What is 3D printing

What is 3D printing?

As one of methods of product manufacturing, 3D printing belongs to additive manufacturing, also known as three-dimensional printing/xyz printing, or layered manufacturing, which can be expressed as the process of printing and forming any three-dimensional objects.

3D printing requires a series of processes in which materials are stacked and formed into desired shape on a specific device according to pre-programmed model software to control 3D printer tools such as laser emitters or material nozzles.

3D printing types

So far, the most common 3D printing types can be classfied into following:

Fused Deposition Modeling (FDM)
Stereolithography (SLA)
Digital Light Process (DLP)
Masked Stereolithography(MSLA)
Selective Laser Sintering (SLS)
Multi Jet Fusion (MJF)
Direct Metal Laser Sintering (DMLS)
Electron Beam Melting (EBM)
Fused Deposition Modeling (FDM)

FDM printing

Fused Deposition Modeling (FDM) is also called fused filament fabrication (FFF), its principle is 3D object forming by material extrusion with a heated nozzle. The materials are deposited and formed into certain shape on a platform as a preset path in software.

FDM printing technology can print different materials, such as plastic, concrete, food, biogels, metal paste and other materials. But plastic is most common application material in FDM printing, in which includes plastic filament such as PLA, ABS, PET, PETG, TPU, Nylon, ASA, PC, HIPS, Carbon Fiber,etc.

Stereolithography (SLA)


Stereolithography (SLA), also known as photolithography, light-curing three-dimensional modeling, is a 3D printing technology used to create models, prototypes, patterns, etc. It uses the photopolymerization method to link small molecules to form polymers by light irradiation. These polymers form a solidified three-dimensional 3D object.

An SLA printer adopts mirrors that known as galvanometers or galvos, with one positioned on the X-axis and another on the Y-axis. These galvos rapidly aim a laser beam across a vat of resin, selectively curing and solidifying a cross-section of the object inside this building area, building it up layer by layer.Most SLA printers use a solid-state laser to cure parts. SLA printing needs common material is photopolymer resins.   SLA printing dimensional accuracy can be upto   ±0.5%, so comparing to traditional injection molding manufacturing, its strength is castable,transparent, biocompatable, fast and has a wide application in jewelry casting,dental,prototyping, games models, and others industrial applications.

Digital Light Process (DLP)

As one of   three common forms of vat polymerization(SLA, MSLA and DLP), digital light processing (DLP) uses a digital light projector to flash a single image of each layer all at once (or multiple flashes for larger parts).

Just like SLA counterparts, DLP 3D printers are built around a resin tank with transparent bottom and a build platform that descends into a resin tank to create parts upside down, layer by layer.The light is reflected on a digital micromirror device, a dynamic mask consisting of microscopic-size mirrors laid out in a matrix on a semiconductor chip. Rapidly toggling these tiny mirrors between lens(es) that direct the light towards the bottom of the tank or a heat sink defines the coordinates where the liquid resin cures within the given layer.

Masked Stereolithography(MSLA)


Masked Stereolithography (MSLA) uses an LED array as its light source, shining UV light through an LCD screen displaying a single layer slice as a mask — hence the name.Like DLP, the LCD photomask is digitally displayed and composed of square pixels. The pixel size of the LCD photomask defines the granularity of a print. Thus, the XY accuracy is fixed and does not depend on how well you can zoom/scale the lens, as is the case with DLP. Another difference between DLP-based printers and MSLA technology is that the latter utilizes an array of hundreds of individual emitters rather than a single-point emitter light source like a laser diode or DLP bulb.

Similar to DLP, MSLA can, under certain conditions, achieve faster print times compared to SLA. That’s because an entire layer is exposed at once rather than tracing the cross-sectional area with the point of a laser.Due to the low cost of LCD units, MSLA has become the go-to technology for the budget desktop resin printer segment.

Selective Laser Sintering (SLS)

FDM printing
Selective laser sintering   (SLS) is an additive manufacturing technique that uses a laser as a power source to sinter powdered materials, automatically aiming the laser at a point in a space defined by a 3D model, bonding the materials together to form a strong structure. It is similar to selective laser melting; both are instances of the same concept, but differ in technical details. SLS is a relatively new technology, and so far it has mostly been used for rapid prototyping and low-volume production of parts.

SLS printing involves the use of a high power laser (for instance,a carbon dioxide laser) to fuse small particles of metal, ceramic, or glass powders into a mass that has a desired three-dimensional shape. The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part (for example from a CAD file or scan data) on the surface of a powder bed. After each cross-section is scanned, the powder bed is lowered by one layer thickness, a new layer of material is applied on top, and the process is repeated until the part is completed.

Multi Jet Fusion (MJF)

FDM printing
Multi Jet Fusion (MJF) is a 3D printing process that speedily produces accurate and finely detailed complex parts with powdered thermoplastics. Using an inkjet array, MJF works by depositing fusing and detailing agents in a bed of powder material, then fusing them into a solid layer. The printer distributes more powder on top of the bed, and the process repeats layer by layer.

Multi Jet Fusion uses a fine-grained materials that allows for ultra-thin layers of 80 microns. This leads to parts with high density and low porosity, compared to parts produced with Laser Sintering. It also leads to an exceptionally smooth surface straight out of the printer, and functional parts need minimal post-production finishing. That means short lead times, ideal for functional prototypes and small series of end-parts.For industrial applications. It’s commonly used to manufacture functional prototypes and end-use parts, parts that need consistent isotropic mechanical properties, and geometries that are organic and complex.


