Selective Laser Sintering (SLS) was developed at the University of Texas in Austin, by Carl Deckard and colleagues. The technology was patented in 1989 and was originally sold by DTM Corporation. DTM was acquired by 3D Systems in 2001. The basic concept of SLS is similar to that of SLA. It uses a moving laser beam to trace and selectively sinter powdered polymer and/or metal composite materials into successive cross-sections of a three-dimensional part. As in all rapid prototyping processes, the parts are built upon a platform that adjusts in height equal to the thickness of the layer being built. Additional powder is deposited on top of each solidified layer and sintered. This powder is rolled onto the platform from a bin before building the layer
3D printing can be used for: (1) Industrial manufacturing: product conceptual design, prototype production, product review, function verification; Make mold prototype or direct print mold, direct print product. (2) Cultural creativity and digital entertainment: artistic expression carriers with complex shapes and structures and special materials. Part of the characters and props are shaped by 3D printing. The 3D printed violin is close to the level of handicraft. (3) Aerospace, national...
Stereolithography is one of the most widely used additive manufacturing technologies. Stereolithography uses light to cure liquid resin into a solid object, one layer at a time. This offers dimensional freedom and complexity. Stereolithography can be used for a wide variety of applications including functional prototyping and rapid tooling. The technology excels at creating applications with fine features and high detail, as well as a smooth, injection mold-like surface finish. High accuracy...
The 3D printer is a user-friendly and super easy to use 3D printer that helps you turn your imaginary model into something real. 1. It is used in the handicraft industry 1. Improve original design: Obtain design elements quickly through 3D digital means, integrate them into original product design, and save 60% development time; 2. Improve the speed of sculpture and reduce the cost: 3D digitalization can enlarge and shrink the products and then 3D print them out to realize the rapid...
In the silicone products industry, to satisfy the needs of the consumers, multicolor series of silica gel products have been belong to compare a product of sell like hot cakes, but for the production process and cost control, a lot of silicone products processing factory in the production of double color or multicolor types of products, will choose a few to save cost and simpler processing method, As we all know, the molding process is the most common processing method in the silicon rubber...
3D printing in construction encourages using locally available and natural materials. Such practice could help save transportation, construction, and manufacturing energy, as most local materials are processed and installed using less energy. If traditional materials containing toxic chemicals are replaced with natural materials, the toxicity of building environments may be reduced Time and cost reduction A 3D printer can work 24 hours per day, 7 days per week. This means construction projects...
Laser cutting is mainly a thermal process in which a focused laser beam is used to melt material in a localised area. A co-axial gas jet is used to eject the molten material and create a kerf. A continuous cut is produced by moving the laser beam or workpiece under CNC control. There are three major varieties of laser cutting: fusion cutting, flame cutting and remote cutting. Advantages of laser cutting l High quality cut – no finishing l Flexible – simple or complex parts l Non-contact – no...
Stereolithography is one of the oldest types of 3D printing. The process applies laser light to photosensitive polymers (resins) to form models or prototypes under computer controls. The process helps medical device designers and other industrial creators visualize their concepts in three dimensions and refine their ideas as a result. The advantages of stereolithography include flexibility, cost savings, and precision Capabilities Benefits of SLA printing Stereolithography Is Fast...
Plastic 3D printing is one of the fastest and most cost-effective methods available for the iterative design, prototyping, and production of custom parts. Rather than the material being removed from stock, as historically done with subtractive manufacturing processes such as CNC machining, 3D printing works by repeatedly layering small amounts of plastic to build a design from the ground up. Advantages of Plastic 3D Printing • Precision: We use the latest generation of 3D printing technologies...
