3D printing has now become very influential at the present time, and although this technology has been around for many years, it was very expensive, and then 3D printers were gradually developed to become an option for ordinary consumers, so 3D printing technology is the most popular in the field of creative innovations, and through the Rakeen store we will learn more information about 3D printing technologies.
Types of 3D printing technologies
Binder jetting
This type of 3D printing is characterized by low cost with large production quantities and takes a short time in the production process, in addition to the flexibility in reproducing colors while maintaining the accuracy of 0.2 mm, but this technology is limited to low-density applications.
The input here depends mainly on the form of a powder deposited by the printer, forming a thin layer, where it is
Relying on a synthetic bonding agent, which bonds different layers of the part in a binder jet, the 3D printing process also works with a variety of materials, including polymers, sand, metal powders, and ceramic metal composites.
Applications on Binder Jetting:-
- Realistic models.
- Metal parts.
- Sand casting molds.
- Low cost prototypes.
material extrusion
It is an industrial process that pushes materials through a small nozzle to melt them. The extrusion process uses composite filaments and plastics such as ABS, PLA, PET, and other materials.
During this process, the material is deposited on a pre-determined path where it forms a layer, and then this process is repeated until the part is complete. The material extrusion technology is characterized by low cost with variety and accuracy, so it is the most common and widely used.
Applications of extrusion materials in 3D printing:-
- Shape composition.
- Investment casting patterns.
- Electronic boxes.
- Combinations.
blowing material
In this technique, the 3D printer uses dots or drops of liquid material to build each layer.
This process is characterized by the ability to use several different types of materials on one object, so it is easy to manufacture parts with homogeneous colors and textures that give you an idea of the final shape of the product, so the material jetting process is distinctive and unique.
Photopolymer resin is the only material capable of implementing this type of 3D printing process, but it is incompatible with any mechanical applications due to its brittle properties.
Applications on the material jetting process:-
- Develop medical models.
- Injection mold models.
- Aesthetic models.
- Design offers.
fusion powder
Here, a heat source is focused on a small area to melt the powder layer and penetrate between the layers of materials in the form of a powder. This process is carried out on most thermoplastics, metals and ceramics, to be able to provide an exceptional dimensional accuracy of 0.3%.
The most common applications based on powder bed fusion technology:-
- Hollow designs.
- Functional metal parts.
- Small batch production.
Container polymerization
This method provides an exceptional, unparalleled surface finish and allows you to create precise and complex geometries.
Here, a light source is used to cure the photopolymer resin. Photopolymer resin is the only material suitable for this, and it is available in many shapes and colors.
The main elements that distinguish the basin polymerization technique:-
- Digital Light Processing DLP.
- Stereolithography SLA.
- Masked Stereolithography MSLA.
This technology is widely used and the reason for the difference between many shapes is the light source, which plays a fundamental role in the processing process.
The most commonly used applications for 3D printing for container polymerization are:-
- Accessories and jewelry industry.
- Injection molds.
- Polymer models.
- Design offers.
- Dental implants.
- Medical parts.
direct energy deposition
Here, this technology relies on a powerful laser, electron beam, or plasma to activate and heat the materials to a high degree near the melting point in order to build the layers. This technology is not limited to construction only, but also repairs it.
This technology works simultaneously to push, deposit and cure layers and does not require any supporting structure.
The most common procedures are EBAM, LENS, and Cold Spray.
Applications of direct energy deposition technology:-
- Functional models.
- Repair of modern and advanced components.
Lamination plate
It's called this because of what it does, the technique involves stacking very thin metal sheets on top of each other to produce a three-dimensional object. Although this process is time-consuming and cost-effective, it is not precise and therefore offers limited avenues for functional applications.
The most common techniques are ultrasonic fusion (UC) and laminated object manufacturing (LOM).
The most common and widespread applications of panel lamination technology:-
- Design feasibility assessment.
- Display models.
- Non-functional models.
- Casting molds.
- Multi-color prints.
Factors that enable you to compare the above-mentioned technologies:-
- The strengths of the technology over other technologies.
- Production speed.
- Accuracy and quality.
- Weaknesses of this technology.

- Safety.
- Partial quantities.
The impact of 3D printing
3D printing technology achieves many advantages and benefits, whether at the local, industrial or personal level, that traditional, ordinary methods cannot achieve, such as:
Complexity
This technology allows you to do levels of complexity that are virtually impossible to produce with other methods, and the products are stronger and lighter.
Customization
3D printing technology allows customization according to individual requirements and desires, which enables you to manufacture several types of products in the same time without resorting to any additional cost.
Sustainability
3D printing technology reduces waste, is up to 90% more energy efficient than standard materials, and extends the product's lifespan, making it stronger and lighter.
3D printed products also have a lower carbon footprint than products manufactured using traditional methods.
Less tools
3D printing technology can reduce tooling usage, especially in low- to medium-volume manufacturing, resulting in lower costs, reduced time and labor, and avoiding assembly processes and associated costs and labor.
