3D printing news ICYMI: Leapfrog Bolt prints Polypropylene, new 3D printed spinal implants, more

Mar 11, 2017 | By David | From 3ders

3D printing technology never sleeps, but you do, so here's a helpful recap of things you might have missed in another busy week for the industry:

Leapfrog Bolt 3D Printer prints using Verbatim Polypropylene filament

Perhaps the most successful use of Polypropylene yet in 3D printing was this week achieved by materials expert Verbatim, using the Leapfrog Bolt 3D printer. PP is a commonly used plastic, but one that hasn’t yet been integrated into a 3D printing project without difficulties. Although it has impressively high chemical resistances and mechanical properties, making it a material with a lot of potential for 3D printing applications, it isn’t used regularly as it tends to warp in most 3D printers.

Leapfrog 3D’s latest Bolt 3D printer is one of the only machines on the market that uses a Direct Drive and Independent Dual Extruder system. Because of this superior heat regulation, the Bolt was able to successfully print with PP without any warping of the material. As the company boasts, it is yet to come across a filament that the Bolt can’t print. The results of this collaboration between Leapfrog and Verbatim were exhibited at the 2017 RapidPro show in the Netherlands.

Pharmacy researchers at UCL to carry out tests on 3D printed tablets

Researchers at UCL have called for participants in a new study that will examine the effectiveness of different 3D printed pills. The study will hopefully provide information about the optimum shapes and dimensions for tablets to minimize discomfort or fear of choking when swallowing. A variety of tablets of different shapes and sizes have been produced through 3D printing techniques, to be tested by participants. Some shapes can make medicine intake easier and safer, however scientific data on the end user acceptability is required to adapt the shapes to the needs of specific patient groups. The research is intended to make the taking of medication easier for patients, particularly children and the elderly.

During the test session, you will be asked to assess ten 3D-printed shapes. Researchers will ask you to perform the following tasks: open 2 different types of packaging, pick 10 different shapes of 3D-printed pills and swallow 5 different shapes of 3Dprinted pills with the aid of water.

Then we will ask you to rate your satisfaction using scales and questions. During the test your hands will be video recorded. The shapes you will be given are made of perfectly safe ingredients (also used in foods) and do not contain any drugs.

If you are a healthy adult aged 18 to 50 years you are eligible to take part in the study.

The study will take place at UCL School of Pharmacy, 29-39 Brunswick Square, London WC1N 1AX. You will be asked to attend one session which will last 60  minutes (approximately). You will be paid £5 as compensation for your time.
