analyse a solid sample, but the slots in the rack of the fluorescence spectrometer are usually designed for cuvettes filled with solution; solid sample slides won’t fit.

Instead of replacing the entire rack, the slide was mounted onto a 3D-printed ABS plastic holder which fits perfectly into the cuvette holder for solutions. For this particular printer / material, it cost around 2p per holder and under 4 minutes per holder on average (30 minutes per print-job with 8 holders made at once).

Blue’s slide holders were printed using a friend’s machine, but the University actually has several 3D printers of its own. Dr Peter Birkin’s group in electrochemistry are another example of how this has been put to good use – they create bespoke pieces of equipment such as air-sensitive X-ray cells and holders similar to Blue’s.

If others in the department were to use this technology in similar ways, it could be part of a movement towards a more sustainable, savvy and self-reliant chemistry, less dependent on suppliers for its needs.

Key facts:

  • The most common materials are the thermoplastics ABS and PLA.
  • Numerous other materials have been used including glass, metal, wood composite, and even chocolate! However, usually each printer supports only certain materials.
  • 3D printers vary in cost, with the cheapest at around £350 and the most expensive in the thousands. If you need one-off pieces of equipment printed, you may wish to contact others in the department to use theirs.
  • Below is a video, showing how the technology works:

    Since the initial test prints of the solid state fluorescence holder the Kitchen Group have invested in a 3D printer of our own! We hope to update the blog with some photos showing what we’ve created/printed soon.
