“…This layer-by-layer approach enables the direct production of 3D parts from a CAD model. Currently, 3D printing technology, particularly FDM, is extensively used for mass customization and fabrication of open-source design across numerous applications, including agriculture, healthcare, automotive, locomotive, and aviation [11][12][13][14]. Moreover, amidst the Coronavirus disease 2019 (COVID-19) pandemic, 3D printing has emerged as a critical tool in enhancing healthcare and our overall response to the crisis.…”

Additive manufacturing, commonly known as 3D printing technology, has become one of the mainstream processes in the manufacturing industry due to its advantages over conventional manufacturing, which have piqued the public's interest. This study aims to focus on the influence of thermal conditions on crystallization towards mechanical properties of 3D printed poly(lactic) acid (PLA) degradation samples with 100% infill. As for the degradation profile, the highest weight loss recorded by the samples was 0.7%, observed in samples buried in soil with an abiotic medium for one month. The exposure of degraded samples to high temperature during drying affected their crystallinity, resulting in significant changes in strains, particularly between week 1 and week 2, where strains dropped significantly from 7.33% to 4.28%, respectively. In conclusion, it has been demonstrated that degradation for PLA material still can occur in an abiotic medium, albeit at a slower rate compared to a biotic medium due to the presence of additional microorganisms and bacteria. Besides, the post-heat treatment process on PLA degradation samples affects their crystalline structure, resulting in significant changes in mechanical properties, particularly especially strains. Therefore, it can be concluded that different materials exhibit distinct mechanical properties.

“…3D printing could bring a new innovative way to produce singleuse sensors. The advantages of 3D printing are its low cost, good repeatability, and ease of changing some feature dimensions or geometries in the prototyping stage by simply changing instructions via the 3D printer's software [15]. However, many aspects, such as the availability of suitable durable materials and reaching a required surface quality are relevant open questions yet to be studied.…”

Three-dimensional (3D) printing has a high potential in various biomedical applications. We hypothesise that 3D printing could be a viable option to construct bioimpedance spectroscopic (BIS) sensors suitable for electrochemical characterization of oral mucosal tissues. Previous BIS studies have been relied on hand-made probes possessing significant limitations related to single patient disposable use, great inter-probe differences and weak reproducibility of measurement. There is also uncertainty related to effect of varying loading pressure between the probe and biological tissue. Here, we introduced three different sized rectangular shaped 3D printed probes and test those using four-terminal measurement principle on various porcine oral tissue samples. We found that constructing fully 3D printed probe is a challenging task and prone to issues relating to short circuiting or electrochemical corrosion. However, our final protype version constructed with silver-coated copper electrodes showed favourable characteristics in BIS experiments. All three different sized probes were able to differentiate between different tissue types with excellent reproducibility. The effect of loading pressure was found to be almost negligible when using small and medium sized probes. However, further studies are needed to measure tissues with uneven surfaces, such as palatinum, and to avoid manual or electrochemical surface finishing steps.
