Market Dynamics
Drivers
This section describes the major factors influencing the global Best 3D printing solutions market, including drivers, restraints, challenges, and opportunities.
Production of customised products is easy.
The best 3D printing solutions allows you to create custom items based on your specific needs and specifications. While 3D printing is still mostly used for prototyping because it eliminates scrap and reworks, the trend is now turning toward the production of usable parts and tooling equipment. Due to the ability to produce complex designs without the need for special knowledge, the best 3D Printing Solutions often allows manufacturers to conduct critical trial and error processes for physical objects.
Manufacturing costs and process downtime are reduced.
Since 3D Printing Solutions can minimise the time it takes to design and manufacture usable components, prototypes can be produced quickly without having to reconfigure or retool the manufacturing line. Best 3D printing solutions removes the need for costly tool manufacturing for low-to-medium volume applications, resulting in lower prices, lead times, and labour.
Investments by the government in 3D printing ventures
Governments around the world are launching programmes and providing grants to educational institutions, research centres, and research and technology organisations in order to better understand and promote the use of 3D printing technology. Global initiatives for encouraging university-level 3D printing research have been introduced in countries such as the United States, the United Kingdom, and Canada, which is driving technological development and the establishment of start-ups. The development of new applications for the best 3D printing technologies has piqued the interest of industrialists and governments all over the world.
New industrial-grade 3D printing materials are being developed.
The materials that are used in 3D printing are just as critical as the printers themselves. Metals, ceramics, and even biocompatible materials are now being made available for 3D printing. Polymers were once the most widely used materials in 3D printing. The creation of new materials for Best 3D Printing Solutions will help 3D printing methods broaden their application field into niche sectors like printed electronics and the energy and power industries.
Restraints
Materials are in short supply and are expensive.
Traditional manufacturing processes have access to a wider variety of raw materials than 3D printing-based manufacturing processes. Circuit boards, for example, are still being developed using 3D printing with mixed materials and technology. The materials that can be used are still small, despite the fact that technology is a major process breakthrough. In addition, due to a lack of proper specifications for the mechanical properties of the materials used, the accuracy and reproducibility of products produced by 3D printing are hampered.
Item size limitations
3D printing is a cutting-edge technology that has the ability to change the way industrial production is done. Manufacturers can print almost any form with a variety of materials (polymers, metals, ceramics, sand, paper, and living tissue). The size of the items that can be printed, however, is currently restricted by 3D printers. Size restrictions apply to parts produced additively using the 3D printing process. The most affordable 3D printers on the market today are small enough to fit on a desktop and have similar designed chamber sizes.
Process management isn't uniform.
Due to uncontrollable process variables and material variations depending on system and manufacturer, the accuracy of each 3D printing process varies. Just a few monitoring techniques currently exist that follow clear requirements by correcting process inconsistencies in the best 3D Printing Solutions. Due to the limited data available for process control, developing comprehensive and accurate mathematical models using 3D printing is difficult, particularly in complex and sophisticated applications (such as aerospace, military/defense, and healthcare).
Opportunities
Possibility of enhancing production processes and supply chain management
3D printing has progressed from its initial uses in modelling and prototyping to the production of usable components. 3D printing, unlike conventional manufacturing methods, can help solve multiple problems (such as higher tooling costs) associated with traditional manufacturing processes used for rapid prototyping and short production runs, among others, because 3D printing removes the need for tooling. Traditional manufacturing can be less costly per unit made, but it has a high initial cost in the form of tooling, making low-volume manufacturing more expensive.
Challenges
Ensuring the standard of the commodity
Particularly in the aerospace and medical device industries, the best 3D Printing Solutions allows for highly customised designs and products. However, the material specifications for AM of functional products are restricted, limiting AM's ability to manufacture highly customised products. The 3D printing industry faces a challenge in ensuring the quality of end products, particularly when they are produced repeatedly on the same or different printing machines. The quality of goods, particularly in terms of precision and efficiency, is determined by a number of factors, including materials, printing technology, and the environment in the printer, particularly temperature and pressure; any changes in these factors would have an impact on the end product's quality. In the near future, however, technical advances in current Best 3D Printing Solutions technology and the development of new materials tailored to specific application needs are expected to address this product quality challenge.
Copyright infringement is a threat.
With the growing use of this technology and the expiration of patents, 3D printers are likely to become very popular. Companies have also begun uploading their files to websites for consumers to select their goods, with the products then being sent to the customers. Customers may expect a higher level of customization for the goods they buy as a result of increased use. Increased market acceptance can lead to an increase in 3D piracy, or customers' willingness to manufacture products themselves rather than purchasing them from suppliers. Some businesses have even begun to share 3D files on their websites, increasing the risk of piracy even higher. This could lead to unauthorised reproduction of copyright-protected designs, which is a major concern for industrial 3D Printing Solutions designers.
