3D Printed Meat: Revolutionizing Manufacturing The Surge of 3D Printing and Its Transformative Effects
Using 3D printing, it's possible to print a variety of materials including plastic, metal, nylon, ceramic, and concrete. There are different types of 3D printing technologies that work in different ways to print 3D objects.
Fused Deposition Modeling (FDM)
Fused deposition modeling is one of the most commonly used 3D printing processes for modelling and prototyping. An FDM 3D Printed Meat heats and extrudes thermoplastic filament, such as PLA or ABS, through a movable extruder head. The extruder deposits ultra-thin layers of heated plastic onto a build platform, where it cools and hardens into solid plastic. Each subsequent layer bonds to the previous as extrusions are placed on top of each other, producing a 3D printed object from digital model data layer by layer. FDM printers are relatively inexpensive and suitable for printing functional models, prototypes, and production parts in durable thermoplastics.
Selective Laser Sintering (SLS)
Selective laser sintering works by using a laser to fuse small particles of plastic, metal, ceramic, or glass powders into a mass that has the desired 3d shape. In an SLS machine, a thin layer of powder is rolled or spread across the build platform inside the enclosed build chamber. Then, a high-powered laser beams traces the cross-section patterns for each layer onto the powder surface, fusing the particles together. After one layer is complete, the build platform lowers slightly and a new layer of powder is rolled onto the surface. The laser repeats the process, fusing new powder to the layer below. Once the full part has been scanned, the non-solidified powder is removed, leaving only the finished 3D printed model. SLS printers can produce parts with strong, durable materials like nylon and metal.
Material Jetting
Material jetting 3D printing works by depositing photopolymer materials through inkjet-style print heads. A digital light processing (DLP) projector selectively cures each ultra-thin layer of liquid photopolymer as it is jetted onto the build platform. The print heads deposit distinct materials for different parts, features, or color-combinations, resulting in multi-material and multi-color models. Objects printed with material jetting offer smooth surfaces, high resolution details, and the ability to produce multiple materials simultaneously for appearance models or aesthetic applications. Due to their ability to achieve surface finishes akin to injection molding, material jetting 3D printers are well-suited for producing jewelry, dental models, and other detailed objects.
Impact on Manufacturing and 3D Printed Meat
Mass production using 3D printing, also known as additive manufacturing, has the potential to revolutionize manufacturing by offering more flexible production processes without the high costs of traditional manufacturing. With 3D printing, manufacturers can produce customized products on demand by printing only what is needed and when it is needed, eliminating the overproduction and waste inherent in mass production processes. On-demand 3D printing also reduces the need to maintain large inventory stock levels.
Another opportunity enabled by 3D printing is the ability for distributed manufacturing—making parts near the point of use. This can reduce shipping and transportation costs while also allowing greater responsiveness by offering shorter delivery lead times. Complex supply chains and logistics may be simplified since it is possible to produce parts locally versus shipping stock from a centralized factory. Distributed on-demand manufacturing introduces efficiencies and resiliency into supply chains.
For prototype development and product development processes, 3D printing accelerates design-validation cycles by rapidly producing custom models, fittings, and assemblies from digital designs. Engineers can test multiple design iterations quickly through print-test-redesign loops, optimizing products faster and reducing time-to-market. 3D printed tools and fixtures speed production ramp-up and changeovers when rolling out new manufacturing processes as well.
New Business Models and Mass Customization
3D printing is enabling new economic models and business opportunities that leverage mass customization. Digital manufacturing allows for more flexible batch sizes down to the individual product level, unlocking market opportunities for customized products. Manufacturers can offer customers a breadth of options to personalize products to their tastes and requirements without incurring high costs of setup like traditional mass production.
Digital inventory and 3D printable designs give rise to compelling new business models like using digital design marketplaces to buy and sell downloadable 3D models of products. Product designers and small manufacturers can access new online markets by publishing digital blueprints for others to 3D print. Design-on-demand services let customers upload custom CAD models that are produced using additive techniques.
Online configurators and personalization marketplaces let customers virtually build and design custom products themselves from a catalog of modular parts before ordering for fabrication via 3D printing. New forms of mass customization unlock the ability for each product to be unique to the individual.
Impact on Healthcare and Bioprinting
3D printing is also having disruptive impact on the healthcare industry through bioprinting of tissues and organs. Scientists are developing techniques to print biomechanical scaffolds as well as living cells and tissues layer-by-layer to research regenerating organs and tissues. Bioprinted skin and cartilage grafts have already helped burn victims and patients with defective joints. Researchers are also investigating ways to 3D print whole human organs using a "body on a chip" approach.
These developments could help address shortages of donor organs and tissues by enabling lab-grown transplants. Custom implants and prosthetics made through 3D printing offer personalized fits that improve patient outcomes. 3D printed drugs can be used to develop personalized medicines tailored to an individual's genome for maximum efficacy. Additive manufacturing techniques even allow surgical guides and anatomical models to be fabricated on-demand for pre-surgery planning and simulation of complex procedures. Overall, 3D bioprinting offers tremendous potential to transform healthcare delivery and treatment options in the coming decades.
Additive manufacturing techniques like 3D printing have significant potential to revolutionize industries from manufacturing to healthcare by offering on-demand customization, distributed manufacturing, and new business models leveraging mass customization and digital design marketplaces. Utilizing 3D printing shifts production frameworks from economies of scale towards economies of one, unlocking more flexible and distributed systems. Though additive manufacturing is still developing, the ongoing progress and falling costs of 3D printing indicate it will continue disrupting traditional production processes across many domains in the coming years.
