5 Essential Things You Need to Get Started with 3D Printing

So you’re interested in diving into the world of 3D printing, but you’re not quite sure where to begin. Fear not! In this guide, we’ll break down the five essential things you need to get started with 3D printing. Whether you’re a complete beginner or just looking to expand your creative horizons, this article will equip you with the knowledge you need to embark on your 3D printing journey.

1. The Right 3D Printer

The very first thing you’ll need is a 3D printer. With a multitude of options on the market, choosing the perfect one for you can be a bit overwhelming. There are two primary types of 3D printers: filament-based and resin-based. Filament-based printers use plastic filaments on a reel, while resin-based printers utilize a liquid polymer exposed to UV light for solidification. For the purpose of this guide, we’ll focus on filament-based printers, which are more common and user-friendly.

Keep in mind that different printers offer varying print speeds and build sizes, so consider your preferences and priorities before making a choice.

2. A 3D Model to Print

Once you have your printer ready, you’ll need a 3D model to print. There are several ways to acquire models, especially when you’re just starting out. Online platforms like Thingiverse and Printables provide vast libraries of pre-designed 3D models that you can download and use for your projects. However, if you intend to sell the item, be sure to review the permissions granted by the model’s creator, as some may have restrictions on usage or require attribution.

Alternatively, you can create your own 3D models using Computer-Aided Design (CAD) software. These models should be exportable in formats like STL or 3MF for compatibility with 3D printer slicing software (see next section).

3. Slicer Software

To bring your 3D model to life, you’ll need slicer software. A slicer takes your 3D model and translates it into instructions that your printer can understand. It breaks down the model into slices and calculates the printer’s movements to replicate each slice, layer by layer. Popular slicers include Cura, Slic3r, and PrusaSlicer. Each slicer has unique options to help streamline and improve the printing process. Be sure to check out the features and select one that meets your requirements and is easy to use.

4. Filament – The Printing Material

Filament is the material used for 3D printing. For beginners, PLA (PolyLactic Acid) filament is often recommended due to its ease of use and impressive results. Keep in mind that PLA has temperature limitations and might not be suitable for high-temperature environments. While 3D-printed objects inherently have visible layer lines, PLA can be a bit tricky to finish since sanding can distort the model. However, smoothing agents like Smooth-On XTC-3D can help achieve a smoother finish.

5. Essential Tools

Lastly, having the right tools on hand can make your 3D printing experience more efficient and enjoyable. Necessary tools include:

  • Flush Cutters: These are invaluable for removing support material and trimming unwanted parts of your prints.
  • Scraper Tool: Used to carefully remove prints from the printer bed.

Nice-to-have tools include:

  • Deburring Tools: Useful for removing brims and addressing issues like “elephant’s foot” where the first layer gets squished.


Starting with 3D printing might seem daunting, but armed with these five essential components, you’ll be well on your way to creating your own unique 3D-printed creations. Remember that 3D printing is a diverse and exciting realm, so explore, experiment, and enjoy the process of bringing your ideas to life.
