Comparing Additive Methods: Exploring the World of FDM, SLA, SLS, and Polyjet in 3D Printing

-

 The additive methods of 3D printers are divided into FDM, SLA, SLS, and Polyjet, and each method has its own characteristics and advantages.


In this blog, we will go into detail about each method.


Fused Deposition Modeling (FDM)

FDM builds a model by melting filament material and building it up layer by layer.



After designing the desired model through 3D design software, the model is built by loading the filament material and adjusting the print settings.


FDM is inexpensive, easy to use, and has the advantage of using a wide range of materials.


SLA (Stereolithography)

SLA is a 3D printing technology that creates models through a light curing process.


It works by irradiating photocurable materials with laser or UV light to form layers.


SLA provides high resolution and detail and is widely used for precise prototyping, medical models, and jewelry making.


The surface of the model is smooth and finely detailed, resulting in realistic and sophisticated results.


SLS (Selective Laser Sintering)

SLS builds models by using a high-heat laser to solidify powdered material.



SLS can use a variety of materials and has the advantage of being able to produce complex models without the need for supports.


SLS is used in manufacturing, medical, and automotive industries, and is particularly useful for parts that require strength.


Parts made with SLS are extremely durable.



Polyjet

Polyjet is a 3D printing technology that forms layers by jetting material in a liquid state.


Polyjet is widely used in design and product development because it can work in a variety of colors and materials simultaneously, provides high-resolution output and a variety of material combinations.


Polyjet can create accurate, realistic models and help bring your creative ideas to life.


Each 3D printer additive method has its own characteristics and advantages, and is selected and used according to the appropriate application and needs.


This can enable more creative and efficient manufacturing and production in various industries.

  In recent years, 3D printing has emerged as a groundbreaking technology that is revolutionizing the manufacturing industry. With its ability to transform digital designs into physical objects, 3D printing has paved the way for a new era of model production. This blog post explores the significant impact of 3D printing on the manufacturing process and how it is reshaping the way models are produced.   1. The Power of Additive Manufacturing At the core of 3D printing lies the concept of additive manufacturing, which enables the creation of three-dimensional objects layer by layer. Unlike traditional subtractive manufacturing methods that involve cutting, shaping, and molding raw materials, additive manufacturing adds material in a precise and controlled manner. This approach allows for the production of complex geometries and intricate designs that were once considered challenging or impossible.   2. Enhanced Design Freedom One of the key advantages of 3D printing in model prod

3D printing technology offers an innovative manufacturing method that can be utilized for creating various industrial models. This technology revolutionizes the design and manufacturing processes, providing time and cost savings, as well as accuracy and flexibility. In this blog, we will guide you through the process of creating industrial models using 3D printing.   Design Phase The production of industrial models using 3D printing begins with the design phase. Computer-Aided Design (CAD) software allows you to create a 3D model. Consider all the necessary details and functionalities while designing the model.   File Preparation Once the design is complete, it needs to be converted into a file format suitable for 3D printing. The most commonly used format is STL (Stereolithography). STL files store the 3D model by breaking it down into small triangles.   Slicing A 3D printer recognizes and prints the 3D model layer by layer. To achieve this, slicing software is used to div

3D printing is an innovative technology that is being utilized in various industries. To create products using 3D printing, one needs to design models using modeling software. SketchUp is one of the software choices many people opt for when approaching 3D modeling. However, SketchUp may not be the optimal choice for 3D printing modeling tasks. In this blog post, we will explore the reasons why using SketchUp for 3D printing modeling is not ideal. 1. Limited functionality SketchUp was primarily developed as a tool for architecture and interior design, focusing on handling simple shapes and surfaces. As a result, it may have limitations when it comes to more complex modeling requirements necessary for 3D printing. Achieving high resolution and intricate modeling needs may be challenging with SketchUp. Therefore, using other software options can be more effective in meeting those demands. 2. File compatibility issues SketchUp utilizes a proprietary file format, which can limit its compati
