What is 3D Printing? A Beginner’s Guide to Additive Manufacturing

3D printing, also known as additive manufacturing, is a groundbreaking technology that enables users to create three-dimensional objects layer by layer from digital designs. Whether you're an entrepreneur, a hobbyist, or an educator, 3D printing empowers you to turn ideas into reality with precision and efficiency.

At ReddHill.com and our Niles RadioShack storefront, we specialize in providing high-quality 3D printing supplies, including Flashforge 3D printers and Polymaker filament. As official resellers of both brands, we’re not just recommending them—we genuinely believe in their quality and reliability. In this guide, we’ll explain the fundamentals of 3D printing and help you choose the best tools to get started.

How Does 3D Printing Work?

The 3D printing process begins with a digital 3D model, which can be created using CAD (Computer-Aided Design) software or downloaded from repositories like Thingiverse and Printables. The model is then prepared using slicing software like Orca, which is used for Flashforge 3D printers. Orca slices the model into layers and generates G-code, the instructions that tell the printer how to build the object.

Once the file is uploaded to the 3D printer, the printer constructs the object layer by layer using filament material, which solidifies into the final shape.

Key Components of 3D Printing

To successfully start 3D printing, you’ll need two essential components: a 3D printer and filament material.

1. 3D Printers: The Core of 3D Printing

A 3D printer is the device that brings digital models to life by extruding filament material into precise layers. As an official reseller of Flashforge, we confidently recommend Flashforge 3D printers for their reliability, ease of use, and high-quality prints.
