Purpose
Three-dimensional (3D) printing is revolutionising tablet fabrication in the field of pharmacy, offering personalised dosing through additive manufacturing techniques such as semi-solid extrusion (SSE). SSE traditionally uses disposable syringes, which pose challenges in temperature control and waste generation.
Methods
This article experimentally simulates various scenarios relevant to pharmacy practice to evaluate the usability of the semi-solid extrusion approach using a first-of-its-kind reusable cartridge. The research assesses the stability of formulations under thermal stress conditions that simulate commercial settings, demonstrating the robust performance of this 3D drug printing method across multiple uses.
Results
This study introduces pharmaceutical-grade stainless-steel cartridges as a sustainable alternative to disposable syringes, enhancing temperature management and reducing waste in SSE 3D printing.
Conclusion
Our findings highlight the potential of reusable cartridges to improve efficiency and sustainability in pharmaceutical manufacturing, with implications for future formulation developments and stability studies. The presented 3D drugprinting approach offers a promising solution for environmentally responsible practices in pharmacy. ...

The Vibe of Skating
Design and Testing of a Vibro-Tactile Feedback System
Providing athletes with real-time feedback on their performance is becoming common in many sports, also in speed skating. This research-by-design project aims at finding a tool that allows the speed skater to get real-time feedback on his performance. Speed skaters often mention a so-called “good feeling” when skating behind a better skater. It is the feeling nearly every speed skater is after when skating alone; skate with less power while maintaining the same speed and feeling of ease. A longer push-off phase at a constant cadence has proven to contribute to this ideal situation but is hard for the coach alone to influence this. Therefore, a system was designed that measures the skating cadence and challenges the skater to change his skating stroke by means of vibro-tactile feedback. Four subjects have tested the feedback system. From this test, we concluded that the system provides meaningful feedback towards changing the skating cycle.
