Stereolithography

SLA

Stereolithography (SLA) is the use of UV lasers to cure liquid resin layer by layer to create 3D objects. The technology produces highly detailed and precise parts and is ideal for applications such as rapid prototyping, product design, and dental and medical modeling.

Selective Laser Sintering

SLS

Selective Laser Sintering (SLS) is a 3D printing technology that uses a high-powered laser to fuse powdered material layer by layer to create a 3D object. This technology is ideal for creating complex geometries and functional parts with high strength and durability. 

Fused Deposition Modeling

FDM

Fused Deposition Modeling (FDM) is a 3D printing technology that involves depositing melted thermoplastic material layer by layer to create a 3D object. This technology is widely used for rapid prototyping, as well as for creating functional parts and models.

Materials for 3D Printing

Choosing the right materials is critical to creating custom prototypes and parts that meet the required mechanical properties, functions and appearance requirements. You can check out the basics of 3D printing materials at Longsheng in order to choose the right material for your final part.

polylactic acid

PLA

PLA, or Polylactic Acid, is known for its high stiffness, excellent detailing capabilities, and affordability. This biodegradable thermoplastic offers good physical properties, including notable tensile strength and ductility.

nylon

Nylon

Nylon, a versatile choice for 3D printing, stands out with its exceptional combination of properties. It boasts impressive impact resistance, making it suitable for applications that require durability and strength. This thermoplastic material is known for its toughness, with the ability to withstand significant mechanical stress.

ABS

ABS, short for Acrylonitrile Butadiene Styrene, is a widely-used thermoplastic known for its versatility and balanced properties.It possesses excellent impact strength, making it suitable for parts and prototypes that need to withstand physical stress and potential impacts. This robustness ensures that ABS-printed objects have a greater resistance to breaking or cracking.

 

Polypropylene

A key characteristic of polypropylene is its high impact resistance, which enables 3D printed parts to withstand physical stress and impact, and it also has good chemical resistance, ensuring that it can withstand exposure to various chemicals and solvents without degradation.

3D Printing Overview

What is 3D Printing?

3D printing, also called additive manufacturing, is a process of creating physical objects from digital models by adding material layer by layer. It’s used for rapid prototyping, customization, and making complex shapes in various industries.

 

What are the advantages of 3D printing?

This revolutionary technology, in stark contrast to traditional subtractive manufacturing methods like machining and casting, builds objects layer by layer from digital designs, unlocking a treasure trove of advantages that have reshaped the way we think about manufacturing.

– Iterative design and prototyping
– Cost-effective for low volume production
– No upfront tooling costs
– Complex Geometries

 

How 3D printing works step by step?

It starts with designing a 3D model on a computer, which serves as a blueprint for what you want to create. This model is divided into very thin horizontal layers using special software.

Next, a 3D printer prepares for action. It’s loaded with the material you want to use, which could be plastic, metal, resin, or even food. The printer reads the digital design and starts building the object layer by layer.

Each layer is like a super-thin slice of the final object. These layers are carefully placed on top of each other, and they stick together, eventually forming the complete 3D object.

Depending on the type of 3D printer, some layers may cool down and harden while others are being added. This process continues until the entire object is finished.

Once printing is complete, you may need to do some post-processing, like sanding or painting, to get the desired look and feel. Then, you’ve got your 3D-printed object, ready to be used for whatever purpose you had in mind!

Applications for 3D Printing

Here are some common 3D printing applications in various industries and examples of typical parts produced:
