“…This work produced a highly stretchable silicone (elongation to break of 2000%), which could be printed in high speed leading to the potential application in the direct 3D printing of robust silicone prosthetics. Zhao et al (2019) recently introduced photo curable approach for direct 3D printing silicone using a digital light projector (DLP) ceramic 3D printer and novel formulations of photosensitive silicone resins (Zhao et al, 2019). In this work, they produced a series of photoresins using different content of reinforcing filler silica particles and photoinitiators, resulting in DLP 3D printable silicone elastomers that have tunable mechanical properties and hardness.…”

Physical disfigurement due to congenital defects, trauma, or cancer causes considerable distress and physical impairment for millions of people worldwide; impacting their economic, psychological and social wellbeing. Since 3000 B.C., prosthetic devices have been used to address these issues by restoring both aesthetics and utility to those with disfigurement. Internationally, academic and industry researchers are constantly developing new materials and manufacturing techniques to provide higher quality and lower cost prostheses to those people who need them. New advanced technologies including 3D imaging, modeling, and printing are revolutionizing the way prostheses are now made. These new approaches are disrupting the traditional and manual art form of prosthetic production which are laborious and costly and are being replaced by more precise and quantitative processes which enable the rapid, low cost production of patient-specific prostheses. In this two part review, we provide a comprehensive report of past, present and emerging soft-tissue prosthetic materials and manufacturing techniques. In this review, part A, we examine, historically, the ideal properts of a polymeric material when applied in soft-tissue prosthetics. We also detail new research approaches to target specific tissues which commonly require aesthetic restoration (e.g. ear, nose and eyes) and discuss both traditional and advanced fabrication methods, from hand-crafted impression based approaches to advanced manufactured prosthetics. We discuss the chemistry and related details of most significant synthetic polymers used in soft-tissue prosthetics in Part B. As advanced manufacturing transitions from research into practice, the five millennia history of prosthetics enters a new age of economic, personalized, advanced soft tissue prosthetics and with this comes significantly improved quality of life for the people affected by tissue loss.

“…Up to now, the thiol-ene chemistry approach resulted effective to vulcanize diene-rubbers both in latex and in solid film state whereas, however, there are few researches investigating the photo-crosslink of rubbers. Very recent efforts in 3D printing of hydrocarbon elastomers have been proposed by Scott et al [16] as well as UV-induced crosslinking of liquid silicone rubber to tune the 3D printed part mechanical properties [17,18]. Moreover, Patel et al [5] developed resin formulations based on epoxy aliphatic acrylate and aliphatic urethane diacrylate diluted with isobornyl acrylate to obtain highly stretchable and UV curable elastomers for DLP.…”

Mechanical performance of 3D printed 'Rubber-like' commercial resins are not comparable to typical vulcanized diene rubbers since they show lower strain at break. In the present work, samples made of liquid butadiene rubber have been photocured by thiol-ene chemistry and 3D printed. Morphological features and mechanical properties have been investigated by means of scanning electron microscopy (SEM), dynamic mechanical analysis (DMA) and tensile tests. The 3D printed samples show the characteristic mechanical properties of unfilled diene rubbers reaching a strain at break up to 400%.

“…Three‐dimensional (3D) printing, which fabricates objects through adding materials layer by layer under computer control, has spurred considerable attentions for its unique advantages, such as high flexibility, efficiency and customizable fabrication, especially for small quantities of parts with complicated structures, which are not available through conventional manufacturing methods 1‐8 . Depending on different printing principles, there have been over 50 printing technologies and can be classified into seven categories: powder bed fusion, vat photopolymerization, material jetting, material extrusion, binder jetting, sheet lamination and energy deposition 7,9‐15 .…”

3D Printing has become a powerful technology for future advanced manufacturing, however the choice of materials with good performance is still limited. In this research, a type of hybrid photopolymer resin based on silicone epoxy with high UV curing rate and low viscosity was applied in stereolithography (SLA) technology. First, aliphatic silicone epoxy was synthesized through hydrosilylation reaction, and then compounding with acrylates, cycloaliphatic epoxy and photo‐initiators, finally the hybrid photopolymer system for SLA was obtained. The features of UV curing process were studied through photo‐differential scanning calorimetry and real‐time Fourier transform infrared measurements. Scanning electron microscopy test showed interpenetrating polymer network structure was formed in 3D objects. The performances of 3D printed sample such as mechanical properties, thermal mechanical and stability properties were also investigated in detail. Moreover, the 3D printed objects with complicated structures showed high printing accuracy. This new type of hybrid photopolymer system based on aliphatic silicone epoxy was with fabrication ease, good mechanical properties, good thermal stability and high printing resolution and has great potential of applications in industrial design and models making fields.
