Techniques and Software Used in 3D Printing for Nanomedicine Applications

Emerging Additive Manufacturing Methods for Wearable Sensors: Opportunities to Expand Access to Personalized Health Monitoring

“…Binder jetting, powder bed fusion, and directed energy deposition are commonly employed in aerospace, medical, and defense sectors for fabricating intricate metal components. [32,[59][60][61] Although AM holds transformative potential for the creation of wearable devices with unprecedented levels of design freedom and customization capabilities, at present only a select subset of these printing methods is compatible with the processing requirements of wearable sensors.…”

“…The op-portunities afforded by the rapid, on-demand, facile manufacture of intricate, sophisticated, and highly customized sensors eliminates traditional cost barriers to device innovation. [32,33,58,59] In the sections that follow, we highlight recent progress in deploying AM to fabricate wearable sensing platforms. We restrict the scope of our focus to exemplars that utilize AM techniques produce a finished, working component, such as a functional sensing module [73,74,76,86,96,120] or the structural/defining elements of a wearable platform [30,72,75] (e.g., microfluidic channels), in contrast to supporting (i.e., soft lithographic molds) or cosmetic elements [77,87] (e.g., nonactive wristbands/straps).…”

3D Bioprinting Technology – One Step Closer Towards Cardiac Tissue Regeneration

“…They also play an important role in stem cell differentiation into cardiomyogenic phenotype (Zhang et al, 2016). In Tissue engineering, scaffold (hydrogel) materials should support cell adhering, cell proliferation along possessing key attributes like printability, degradation kinetics, biocompatible and material biomimicry (Table 2) (Murphy and Atala, 2014;Sahai and Gogoi, 2019). Hydrogels that are currently used in the cardiac regenerative medicine are either naturally derived polymers (like alginate, gelatin, collagen, chitosan, fibrin and hyaluronic acid) or synthetic molecules (polyethylene glycol, PEG) (Murphy and Atala, 2014;Sun et al, 2012;Spiller et al, 2011).…”

A review on the surface modification of materials for 3D-printed diagnostic devices

“…Plastics, especially thermoplastics, include polymers such as Acrylonitrile Butadiene Styrene (ABS) and Polylactic Acid (PLA), where both are used in the FDM method to form the 3D object through the deposition of successive layers. 15,16 These materials have been used extensively in the domain of diagnostic devices specially for biosensing applications including DNA sensing. 17,18 The modication of these materials and their surfaces helps to tag/conjugate desired functional groups that will help to detect the biomarkers and bioreceptor elements.…”
