Best 3d Printer Accessories You Actually Need

So, you’ve just unboxed your shiny new 3D printer, or perhaps you’re a seasoned maker looking to refine your workflow. While the printer itself is the star of the show, a truly successful and enjoyable 3D printing experience relies heavily on having the right support cast: a collection of essential 3d printer accessories you need to ensure smooth operations, better print quality, and easier maintenance. Think of these as the unsung heroes that transform a good print into a great one, and a frustrating print session into a productive one. From keeping your filament in pristine condition to making post-processing a breeze, these accessories are worth their weight in perfectly printed plastic. And if you’re still looking for the perfect machine, don’t forget to check out our top recommended 3D printer picks.

Filament Storage & Management

Filament is the lifeblood of your 3D printer, and how you store it directly impacts print quality. Moisture is the enemy, leading to issues like stringing, blobbing, and brittle prints.

Dry Box or Dehydrator

A filament dry box or dehydrator is arguably one of the most crucial accessories, especially if you live in a humid environment or print with hygroscopic materials like PETG or Nylon. These enclosures maintain a low-humidity environment, keeping your filament spools dry and ready for action. Some even allow you to print directly from the dry box, ensuring consistent conditions throughout your print.

Desiccant Packs

For a more budget-friendly approach or as an addition to a dry box, desiccant packs (like silica gel) absorb moisture from the air. You can place them directly in sealed bags with your filament spools or within a storage container. Remember to reactivate or replace them periodically as they become saturated.

Build Plate Essentials

The first layer is arguably the most important. Good bed adhesion is non-negotiable for successful prints, and the right tools make removal simple.

Adhesion Aids

Depending on your build plate material and the filament you’re using, you might need a little extra help with adhesion. Common aids include:

• PVA Glue Sticks: Washable and effective for PLA on many surfaces.
• Hair Spray (unscented, extra hold): A popular choice for ABS and PETG, creating a sticky layer.
• PEI Sheets: A fantastic upgrade for many printers, offering excellent adhesion when hot and easy release when cool for a variety of filaments.

Print Removal Tools

Once your print is done, you need a safe way to remove it without damaging the print or your build plate. A good set of spatulas or a flexible print sheet can make all the difference. Magnetic flexible build plates, in particular, simplify removal immensely—just flex the plate and your print pops right off!

Cleaning Supplies: Isopropyl Alcohol (IPA)

A clean build plate is a happy build plate. Fingerprints, dust, and residual adhesion aids can all impede proper first layer adhesion. A bottle of 90%+ Isopropyl Alcohol (IPA) and some lint-free cloths are essential for regular cleaning between prints.

Tools for Maintenance & Post-Processing

3D printing isn’t just about pressing print; it’s also about preparing your models and maintaining your machine.

Pliers and Snips

A good pair of flush cutters (snips) is indispensable for trimming filament, removing supports, and cleaning up your prints. Needle-nose pliers can be useful for gripping small parts or retrieving filament fragments from tight spaces.

Calibration Tools

Achieving dimensional accuracy and perfect prints often requires careful calibration. A few tools can significantly aid this process:

• Digital Calipers: Essential for precise measurements of printed parts, filament diameter, and for calibrating extrusion.
• Feeler Gauges: Excellent for accurately setting the nozzle-to-bed gap during manual bed leveling, providing a more consistent and precise gap than paper.

Deburring Tool or X-Acto Knife

For cleaning up prints, especially removing stringing, elephant’s foot, or fine supports, a deburring tool or a sharp X-Acto knife (with various blades) is invaluable. These allow for precise trimming and smoothing, giving your prints a professional finish.

Nozzle Cleaning Kit

Clogged nozzles are an inevitable part of 3D printing. A nozzle cleaning kit typically includes thin needles (for clearing blockages) and brass brushes (for cleaning the outside of the nozzle). Prevention is key, but having these on hand will save you a lot of headaches.

Filament Variety & Experimentation

While not strictly “accessories” in the tool sense, having a diverse range of filaments on hand opens up new creative possibilities and makes you a more versatile maker.

High-Quality PLA

Always have a supply of reliable Hatchbox PLA (or Overture PLA) in common colors. It’s the most user-friendly filament and perfect for prototyping and general-purpose prints.

Specialty Filaments

Don’t be afraid to branch out! Materials like PETG filament offer greater strength and temperature resistance than PLA, making them suitable for functional parts. For flexible applications, TPU filament is a fantastic choice, allowing you to print bendable and impact-resistant objects.

Safety & Comfort

3D printing involves heat and sometimes fumes, so safety should always be a consideration.

Fume Hood or Enclosure

Printing with certain materials (like ABS or some resins) can produce ultrafine particles and VOCs. A well-ventilated enclosure or a dedicated fume hood can help mitigate these emissions, making your printing space safer and more comfortable.

Fire Safety

While rare, 3D printers do involve heating elements and electricity. Having a smoke detector in your printing area and a small fire extinguisher designed for electrical fires (Class C or ABC) provides peace of mind.

Quality of Life Upgrades

Some accessories simply make your printing life easier and more efficient.

Spare Nozzles (Various Sizes & Materials)

Having a selection of spare nozzles isn’t just for replacing worn ones; different nozzle sizes (e.g., 0.2mm for fine detail, 0.6mm for faster prints) can expand your printing capabilities. Consider hardened steel nozzles for abrasive filaments.

Auto-Leveling Sensor (if applicable)

If your printer doesn’t come with one, adding an auto-leveling sensor (like a BLTouch or CR-Touch) can be a critical tool. It eliminates the tedious manual bed leveling process, ensuring a perfect first layer almost every time.

Camera for Remote Monitoring

For longer prints or when you’re away from your printer, a simple webcam connected to a Raspberry Pi (running OctoPrint) or a dedicated smart camera allows you to monitor your print progress remotely, catch failures early, and even create timelapses.

Investing in these 3d printer accessories you need will not only improve the quality of your prints but also enhance your overall 3D printing journey. From crucial maintenance tools to smart upgrades, each item plays a role in making your creative process smoother and more enjoyable. Ready to stock up?
