“…In recent years, three-dimensional (3D) printing, also known as additive manufacturing, has emerged as a technology that uses computer-aided design (CAD) for layer-on-layer fabrication, having many advantages over traditional technologies [193][194][195]. Low cost and endless design possibilities have made this approach very interesting for prototyping in many fields, including process design, aerospace engineering, biomedicine, and catalysis [196,197].…”

The market for industrial enzymes has witnessed constant growth, which is currently around 7% a year, projected to reach $10.5 billion in 2024. Lipases are hydrolase enzymes naturally responsible for triglyceride hydrolysis. They are the most expansively used industrial biocatalysts, with wide application in a broad range of industries. However, these biocatalytic processes are usually limited by the low stability of the enzyme, the half-life time, and the processes required to solve these problems are complex and lack application feasibility at the industrial scale. Emerging technologies create new materials for enzyme carriers and sophisticate the well-known immobilization principles to produce more robust, eco-friendlier, and cheaper biocatalysts. Therefore, this review discusses the trending studies and industrial applications of the materials and protocols for lipase immobilization, analyzing their advantages and disadvantages. Finally, it summarizes the current challenges and potential alternatives for lipases at the industrial level.

“…They are abundant in nature and many of them have a complex structure made up of numerous intramolecular and intermolecular hydrogen bonds. The most representative components of this class are cellulose, lignin, chitosan, starch and alginate [7]. Polysac charides as reinforcement agents were employed as pure fibers (e.g., cellulose, lignin or hemicellulose) or as a mixtures extracted from plants (e.g., flax, bamboo, hemp) in which they are the main constituents.…”

“…Three-dimensional (3D) printing, or additive manufacturing, is an innovative method to produce a three-dimensional object using different processes and raw materials, such as resins and powder grains, generally building a product layer by layer [1]. The invention of 3D printers in 1986 has marked a turning point in different fields, including pharmaceutics [2], engineering [3], agri-food [4,5] and medicines [6,7]. The rapid manufacturing times and the easy process with the computer-assisted design (CAD) are key to 3D printing's increasing success [8].…”

An Overview of Natural Polymers as Reinforcing Agents for 3D Printing

Three-dimensional (3D) printing, or additive manufacturing, is a group of innovative technologies that are increasingly employed for the production of 3D objects in different fields, including pharmaceutics, engineering, agri-food and medicines. The most processed materials by 3D printing techniques (e.g., fused deposition modelling, FDM; selective laser sintering, SLS; stereolithography, SLA) are polymeric materials since they offer chemical resistance, are low cost and have easy processability. However, one main drawback of using these materials alone (e.g., polylactic acid, PLA) in the manufacturing process is related to the poor mechanical and tensile properties of the final product. To overcome these limitations, fillers can be added to the polymeric matrix during the manufacturing to act as reinforcing agents. These include inorganic or organic materials such as glass, carbon fibers, silicon, ceramic or metals. One emerging approach is the employment of natural polymers (polysaccharides and proteins) as reinforcing agents, which are extracted from plants or obtained from biomasses or agricultural/industrial wastes. The advantages of using these natural materials as fillers for 3D printing are related to their availability together with the possibility of producing printed specimens with a smaller environmental impact and higher biodegradability. Therefore, they represent a “green option” for 3D printing processing, and many studies have been published in the last year to evaluate their ability to improve the mechanical properties of 3D printed objects. The present review provides an overview of the recent literature regarding natural polymers as reinforcing agents for 3D printing.

“…Applications of hydrogel actuators in micro-swimmers, wearable devices, and origami structures, were discussed. N. Li et al reviewed 3D printing technology used for printing biopolymers, i.e., polysaccharides and proteins [ 34 ]. The most commonly used printing mechanisms, including inkjet and extrusion-based printing, stereolithography, selective laser sintering, and binder jetting, were discussed.…”

Wounds are a major health concern affecting the lives of millions of people. Some wounds may pass a threshold diameter to become unrecoverable by themselves. These wounds become chronic and may even lead to mortality. Recently, 3D printing technology, in association with biocompatible hydrogels, has emerged as a promising platform for developing smart wound dressings, overcoming several challenges. 3D printed wound dressings can be loaded with a variety of items, such as antibiotics, antibacterial nanoparticles, and other drugs that can accelerate wound healing rate. 3D printing is computerized, allowing each level of the printed part to be fully controlled in situ to produce the dressings desired. In this review, recent developments in hydrogel-based wound dressings made using 3D printing are covered. The most common biosensors integrated with 3D printed hydrogels for wound dressing applications are comprehensively discussed. Fundamental challenges for 3D printing and future prospects are highlighted. Additionally, some related nanomaterial-based hydrogels are recommended for future consideration.
