The main benefit of 3D printed is the reduction in cost. The majority of savings come from the reduction in high machining costs. Typically a grip or fixture would be sent away to be machined by a highly skilled operator on a CNC machine over a number of days. With 3D printing, once the design of a 3D model is complete the file is sent electronically to the nearest printer, quickly analysed and printed on machine that requires very little human interference. Grips and jigs made via 3D printing are also produced with much cheaper materials compared to traditional grips and fixtures further reducing the cost.
The other main benefit of 3D printed grips and fixtures is the speed at which they can be produced. Machining of complex metal geometries takes significant planning and highly skilled CAM designers and machine operations. This can result in the lead time for CNC machining taking days or even weeks before a part is completed. By using 3D printing to replace an aluminium assembly tool (see image below), a well-known car manufacturer was able to cut lead time by 92% from 18 days to 1.5 days.
3D printing offers a vast range of materials over a range of technologies. Engineering material properties such as chemical resistance, flame retardancy, heat resistance and UV stability are now widely available in the 3D printing industry. Parts can be produced or finished in many colours and surface finishes. The polymeric materials used in 3D printing also mean that damage to parts (that come in contact with the grip or fixture) is limited during handling and assembly when compared to more traditional metal fixtures
Grips and fixtures are regularly manipulated by workers. The majority of the materials used in 3D printing are lighter than aluminium reducing the load on workers and improving safety. Industrial FDM parts are not printed solid but rather filled with infill further reducing the weight of parts.
The speed that 3D printing can produce parts gives designers much more freedom to optimise a design through several iterations. 3D printing technologies also allow for complex and ergonomic designs to easily be produced improving worker interaction and comfort.
Several 3D printing technologies are able to produce to a high level of accuracy (Industrial FDM - ± 0.2 mm, SLA - ± 0.05 mm and SLS - ± 0.1 mm). SLA and SLS can also produce fine and intricate details as well as functional connections like snap fits and interlocking features.
3D printers and great variety of printing materials make you create models with different features that can undergo testing even in tough conditions. This gives you a chance to try out not only the shape and ergonomics of your model but also its resistance in the real environment.
The individualized nature of health care means that AM is an ideal solution for the medical industry. Rather than manufacture thousands of identical components, AM enables the creation of prosthetic and orthotic devices tailored to a patient's specific anatomy improving their effectiveness.
Where in the past, traditional manufacturing may have struggled to create complex, organic shapes, the designs that AM technologies are now able to print are potentially limitless. Thin scaffolds that perfectly follow the contour of a bone or porous metal parts are easily manufacturable opening the door to many applications and designs that were not previously possible (including facial bones, radius and ulna).
Lead times to create tooling, whether in-house or outsourced, can be lengthy and expensive. One of the hallmarks of AM is that is provides designers and engineers the tools to quickly create and iterate designs, communicate more effectively using realistic prototypes and ultimately reduce time to market. An essential part of the success of any medical device is the feedback from physicians and patients and the speed these design improvements can be implemented at. Within a matter of hours it is now possible to iterate the design of a medical tool based on direct feedback from the surgeon who will use it and print a new prototype for evaluation. The fast feedback loop accelerates design development. Manufacturers can also use early AM parts to support clinical trials or early commercialization while the final design is still being optimized
The ability to produce patient - specific parts directly from scan data is an obvious benefit that is not cost - effective with most conventional manufacturing techniques. These tailored parts are made possible through software that converts the patient's own scans (using techniques like computerized tomography (CT), magnetic resonance imaging (MRI) and laser scanning) into 3D files. These files essentially encode each patient's specific anatomic or pathologic features, which then can be fabricated by 3D printers.
While much of the focus for 3D printing in the medical industry has been around implants and medical devices used by patients, one of the largest areas of application has concentrated on anatomical replicas. Historically, clinical training, education and device testing have relied on the use of animal models, human cadavers, and mannequins for hands-on experience in a clinical simulation. These options have several deficiencies including limited supply, expense of handling and storage, the lack of pathology within the models, inconsistencies with human anatomy, and the inability to accurately represent tissue characteristics of living humans.
AM's ability to produce fine mesh or lattice structures on the surface of surgical implants can promote better osseointegration and reduce rejection rates. Biocompatible materials such as titanium and cobalt - chrome alloys are available for applications in maxillofacial (jaw and face) surgery and orthopedics. The superior surface geometry produced by AM has been shown to improve implant survival rate by a factor of 2 when compared to traditional products. The porosity of these AM products coupled with the high level of customization and ability to manufacture them from traditional medical materials has resulted in AM implants becoming one of the fastest growing segments of the AM medical industry.
3D printing technologies are able to produce parts to a high accuracy with excellent surface finish. This property, coupled with temperature resistance and design freedom mean that 3D printed molds are now a viable method for low-run production injection molding. 3D printed molds also allow verification of injection mold designs before investing in expensive metal molds.
AM is also being used in the manufacture of low cost prosthetics. The collaborative nature of the AM industry has meant that a quick internet for 3D printed prosthetics reveals a huge range of peer-reviewed products that can be printed on desktop AM printers at a very low cost. These designs can easily be scaled or altered to perfect match the size of the user. The e-NABLE Community comprises of a group of individuals from all over the world who are using their 3D printers to create free 3D printed hands and arms for those in need of an upper limb assistive device. Concepts like this are now becoming more commonplace as AM continues to move into the mainstream.
Typically, traditional manufacturing techniques and materials are used to produce the structural section of functional prosthetics. AM is often then implemented at the interface section by producing complex contours that fit perfect to the users anatomy improving comfort and fit. AM is also implemented on the external outer surface of prosthetics to produce life-like and organic outer shells that hide the mechanical nature of prosthetics. This also allows the wearer to fully customize their prosthetics to whatever design or style they prefer.
Easy to discuss a design It's with clients and fit test the design. Easily translate the client's wishes into a 3D printed model you can touch.Testing ideas and fast iterations lets you discover what works and what doesn't with no cost penalties. Recreating textures and finishes adds a new dimension. Verify designs before investing in expensive molding tools.
You might not have access to a real fossil or rare insect species, and a field trip to the ancient ruins described in your textbook may be outside the budget, but you can 3D print a model of just about anything! Design your own models, or save time by printing existing files from libraries like My Mini Factory, Thingiverse, Yeggi.
You can print new models in a matter of hours, so it's easy to respond directly to student curiosity, instead of being limited by what you ordered ahead of time. What if you could make a visual example for any one of your pre-existing lessons? What if you could make 40 of them that each student could take home and study?
The impact of laser marking has been more pronounced for specially designed "laserable" materials and also for some paints. These include laser - sensitive polymers and novel metal alloys.
The term laser marking is also used as a generic term covering a broad spectrum of surfacing techniques including printing, hot-branding andlaser bonding. The machines for laser engraving and laser marking are the same, so that the two terms are sometimes confused by those without knowledge or experience in the practice.