3D PRINTING MARKET, BY TECHNOLOGY
The 3D printers available in the market are based on different technologies such as stereolithography (SLA), fused deposition modeling (FDM), selective laser sintering (SLS), direct metal laser sintering (DMLS), polyjet/multijet printing (MJP), inkjet printing, electron beam melting (EBM), laser metal deposition (LMD), laminated object manufacturing (LOM), and digital light processing (DLP). DMLS, SLS, and FDM are the most widely used 3D printing technologies.
STEREOLITHOGRAPHY
HIGH-QUALITY SURFACE FINISH PROVIDED BY SLA MAKES IT IDEAL FOR CONCEPT MODELS, FORM AND FIT STUDIES, AND INVESTMENT CASTING PATTERNS
SLA is a laser-based 3D printing technology that uses UV laser to cure and solidify thin layers of a photo-reactive resin. In this technology, a UV laser beam is projected on the photopolymer resin held in a vat, which hardens where the laser is directed. On the completion of one layer, the vat drops, and the subsequent layer is similarly cured by the UV laser. This process continues until the creation of the desired model. SLA is ideal for concept models, form and fit studies, and investment casting patterns as the technology provides a high-quality surface finish.
SLA-based 3D printing is used in the creation of anatomical models, lightweight concept models, architectural models, urethane casting patterns, and large investment cast patterns, among others. 3D Systems (US), Form Labs (US), Autodesk (US), and 3D Ceram (France) are some of the major companies offering 3D printers based on the SLA technology and services related them.
FUSED DEPOSITION MODELLING
FDM IS CLEAN, SIMPLE-TO-USE, AND OFFICE-FRIENDLY 3D PRINTING TECHNOLOGY
FDM technology is also known as fused filament fabrication (FFF) and plastic jet printing (PJP), is used to create concept models, functional parts, and end-use parts. The FDM technology uses strong, stable, and durable thermoplastic materials in filament form. The technology involves the layer-by-layer deposition of molten plastic material through an extruder onto the built platform; the model being built hardens after each newly added layer binds to the previous layer. Removable support material is deposited in the tray for organic shapes that require support. This support material can be removed easily through post-processing.
FDM is a clean, simple-to-use, and office-friendly 3D printing technology. It supports production-grade thermoplastics, which are mechanically and environmentally stable, and the technology is used to develop complex geometries and cavities. The applications of the FDM technology include manufacturing aids, jigs and fixtures, carbon fiber lay-up tooling, functional prototypes, and low-volume production parts. Stratasys (US), Ultimaker (Netherlands), and Afinia 3D (US) are some of the leading companies providing FDM-based 3D printing systems and services.
SELECTIVE LASER SINTERING
SLS DOES NOT REQUIRE SUPPORT FOR MATERIALS—POWDER BED ITSELF ACTS AS SUPPORT
The SLS technology uses a laser beam to fuse powdered thermoplastics. Compared to the technologies such as SLA and FDM, SLS does not require support for materials as the powder bed itself acts as a support. SLS is an affordable 3D printing technology that can be used to build durable and stable production parts in low volumes. The SLS-based 3D printers are also effective in producing high-volume components, which are too complex to build via a traditional manufacturing process. SLS has the ability to produce complex features, undercuts, and internal features, such as screw threads and threading tapped holes, with ease; moreover, these all can be produced in a single-step process. The printers based on SLS are capable of producing movable parts and parts with joints, snap fits, and living hinges. SLS-based 3D printing is deployed in the aerospace & defense, electronics, and automotive industries as well as in the healthcare, energy, and engineering sectors.
DIRECT METAL LASER SINTERING
USE OF MATERIALS SUCH AS INCONEL, ALUMINUM, STAINLESS STEEL, AND TITANIUM MAKES PARTS DEVELOPED FROM DMLS DURABLE
The printing process of the DMLS-based 3D printers is similar to that of the SLS-based 3D printers. The difference lies in the materials used in these printing technologies; DMLS is used for building metallic entities, while SLS is used for the printing of plastic-based entities. The parts developed from DMLS are durable and resistant to heat as it uses materials such as Inconel, aluminum, stainless steel, and titanium. The DMLS-based 3D printing process is ideal for developing complex oil and gas components, custom medical guides, consolidated aerospace parts, and tough functional prototypes owing to its ability to provide fine feature details.
POLYJET PRINTING/MULTIJET PRINTING
MJP IS USED TO DEVELOP HIGHLY ACCURATE MODELS WITH INTRICATE DETAILS AND COMPLEX GEOMETRIES
The PolyJet/MultiJet Printing (MJP) technology is an inkjet 3D printing method that is used to develop highly accurate models with intricate details and complex geometries. In PolyJet 3D printing, a layer of liquid photopolymer is deposited onto a build tray; the deposition is then cured by UV light to create a solid plastic-like material. The layers of UV-cured photopolymers accumulate on a build tray to create a 3D model. The printer also jets a gel-like support material to support the complex structures. A PolyJet 3D printer has 2 or more jetting heads. This technology is used by designers and engineers to develop and demonstrate final products with a smooth surface finishing. The printers based on this technology are used to develop presentation models; form and fit models; medical device prototypes; master patterns; flexible, rubber-like models; and prototypes for fittings, valves, and parts with complex interior features. Stratasys (US) and 3D Systems (US) are the leading companies in the 3D printing market that provide printing solutions based on the PolyJet technology. HP launched the multijet fusion technology 3D printer line in 2016 for small- to medium-sized businesses.
