The Ultimate Guide to 3D Print Supplies: Everything You Need to Get Started

So, you’ve taken the plunge into the fascinating world of 3D printing—congratulations! It doesn’t matter if you’re a hobbyist looking to print cool gadgets or a professional creating prototypes, having the right 3D print supplies is essential for success.

Today, we’ll walk through everything from essential filaments to must-have tools, helping you set up your perfect 3D printing workspace.

Filaments: The Heart of 3D Printing

Before you can start printing amazing objects, you need filament—the material your printer uses to create models layer by layer. The type of filament you choose affects everything from durability to flexibility and even how easy it is to print.

One of the most popular filaments for beginners is PLA (Polylactic Acid). It’s easy to print with, doesn’t require a heated bed, and comes in tons of colors. If you’re making decorative objects or prototypes, PLA is a fantastic choice. However, if you need something stronger, ABS (Acrylonitrile Butadiene Styrene) is worth considering. It’s more heat-resistant and durable but does require a heated bed and good ventilation since it emits fumes when printing.

For those wanting flexible prints, TPU (Thermoplastic Polyurethane) is a game-changer. It allows you to create rubber-like objects, making it perfect for phone cases, gaskets, or even wearable items. And if you’re looking for something truly tough, PETG (Polyethylene Terephthalate Glycol) offers the best of both worlds—strength like ABS but easier to print, like PLA.

Feeling experimental? Specialty filaments like wood, metal, or even glow-in-the-dark PLA add unique textures and finishes to your prints. Whatever your project, there’s a filament that fits!

The Right Bed Surface Makes a Difference

Now that you have your filament, let’s talk about print beds—the surface where your object is printed. A good print bed ensures that your prints stick well during the process but are also easy to remove afterwards.

Many printers come with a basic glass bed, which provides a smooth and flat surface, great for getting that shiny bottom layer. If adhesion is an issue, adding a PEI (Polyetherimide) sheet can work wonders. PEI is fantastic for keeping prints in place without needing extra adhesives like glue or tape.

Some printers use a magnetic flexible bed, which makes removing prints as easy as bending the sheet. And if you’re struggling with warping issues, a heated bed is a lifesaver—especially when working with ABS or PETG.

To boost adhesion further, materials like blue painter’s tape, Kapton tape, or glue sticks can provide that extra grip. The right print bed setup can mean the difference between a successful print and a failed one!

Essential 3D Printing Tools You Should Have

Having the right 3D print supplies goes beyond just filament and a printer. A few key tools will make your printing experience much smoother.

First, a spatula or print removal tool is a must-have for getting prints off the bed without damaging them. A pair of precision tweezers is also handy for clearing out small filament strings or fixing tiny details.

If you ever find that your nozzle is clogged (which happens more often than you’d think), a set of nozzle-cleaning needles will save the day. Keeping a soft brush and microfiber cloth nearby helps keep your printer dust-free and running smoothly.

For post-processing, sandpaper and a deburring tool help smooth out rough edges, while a soldering iron or heat gun can clean up stringy bits. If you want professional-level finishing, try acetone vapor smoothing for ABS prints—it gives them a glossy, injection-molded look.

And let’s not forget the most important tool: calipers! Accurate measurements ensure your designs fit together perfectly, whether you’re printing functional parts or just fine-tuning settings.

Keeping Your Filament Dry: Why Storage Matters

Filament might not seem like something that needs special storage, but trust me—moisture is the enemy. Many filaments, especially PLA, PETG, and Nylon, absorb moisture from the air, which can cause brittle prints, bubbles, and poor adhesion.

The best way to store filament is in an airtight container with silica gel packets to absorb any excess humidity. Some people even use vacuum-sealed bags or dry boxes with humidity sensors to keep filaments in perfect condition. If you suspect your filament has absorbed moisture, you can revive it by drying it in a food dehydrator or in your oven at a low temperature.

Keeping your filament dry ensures smoother, more reliable prints every time.

Choosing the Right Nozzle for the Job
Most 3D printers come with a standard 0.4mm brass nozzle, which works well for general printing. However, swapping out your nozzle for different sizes and materials can make a big difference in print quality and speed.

A larger nozzle, like 0.6mm or 0.8mm, can print stronger parts faster, making it great for functional models. If you need fine details, a 0.2mm nozzle is perfect for intricate prints, though it takes longer.

For filaments like carbon fiber, metal, or glow-in-the-dark PLA, a hardened steel nozzle is a must. These abrasive materials wear down standard brass nozzles quickly, so upgrading prevents frequent replacements.

Safety First: Precautions for a Smooth Printing Experience

3D printing is fun, but staying safe is important, too! If you’re using resin printers, always wear gloves and a mask, as uncured resin can be harmful. For filament-based printers, make sure your workspace is well-ventilated, especially when printing ABS, which can release fumes.

It’s also a good idea to have a fire extinguisher nearby—just in case. While 3D printers are generally safe, electrical components and heated beds mean it’s always smart to take precautions. And finally, never leave your printer running unattended for long periods!
