3D Printing: God Assists In The Plastics Industry

3D printing is a rapid prototyping technology. Based on digital model files, objects can be constructed by layer-by-layer printing, using powdery metal or plastic bonding materials. With the development of time and technology, the application scope and functions of 3D printing technology become more and more extensive and diverse. At present, 3D printing involves aerospace, medical, construction, automotive, electronics, and plastics industries.

3D printing shortens mechanical downtime of plastics

Plastic machinery in operation will inevitably cause damage to some parts, in order to ensure the quality of production and the life of the plastic machinery, it must replace wear parts on time. However, the replacement of mechanical spare parts takes a lot of time, and the production line where the machine is located must also stop working, which inevitably damages the profits of the manufacturer.

3D printing can solve this problem well. Currently, replacing 3D printing with metal parts is not new. Visual First, a 3D operating company in the Netherlands, used fused deposition modeling (FDM) carbon fiber-reinforced polyamide (PA12) thermoplastics to replace its client's The Chocolate Factory metalworking parts, significantly reducing machine downtime and ensuring the company's production line continuity.

Rotate 3D printing to change the direction of fiber arrangement in the material

The application of 3D printing in the plastics industry is also embodied in materials. Plastic materials are versatile and adaptable to a variety of physical and chemical environments. However, they are not omnipotent and must have their own inadequacies. The Lewis Lab of the John A. Paulson School of Engineering and Applied Science at Harvard started with fluids, introduced rotation methods, and developed a new type of rotating 3D printing from nano to macro, controlling the internal structural features of the material system and changing the orientation of the fibers in the material. Provide consistent stiffness for changing materials.

"No distortion" optimized 3D printing wire

Nylon wire has high tensile and wear resistance, so it is popular in the plastics processing industry, but it is easily warped and deformed under hot and humid environment and extrusion conditions. In response, Polymaker, a 3D printing material company, optimized the use of nylon "non-distorting" technology engineering applications.Without compromising the inherent properties of nylon, the use of chemically controlled wire microstructures and crystallization behavior achieves the goal of fully releasing the internal pressure prior to solidification.

3D Printing Filaments Improve Medical Fiber Properties

The medical fiber is a fiber material made of high polymer, and plays an important role in artificial bone, artificial skin, artificial blood vessels, plasma separation, surgical suture and bandaging. Fibre Tuff Medical Biopolymers has developed multifunctional PAPC filaments that can replace polyamides, polyolefins, and cellulose.The company plans to combine this material with smart devices for wearable sensors that measure temperature, blood pressure, exercise, wound infection, and other factors, and send this information to doctors. In the future, this material will likely appear in areas such as extrusion, micro injection molding, bone growth, and surgery.

Facilan? is more suitable for manufacturing processing

The development and utilization of 3D printing technology has spawned many new materials, and the market has brought development space and vitality to the growth of 3D printing materials. Perstorp and 3D4Makers developed FacilanTM, the world's first soft-touch 3D printing material. It is stronger than ABS and is easier to process than PLA. It has excellent surface quality, low warpage, and good layer adhesion. Prints the best-looking parts with the best dimensional accuracy, giving the parts excellent mechanical properties and a luxurious soft touch that meets the most stringent medical and manufacturing requirements.

Photocurable resin material for photocuring 3D printing

Resin is a polymer compound for the processing of plastic products. Its products are highly fluent and bright.At Las Vegas 2018 CES, Formlabs exhibited two new light-curing (SLA) photosensitive resin materials for 3D printing that are ideal for conceptual modeling and functional testing.

New polycarbonate 3D printing material

Covestro partnered with Polymaker to launch new materials for polycarbonate. The material uses Covestro TPU resin, optimized by Polymaker, to achieve its mechanical properties, more robust than traditional TPU resin, comparable to engineering plastics, while having good adhesion, heat resistance, suitable for mold, structure formation And parts and so on.

summary

On August 23, 2015, the State Council Symposium discussed how to speed up the development of advanced manufacturing and 3D printing. The 3D printing industry has developed rapidly, but its growth status is still at the border of “barbarian and civilized”. Standard planning and formulation are weak. However, we cannot ignore the important role that 3D printing plays in the development of industry and technology. Now, more and more industry fields are beginning to integrate 3D printing technology; in the future, 3D printing will further amplify its capabilities and achieve considerable economic benefits.
