The enclosed chamber covered in Monday’s article on the P series keeps a stable temperature inside the box and partially protects a mounted spool too, but it won’t remove moisture that has soaked deep into the filament’s structure on its own. That’s where a dryer comes in. Wet filament is one of the most...
Recycled Filament rPLA and rPETG: Saves Money and the Planet?
In Monday’s topic this week we looked at filament storage and its life cycle as a long game, where it pays to think about what you’ll be doing with the material years down the road; recycled filament is the logical next step in that line of thinking, because it shifts the question from ‘how...
Drying Filament: Why and How (Dryer, Oven, Dry Box)
A fresh spool of filament straight out of the sealed bag prints beautifully, but after a few weeks on the shelf you suddenly notice popping in the nozzle, stray strings between models, and a dull, pitted surface. Moisture is usually the culprit. Most FDM printing materials are hygroscopic, meaning they actively pull water vapor...
PVA vs HIPS: Soluble Supports for PLA, PETG and ABS
This week’s Monday piece covered multi-color printing with the AMS and how much filament and time every color change eats up. Soluble supports are the other side of the same coin: they run on identical material-swap mechanics, but instead of looks they solve geometry you could not otherwise print in one piece. PVA dissolves...
Engineering Filaments: A Decision Tree for ABS, ASA, Nylon and PC
The previous three weeks of this arc covered the four workhorses of technical FDM printing one by one, each with its own temperatures, chamber requirements and typical failure modes. Now it’s time to put them together. This installment is a recap: it introduces no new material, but arranges ABS, ASA, Nylon (PA) and polycarbonate...
Polycarbonate (PC): High-Temp Engineering Filament for Demanding Parts
When Monday’s topic of the week raised the question of where common engineering filaments stop being enough and when it’s time to reach for industrial-grade materials like Nylon and Polycarbonate, one category of parts deserved a dedicated technical look. Polycarbonate (PC) is one of the most demanding, yet also the most capable filaments available...
Nylon (PA) and PA-CF: Engineering Filaments for Strong Parts
Nylon, or polyamide (PA), is among the highest-performing filaments available for desktop FDM printers, but also one of the most demanding. Standard PLA or PETG handle most hobby projects, but the moment a part has to withstand sustained mechanical loads, vibration, contact with oils, or operating temperatures above 80 °C, polyamides and their carbon-fiber...
ASA: Outdoor Alternative to ABS Without Compromise
Monday’s guide to ABS and ASA covered where PLA’s capabilities end and the world of heat-resistant technical materials begins. This article picks up from there and focuses on ASA as a specific outdoor alternative to ABS, one that solves the biggest weakness of the classic: degradation under UV radiation. If you need to print...
ABS Production Guide: When and Why to Choose It Over PLA
PLA is a great starter material, but as soon as parts need to survive heat in a car, mechanical loads, or repeated use in the workshop, its limits show up fast. That’s where ABS steps in, one of the oldest and still most widely used technical filaments. This guide explains when it makes sense...
Polymaker vs Bambu vs Sunlu vs Prusament: Brand Comparison
The filament market has transformed beyond recognition over the past three years. While the choice used to be between virgin material from a European manufacturer and an anonymous no-name plastic from AliExpress, today you can pick between dozens of brands with similar-looking presentation and very different quality. Among the most frequently compared brands are...
TPU and Flex Filament: Complete Guide to Flexible Materials
Most hobby 3D printers start with rigid materials like PLA, PETG, or ABS. These plastics are strong and reliable, but they can’t bend or absorb impact without cracking. That’s exactly where TPU and Flex filaments come in. Flexible materials open up an entirely new category of applications: phone cases, gaskets, shoe soles, model car...
ABS Filament (4/4): Modern Alternatives and Composites
In our series, we have explored ABS as a strong and versatile material, learned how to print it successfully, and uncovered the magic of its surface finishes. However, the world of 3D printing is constantly evolving, and with it, materials. While ABS remains relevant, modern alternatives have emerged that address some of its shortcomings,...
ABS Filament (3/4): The Magic of Acetone Smoothing and Other Post-processing
If you have successfully mastered the challenges associated with printing from ABS, which we discussed in the previous part, a world of advanced surface finishes opens up for you. It is precisely in this area that ABS absolutely excels and offers possibilities that PLA users can only dream of. The best known of these...
ABS Filament (2/4): How to Tame Printing and Prevent Problems
In the previous part, we introduced ABS as a material with excellent strength and temperature resistance. However, these benefits come at the cost of more demanding printing. While PLA often forgives beginner’s mistakes, ABS requires more careful preparation and specific conditions. The biggest challenges are warping and fume emissions. This article is a practical...
ABS Filament (1/4): Meet the legend of 3D printing
Why was ABS the king of 3D printing? Nowadays, when the world of hobby 3D printing is dominated by easily printable PLA, it’s easy to forget the material that stood at the birth of this revolution. Acrylonitrile Butadiene Styrene, better known by its acronym ABS, was for many years the uncrowned king and the...
PETG in Practice: From Functional Parts to Medical Applications
The theoretical properties of a material are one thing, but the true value of PETG is revealed only in real-world applications. Thanks to its unique combination of strength, toughness, temperature resistance, and ease of printing, it has found its way into workshops, homes, gardens, and even operating rooms. In this final part of our...
Enhanced PETG: A Guide to Composites (CF, GF) and Special Variants
Standard PETG is a fantastic all-around material, but what if your projects demand even higher performance? For applications where extreme stiffness, temperature resistance, specific electrical conductivity, or maximum print speed are crucial, specialized PETG variants come into play. These advanced materials push the boundaries of FDM printing capabilities. In this article, we’ll dive into...
Perfect PETG Surface: A Guide to Sanding, Gluing, and Painting
Printing a model is often only half the battle. For a PETG 3D print to achieve a professional look or meet precise functional requirements, post-processing is essential. Whether you want to remove visible layers, glue a large model together, or give it a unique color and shine, the right techniques are key. Unlike PLA,...
Mastering PETG Printing: Settings, Tips, and Troubleshooting
PETG is celebrated for its versatility, but the path to perfect prints can be paved with minor pitfalls, such as stringing or adhesion issues. Unlike PLA, which is quite forgiving, PETG requires more careful preparation and correct settings. This article is a practical guide that will show you how to tame this material and...