INKJET PRINTING
INKJET PRINTING ENABLES BUILDING OF MULT IPLE DIFFERENT PARTS ON SINGLE PRINT BED
Inkjet 3D printing technology, also known as binder jetting technology, involves the selective deposition of a liquid binding agent to join the powder particles, and the layers of powder material are bonded to form an object. Inkjet printing does not employ heat in the printing process, unlike other technologies wherein heat can create residual stress in the parts. Inkjet printing enables the building of multiple different parts on a single print bed. This technology is used in the development of castings, filtration, pumps, and prosthetics. It is used in the fields of aerospace, automotive, decorative/art, education, energy, foundries and pattern shops, heavy equipment, and research and development labs.
ELECTRON BEAM MELTING
PRINTERS BASED ON EBM TECHNOLOGY PRODUCE HIGH-DENSITY PARTS AND HAVE RELAT IVELY GOOD MECHANICAL PROPERTIES
In EBM, the 3D printing process takes place in vacuum and high-temperature conditions, and an electron beam selectively melts down the metal powder. The printers based on the EBM technology produce high-density parts and have relatively good mechanical properties such as low fatigue and high yield strength compared to traditional manufacturing technologies. EBM works with a limited number of materials and is an expensive 3D printing technology. The products developed using EBM include small series parts, prototypes for form/fit and functional testing, and support parts such as jigs and fixtures. EBM is used in industries such as aerospace, automotive, and healthcare.
LASER METAL DEPOSITION
LMD PRINTERS HELP REDUCE MATERIAL WASTAGE AND LOWER TOOLING COSTS
LMD involves the use of a laser beam, which is used to form a melt pool on the surface of existing tools and components, over which one or more metal powders are sprayed through a nozzle. The powder then melts and bonds with the base material. A computer numerical control (CNC) robot or gantry system is used to guide the laser and nozzle that delivers the powder. LMD 3D printing technology 3D printers benefit by reducing the material waste, lowering the tooling costs, repairing the parts that are costly to replace, minimizing the lead time, and customizing the parts according to the requirement. The LMD technology involves the repair, cladding, and production of parts. Some of the common applications of the printers based on this technology include repairing mold tool surfaces and high-value parts such as aeroengine components as well as military vehicles; tipping turbine blades with protective coatings; and surfacing oil and gas drilling components. LPW Technology (UK), Trumpf (Germany), Norsk Titanium (Norway), and DM3D Technology (US) are the major companies offering 3D printers, and printing services and solutions based on LMD. In November 2015, Toshiba (Japan) showcased its LMD-based metal 3D printer, whose fabrication speed is claimed to be 10-times faster than that of powder bed fusion printers.
DIGITAL LIGHT PROCESSING
DLP-BASED 3D PRINTERS PRODUCE ACCURATE PARTS WITH SMOOTH SURFACE FINISHING
DLP 3D printing technology is similar to SLA as both the technologies use photopolymers as materials. However, DLP uses convenient light sources such as digital micromirror device, while SLA uses laser. DLP 3D printing technology produces accurate parts with smooth surface finishing. Compared to SLA, DLP requires a shallow vat of resin, which results in less material wastage and lower running cost. The applications of DLP-based 3D printing include rapid fit and function model prototyping, tooling and metal casting mold manufacturing, hearing aids and medical implant manufacturing, dental restoration, jewelry casting, automotive component manufacturing, and aerospace component manufacturing.
LAMINATED OBJECT MANUFACTURING
LOM IS IDEAL FOR DEVELOPING PROTOTYPES, MODELS, AND MOLDS
The LOM-based 3D printers implement the sheet lamination process, which generally involves paper as the printing material and adhesives for binding the sheets. In this technology, the material is rolled on the building platform and coated with an adhesive layer, which is then heated by a heat roller to melt the adhesive so that the layers are bound to one another. The technology uses a blade or a laser to draw the geometry of the object which can be extracted as the final object. Cubic Technologies (US) is a major player in the 3D printing market offering printers enabled with LOM. This technology is ideal for developing prototypes, models, and molds.
OTHERS TECHNOLOGIES
OTHER TECHNOLOGIES INCLUDE CONTINUOUS LIQUID INTERFACE PRODUCTION, SELECTIVE HEAT SINTERING, NANOPARTICLE JETTING, AND MULTIPHASE JET SOLIDIFICATION