FDM printing
PolyJet printing is an industrial 3D printing process that builds multi-material prototypes with flexible features and complex parts with intricate geometries in as fast as 1 day. A range of hardnesses (durometers) are available, which work well for components with elastomeric features like gaskets, seals, and housings.

The PolyJet process begins by spraying small droplets of liquid photopolymers in layers that are instantly UV cured. Voxels (three-dimensional pixels) are strategically placed during the build, which allow for the combination of both flexible and rigid photopolymers know as digital materials. Each voxel has a vertical thickness equal to the layer thickness of 30 microns. The fine layers of digital materials accumulate on the build platform to create accurate 3D-printed parts.

Direct Metal Laser Sintering (DMLS)

FDM printing
Direct Metal Laser Sintering (DMLS) is a direct metal laser melting (DMLM) or laser powder bed fusion (LPBF) technology that accurately forms complex geometries not possible with other metal manufacturing methods.

DMLS uses a precise, high-wattage laser to micro-weld powdered metals and alloys to form fully functional metal components from your CAD model.DMLS parts are made with powdered materials like aluminum, stainless steel and titanium, as well as niche alloys like MONEL® K500 and Nickel Alloy 718.

Electron Beam Melting (EBM)

FDM printing
EBM printing technology uses an electron beam produced by an electron gun. The latter extracts the electrons from a tungsten filament under vacuum and projects them in an accelerated way on the layer of metallic powder deposited on the building plate of the 3D printer. These electrons will then be able to selectively fuse the powder and thus produce the part.

EBM technology is mainly used in aeronautics and medical applications, particularly for implant design. Titanium alloys are particularly interesting because of their biocompatible properties and mechanical properties, they can offer lightness and strength. The technology is widely used to design turbine blades, for example, or engine parts. Electron Beam Melting technology will create parts faster than LPBF technology, but the process is less accurate and the finish will be of lower quality because the powder is more granular.

Benefits of 3D printing

Lower costs

Within the 3D printing sector, services offering CNC parts online mean you can upload your designs, get an instant quote and see your part being made almost immediately. This is a massive step forward from the complicated process of getting a product to market using traditional manufacturing, and significantly cheaper, too. Clearly this is of great benefit to businesses needing parts. But the applications compatible with 3D printing technology are growing on a daily basis—there are already people living in 3D printed houses. As development continues, more and more ordinary people will begin to reap the cost rewards of this huge growth industry.

Manufacturing flexibility

Using traditional manufacturing techniques, complicated designs were generally more difficult to produce. 3D printing has opened a pathway to the previously unimaginable for designers and entrepreneurs. With the ongoing addition of new printing materials, including metal and fabric, the scope for adapting 3D printing to multiple sectors is seemingly limitless. Already industries like automotive, energy and aerospace are plugging into the potential offered by this technology, and its presence is beginning to be felt across the industrial spectrum the world over.

Medical advances

The benefits 3D printing can bring to new medical developments is already well understood. Victims of accidents and diseases have received 3D printed bone implants, which can be created with absolute precision. These implants often mean that metal plates or fastenings do not have to be surgically removed when the bone has healed. Medicine is also becoming more patient-specific, as scans allow the creation of 3D models of affected areas. Treatment can be significantly influenced by such preoperative models, with surgery times substantially reduced. New developments in the field of medicine and 3D printing are emerging on an almost daily basis.


The streamlined processes of 3D printing are speeding up production schedules, and reduced manufacturing time in the long term means reduced energy consumption. Additive manufacturing also produces less waste than many processes, and when it comes to plastic, these technologies could become a key factor in the drive to clean up our oceans. Other benefits include online services like 3D printing Chicago, where production is brought closer to the customer, reducing pollution from heavy transport. With an Amsterdam project already using waste plastic to print street furniture, 3D printing is looking increasingly friendly for the environment.

Economic growth

3D printing has ushered in a new era of creative possibilities, and the ongoing development of innovative materials will see those possibilities grow. Ideas that were once impossible to realize are now within our grasp, and the world of design and manufacture has suddenly expanded to new horizons. Entrepreneurs are already harnessing the technology to create products we never knew we needed. Economies across the globe will benefit as fresh, groundbreaking businesses are born. Sooner than we think, we’ll be buying items that haven’t been invented yet, and wondering how we ever lived without them.

      Advantages of 3D printing prototypes


      1. With good complex manufacturing capability, it can complete manufacturing difficult to be completed by traditional methods. The product is complex, and only through multiple rounds of design – prototype machine production – test – modification design – prototype machine reproduction – re-test process, through the prototype machine repeated test can timely find problems and correction. However, the output of the prototype is very small, and it takes a long time and high cost to adopt the traditional manufacturing method, resulting in a long development cycle and high cost.


      2. Low cost and fast speed of small batch manufacturing can significantly reduce the development risk and shorten the development time. 3D printing ingot casting with planks do not need to traditional manufacturing mode, system, mold and die forging process, can rapid prototype production, low cost, and digital, the entire production process can be modified at any time, at any time, in a short time, a large number of verification test, thus significantly reduce the risk of developing, shorten the development time, reduce the development cost.


      3. High material utilization, can effectively reduce the production cost. The traditional manufacturing is “material reduction manufacturing”, through the raw material billet cutting, extrusion and other operations, remove the excess raw materials, processing the required parts shape, the processing process of the removal of raw materials difficult to recycle, the waste of raw materials. 3D printing only adds raw materials where it is needed, and the material utilization rate is very high, which can make full use of expensive raw materials and significantly reduce the cost.
