How to 3D Printing? The Definitive Beginner’s Guide

3d printing

In recent years, 3D printing has emerged as a revolutionary technology, transforming the way we design and manufacture objects. Also known as additive manufacturing, 3D printing allows you to create three-dimensional objects from digital models, opening up a world of possibilities for inventors, hobbyists, and professionals alike. Whether you’re a complete beginner or just curious about this technology, this comprehensive guide will take you on a journey through the fundamentals of 3D printing, providing you with the knowledge you need to get started.

Understanding the Basics of 3D Printing

3D printing, at its core, is a process of fabricating physical objects layer by layer. Unlike traditional manufacturing methods, which involve subtracting material through cutting or machining, 3D printing takes an additive approach, building objects from the ground up. The process begins with a digital model of the object, created using specialized computer-aided design (CAD) software or obtained from online repositories.

The digital model is then sliced into numerous thin layers using slicing software, which generates instructions known as G-code. These instructions guide the 3D printer on how to precisely deposit or cure material to form each layer of the object. The printer reads the G-code and executes the instructions, adding material layer by layer until the complete object is formed.

Types of 3D Printing Technologies

There are several different 3D printing technologies available today, each with its own strengths, limitations, and applications. Here are some of the most commonly used technologies:

  • Fused Deposition Modeling (FDM): This technology uses a thermoplastic filament that is melted and extruded through a nozzle. The nozzle moves in a predetermined pattern, depositing the melted material layer by layer to form the object. This usually include the cheaper machine on the market. And i suggest to start with them, giving you time to practice without break the bank. I actually tried a lot of these machines, and i suggest you to start with Ender 3 V2 Neo, a great printer all in one, ready to print without headaches.
  • Stereolithography (SLA): SLA utilizes a liquid resin that is cured by a UV laser. The laser selectively solidifies the resin, tracing the shape of each layer until the entire object is created.
  • Selective Laser Sintering (SLS): SLS involves the use of a high-powered laser that selectively fuses powdered materials, such as plastics, metals, or ceramics, layer by layer to create the object.
  • Digital Light Processing (DLP): Similar to SLA, DLP uses a liquid resin that is cured by a digital light projector, which projects an entire layer at once, solidifying the resin and forming the object.

Each technology has its own advantages and is suitable for different applications, such as FDM being widely used for rapid prototyping and hobbyist applications, while SLS is preferred for industrial-grade and high-precision parts.

Applications and Benefits of 3D Printing

3D printing has vast applications across various industries and fields. Some notable applications include:

  • Rapid Prototyping: 3D printing enables the quick and cost-effective production of prototypes, allowing designers to iterate and test their concepts before committing to large-scale manufacturing.
  • Customized Manufacturing: The ability to easily modify digital designs allows for the customization of products according to individual needs, whether it be personalized consumer goods or patient-specific medical devices.
  • Medical Applications: 3D printing has revolutionized the medical field, enabling the creation of patient-specific implants, prosthetics, anatomical models for surgical planning, and even human tissue and organs.
  • Aerospace and Automotive Industries: 3D printing is used in the production of lightweight and complex parts, reducing weight and improving fuel efficiency in aerospace and automotive applications.
  • Education and Research: 3D printing has become a valuable tool in educational institutions, enabling students to learn about design, engineering, and manufacturing processes through hands-on experience.

The benefits of 3D printing are numerous. It offers design freedom, allowing the creation of intricate and complex geometries that are challenging or impossible to produce using traditional methods. It reduces material waste, as only the required amount of material is used during the printing process. 3D printing also enables the production of on-demand and localized manufacturing, reducing inventory and transportation costs. Additionally, the technology has the potential to democratize manufacturing, empowering individuals and small businesses to bring their ideas to life without the need for extensive infrastructure.


3D printing has the potential to revolutionise various industries, from manufacturing and healthcare to art and education. As a beginner, embracing this technology opens up a world of creativity and innovation. By understanding the fundamental concepts, choosing the right equipment, and developing your design skills, you can unlock the full potential of 3D printing.

Remember, 3D printing is a constantly evolving field, and staying up to date with the latest advancements will help you stay ahead. So, embrace the possibilities, experiment, and share your creations with the world. With the knowledge gained from this beginner’s guide, you’re ready to embark on your exciting journey into the realm of 3D printing. Happy printing!
