3D Printing Technology

The process of building a three-dimensional object or structure from a CAD model or digital 3D model is known as additive manufacturing, or 3D printing. The term “3D printing” is an umbrella term that covers a wide range of 3D printing processes and technologies. The following list includes some of the most popular 3D printing technologies.

Fused Deposition Modeling (FDM)

The most widely used 3D printing method, fused deposition modeling (FDM), is very useful for building plastic models, prototypes, and buildings. With production-grade thermoplastics, 3D items can be seamlessly constructed using this FDM technology. By melting a thermoplastic filament and layer-by-layer extruding the molten plastic, 3D objects are constructed. Complex structures can be made using specialized methods.

For instance, the printer may extrude a second substance that would act as support for the object being created during the printing procedure1. Later, the support material might be eliminated or dissolved.
Applications:
  • Functional prototypes
  • Concept models
  • Tools, jigs, and fixtures
  • Prosthetics
  • Pre-surgical models
  • Customized domestic products
  • Props & cosplay items

Stereolithography (SLA)

Stereolithography technology is one of the fast-prototyping printing methods that is best suited for printing intricate and precise details. In a matter of hours, the printer creates the 3D objects using an ultraviolet laser. An object is created using SLA technology by selectively curing a polymer resin layer by layer with an ultraviolet (UV) laser beam.
Applications:
  • Concept-based prototypes
  • Dental models
  • Investment casting patterns
  • Rapid tooling, jigs & fixtures
  • Designer models
  • Snap-fit assemblies
  • Exhibition or display models
  • Transparent coverings
  • Molds and casting patterns

Selective Laser Sintering (SLS)

In the SLS process, small powder particles are fused together by a powerful laser to form a mass with the desired three-dimensional shape. By initially scanning the layers or cross-sections on the surface of a powder bed, the laser selectively fuses powder. In order to build up the object to be made, a layer of powdered material is applied using a roller to the top of the layer beneath it. The powdered material is then laser sintered in accordance with a predetermined pattern. Due to the properties produced, selective laser sintering (SLS) is frequently used for the production of polymer parts.
Applications:
  • Functional prototypes
  • Investment casting patterns
  • Wind tunnel models
  • Rapid manufacturing of tooling, jigs, and fixtures.
  • Mockups of existing products
  • Medical device prototyping
  • Prosthetics and orthotics
  • Production of replacement spare parts,
  • Custom automotive hardware

Multi Jet Fusion (MJF)

A quick method of creating prototypes and finished products by employing the process of 3D printing is called Multi Jet Fusion (MJF). MJF provides engineering-grade materials with excellent all-around characteristics. In addition, MJF offers a better surface polish, finer details, more consistent mechanical qualities, and quicker manufacturing times. Final products made using MJF have higher-quality surface finishes, finer feature resolution, and more reliable mechanical properties than those made using processes like selective laser sintering.
Applications:
  • Functional nylon prototypes
  • End-use production parts
  • Spares with high quality surface finishes
  • Customized dental molds
  • Customizable medical prosthetics

Polyjet Printing

A sophisticated 3D printing method that incorporates the benefits of both plastic and powder-based techniques is called polyjet technology. Additionally, it provides the best single print combination of strength, efficiency, dependability, quality, and flexibility. If you want to offer your prototype a competitive edge in terms of design, materials, and accuracy, polyjet is the method to go with.
Applications:
  • Concept modeling
  • Rapid prototyping
  • Prototyping for complex parts
  • Preclinical testing parts
  • Replicas of human organs
  • Prosthetic limbs
  • Flexible, rubber-like models
  • Zero slip or soft surfaces

Multi-Jet Modeling (MJM)

Multi-Jet Modeling (MJM), also referred to as additive manufacturing or 3D printing, uses multiple layers of photopolymer that are stacked on top of one another and then UV-cured. The creation of things with a smooth surface and fine details is achievable thanks to multi-jet modeling.
Applications:
  • High-detail and intricate parts
  • Filigreed concept-based models
  • Design prototypes
  • High-end model making
  • Models with a delicate design
  • Models with thin walls
  • Precise mold and casting templates

Direct Metal Laser Sintering (DMLS)

DMLS is essentially very much like SLS, but it makes use of metal powder. The entire amount of powder that hasn’t been consumed becomes the object’s support structure. The next print can be made with leftover powder. The DMLS process is frequently used to create parts that have good surface finishes, outstanding physical qualities, and are frequently stronger than the standard metal itself. They can be employed with ceramics and metal super alloys, which are challenging to work with in conventional ways.
Applications:
  • Prototyping of production-grade materials
  • Functional prototypes
  • End-use parts
  • Waveguides
  • Custom Implants
  • Die and Mold Inserts

3D Printing Materials

Like the objects created by the 3D printing process, the materials utilized in 3D printing are highly diverse in nature. Some of the most commonly used materials for 3D printing are plastic and metals.

Plastic

Plastic is the most widely used raw material out of all the substances now used for 3D printing. It is used to create items like action figures, vases, and desk accessories. The appeal of plastic is simple to grasp given its firmness, flexibility, smoothness, and vibrant array of color options. Plastic is typically inexpensive, making it a good choice for both producers and consumers. Some of the widely used plastic materials in 3D printing are as follows.

How Does 3D Printing Work?

The techniques used in 3D printing are comparable to those of an inkjet printer and are a subset of the additive manufacturing process. With the 3D printing process, a three-dimensional object is built from scratch using a combination of cutting-edge software, powder-like materials, and precise instruments.
Model Designing:  By implementing 3D modeling, you can create a digital version of the item you wish to print. Later, the previously designed 3D model will be printed using the 3D printer. Object models are often created by utilizing a specialized computer program called a computer-aided design (CAD) package. In the modeling phase, manufacturing companies will check the model file for errors. Most CAD programs may locate errors that, if not fixed, could lead to problems in the printed product.

Slicing: Slicing is the process of using software to divide a 3D model into hundreds or thousands of layers. Your file is prepared for your 3D printer once it has been sliced. You can use USB, SD, or Wi-Fi to send the file to your printer, and your sliced file is now ready for layer-by-layer 3D printing.
3D Printing: Once the slice file has been created, you may upload it to the printer and calibrate it so that printing can begin. The appropriate file’s instructions will be used by the 3D printer to direct where and how the material should be placed. To increase printing accuracy, the extruders and the printing base need to be calibrated. You can watch the printing process while it is taking place through the printer’s transparent panel, or you can keep track of it remotely using our APP in real-time.
Finishing: Finishing is the fourth and last phase in 3D printing. Finishing, as the name implies, entails giving the printed piece its finishing touches. For example, solvents will be added to the 3D printed object to remove any surface flaws and produce a smoother surface finish. Alternatively, during this fourth and final phase, supports that were used to support the object during the printing process will need to be taken out.
