Biobased Acrylate Photocurable Resin Formulation for Stereolithography 3D Printing

Abstract

To facilitate the ongoing transition toward a circular economy, the availability of renewable materials for additive manufacturing becomes increasingly important. Here, we report the successful fabrication of complex shaped prototypes from biobased acrylate photopolymer resins, employing a commercial stereolithography apparatus (SLA) 3D printer. Four distinct resins with a biobased content ranging from 34 to 67% have been developed. All formulations demonstrated adequate viscosity and were readily polymerizable by the UV-laser-based SLA process. Increasing the double-bond concentration within the resin results in stiff and thermally resilient 3D printed products. High-viscosity resins lead to high-resolution prototypes with a complex microarchitecture and excellent surface finishing, comparable to commercial nonrenewable resins. These advances can facilitate the wide application of biobased resins for construction of new sustainable products via stereolithographic 3D printing methods.

Assessing relations between Circular Economy and Industry 4.0: a systematic literature review

“…Some scholars discussed the exploitation of AM for upgrading current recycling processes -through either new sustainable (Clemon and Zohdi 2018;Mandil et al 2016;Sauerwein and Doubrovski 2018;Woern et al 2018;Zhong and Pearce 2018) or networks (Santander et al 2018)and digitalising the manufacturing process, for example, through a new kind of process (Dutta et al 2001) or managerial strategies (Unruh 2018). Others presented the idea of using AM to support the remanufacturing of products or components (Lahrour and Brissaud 2018;Leino, Pekkarinen, and Soukka 2016), the development of CBMs focused on recycled materials (Mattos Nascimento et al 2018); (Millard et al 2018), the exploitation of biomaterials (van Wijk and van Wijk 2015;Voet et al 2018), or the reuse of products/materials (Bloomfield and Borstrock 2018).…”

“…BDA, instead, was seen as a good solution for either developing automated approaches assessing potential value pathways for secondary materials (Davis, Aid, and Zhu 2017;Jose and Ramakrishna 2018) or discovering potential industrial symbioses (Song et al 2017). AM can be useful in terms of exploitation of biomaterials (van Wijk and van Wijk 2015;Voet et al 2018). Furthermore, simulation techniques can be exploited for calculating a set of eco-efficiency indexes (Rönnlund et al 2016).…”

Photocross‐linked polymers based on plant‐derived monomers for potential application in optical 3D printing

“…Lee et al investigated the conversion of acrylic and vinyl groups and determined, that only after ∼ 85% conversion of acrylate double bonds was reached, did vinyl double bonds began to react and form a highly crosslinked network. Thus, due to the high reactivity, acrylates are one of the most common materials in optical 3D printing …”

3D Printing and Digital Processing Techniques in Dentistry: A Review of Literature

“…The scope of application has gradually extended to lost wax castings and the production of resin models for temporary crown bridges. Additive manufacturing through SLA or DLP process is applicable for high‐resolution prototyping and manufacture of bio‐medical apparatus, such as dental implants and patient‐specific scaffolds for tissue regeneration …”
