Getting Started with 3D Printer Filament: A Beginner’s Friendly Guide

Well, you have just had your first 3D printer or perhaps you are still researching before dipping your toe into the water? You may become lost in the world of 3D printer filament. Trust me, I know–infinite types, colors and specifications. However, the difference in your prints can all depend on the right filament, aspects of it such as look and feel, durability, and simply printing.

Choosing the improper 3D printer filament is the common pitfall that allows newcomers to reduce their success. It may cause the warpage, weak regions, or missing print that wastes time and material. This guide will deconstruct the most common filaments, including the most popular PLA 3D filament and tell you which material best meets different printing requirements. No head scratching, just simple information to help you print with no fuss.

The Basics: Most Popular 3D Printer Filament

PLA 3D Filament (Polylactic Acid)

PLA 3D filament is the safest bet, as you step into 3D printing. The reason why this type of plant-based plastic printing material is popular is its ease in printing, sustainability, and the final output which looks very good. I recall spooling my first roll of PLA 3D filament, which was surprisingly smooth even at lower temperatures (multiple times, 180- 220℃), and even my fixed-priced 3D printer was not burdened with this.

There is also a faint elegant sweet aroma to the PLA filament when printing which by far is much nicer than the intense chemicals that other material has when being printed. It produces fine prints of smooth surfaces, ideal in the case of models and prototypes. The caveat is that PLA does not do well with heat, so keeping PLA prints outside in the sun, or near other hot locations can result in warping.

ABS (Acrylonitrile Butadiene Styrene)

ABS is what Lego bricks are composed of so it is tough and durable. After going through PLA, I changed to ABS. By that time I needed stronger parts to withstand wear and tear. However, you will need to treat them with ABS in mind – it has a higher requirement on print temperatures (220-250℃) and to avoid warping it requires a heated bed.

That time I had issues with an unpleasant odor and warping when I first printed with ABS. Being in a closed up printer environment and proper ventilation really assisted. ABS is ideal on functional components that require power and warmth resistance once it is dialed into it.

PETG (Polyethylene Terephthalate Glycol)

Wanting to find the golden mean? PETG filament has the properties of ABS, which makes it strong with the printability characteristic of PLA almost. This type of 3D printer filament adheres readily to a print bed with parts that are both waterproof and shockproof, which is perfect in making outdoor parts or mechanical objects.

PETG is good with projects such as phone mounts and waterproof containers- can take the heat and weather. Printing temperatures are comparable to that of ABS (230-250℃) however PETG does not produce strong fumes making it a more pleasant item to print.

TPU (Thermoplastic Polyurethane)

Desire prints that are agile and rubber like? The experiment is TPU. It is ideal in phone cases, grips and shock absorbers because it is bendable and elastic. However, a friendly note, printing TPU takes some patience to print properly as it jams in some printers, mainly Bowden extruders.

Nevertheless, the peculiarities of TPU make it possible to create creative, flexible components that would not have been made with standard filaments.

Specialty 3D Printer Filaments to Explore

Nylon

Nylon filament is preferred where strong wear resistant items are necessary. When stressed it bends rather than breaks and hence, it is superb as a drone part or gears. Nevertheless, nylon is easily subject to moisture in the air and therefore should be stored properly and dried prior to printing.

Nylon cannot be considered entry-level because of high printing temperatures (240-260℃) and warping problems, but its properties of strength and flexibility are unrivaled.

Wood-Filled Filaments

Wood filled PLA 3D filament is a mix of standard PLA mixed with finely milled wood to provide you with prints that look and feel just like wood. Prints are larger than reality with a realistic feel and odour, they are even sandable or stainable as wood.

Only one thing to know: Wood filled filament will wear out your print nozzle more quickly so you should use a hardened steel nozzle should you be printing with it regularly.

FAQs About 3D Printer Filament

Can I alternate the type of 3D filament on my Printer?

Yes! Just be sure to clean the nozzle in between changes keeping it clear of clogs and mixing of colors.

Is there an impact on the print speed of filament choice?

Absolutely. Generally PLA 3d printing plastic will be faster than flexible filament such as TPU which requires slower speeds to avoid jams.

Which is the best filament outdoors?

PETG and certain nylon varieties hold on to their shape outdoors, even having a greater degree of resistance when it comes to UV wear than PLA.

Final Thoughts

Proper use of 3D printer filament may save you annoyance and material waste by beginning with suitable filament. If you are a new user, PLA 3D filament is the most versatile and least difficult to use- best on prototypes, decorative printing and simple projects. In case you require the more heat resistant, and more durable sections, ABS or PETG is going to be the way to go. And when it comes to flexible and unique prints there is amazing potential available in TPU.

Keep in mind that each printer acts slightly differently, gain some experience and talk to other amateur users in forums on the net. Record your settings of each brand and type of filament by filament so that you can create your own ideal printing recipes. After spending time working with 3D print filament, selecting the correct type of 3D print filament becomes second nature and your prints will be happier as a result.
