Filament Brief History
The first materials for 3D printing were invented in the 80s together with the technology itself. In the last two decades, together with the open-source movement and desktop 3D printing boom, we have been witnessing a significant increase in the variety of produced filaments. ABS material felt strong competition from PLA and PETG that have grown in popularity. The most common filament thickness remains 1.75 mm.
Filament Types
Filament for FDM 3D printers is created from thermoplastics that melts at certain temperature levels. There are many types of plastics that have different properties. PLA is the most popular filament and as it the consumers’ preferred choice, we see a lot of varieties of it. When the composite materials are concerned, the PLA tag might steer the customers towards them, reminding of a trusted filament with mostly predictable outcome. Before mentioning other materials, let’s list all PLA and its popular composites.
– Filament Dryers. It’s important to mention that many filaments tend to absorb moisture, which can significantly deteriorate the quality of both the material and the prints. Fortunately, recent years have seen the introduction of numerous products designed to tackle this problem. Discover more in our comprehensive guide on the top filament dryers and why they are essential.
PLA

Plain PLA (Polylactic Acid) is one of the most commonly used 3D printing materials. You often get a spool of it when you buy a new printer. PLA is normally the first filament used by beginners to 3D printing, as it is expected to have relatively predictable results. However, the quality of PLA may vary depending on the manufacturer. Even filaments from the same manufacturer but of different colors may have different printing properties…

– Tips. In order to print well using such filaments, it is important to sense when and where the transition will occur and what colour shade is preferable at the base and at the top of the print. Models in most cases will be slightly larger than usual to feature the transitions in the desired manner. Sometimes, unspooling the filament until the preferred shade is reached is a good strategy. This may also generate a small bit of filament sample for other single-colour projects.
Thermochromic – Color Changing with Temperature
General settings and recommendations (if PLA):
Nozzle: 210-215°C; Bed: 0-60°C
Nozzle size: 0.4mm

– Tips. When printing with dual and tri-color filament, it’s beneficial to print a test object to determine the color placement on the bed for targeted color sides on your print, although the alignment may shift as the filament unwinds. For better aesthetics on flat surfaces, consider using concentric infill over rectilinear to prevent color striping around features. Be mindful of slicer settings, as they can inadvertently alter color patterns, especially in prints with changing directions like a bowl; employing vase mode can mitigate this but is limited in its application. Smaller up to 100mm height objects tend to keep the color patterns better.
PLA-CF – Carbon Fiber PLA Filament

PETG filament is a 3D printing material for desktop 3D printers that has been quickly gaining popularity. PETG is a polyethylene terephthalate (PET) that is glycol-modified. Before writing this review, we thought about adding the images of makes in PETG to the previous PET filament review that we published earlier. However, after trying to print in it, we realized that it was a different material that required different printing settings, and therefore it deserved a proper review and its separate photo gallery. It is known to be waterproof, but do the models come out really waterproof when printed with desktop 3D printers? Let’s check where PETG filament is used together with its Pros and Cons …

Read more: Flexible Filament Review – TPU, TPE
Flexible filaments, including TPU and TPE, are not as frequently used in 3D printing as PLA or PETG. The reason may be that 3D printing using such materials requires certain skills together with the good knowledge and feel of your machine. Also, slicer settings, like in Cura or Simplify3D, have to be adjusted individually. Not all objects can be printed in flexible material. For example, designs with joint parts, that work well in PLA or ABS, may require modification to suit flexible filament. This post is updated frequently with brief reviews, pros and cons, and ideas for 3D printing.

Filament Innovations
Some filament manufacturers are confident enough to bring novel materials and solutions to the market adding diversity to 3D printing.
– Antibacterial PLA. Smart Materials company MatX is introducing an innovative anti-microbial filament with unique properties. Let’s have a quick look at AMBX PLA, learn about the company, and see what other products and innovations they are working on.
– NoneOilen. Recent notable material was created by Fillamentum. 100% biodegradable, reusable without losing properties, and food-safe NoneOilen won a 3DPI award for Fillamentum.
– Eco-friendly Spool Options. Despite many attempts to reuse leftover spools, a lot of them still end up in the landfill. Even recycling such spools is not ecological enough. Some 3D printing material manufacturers are taking more action and driving the implementation of new green industry standards.

– Refills & MasterSpool. Richard Horne aka @RichRap3D who tirelessly promoted cardboard spools, in the end, published an ingenious reusable spool system. A so-called MasterSpool was designed to carry filament refills. DAS FILAMENT, the German filament manufacturer, quickly responded to the MasterSpool initiative and within days offered their customers to buy refill only.
Conclusion
Here we briefly mentioned some of the most popular filaments for FDM 3D printing. As filament manufacturers work hard to produce something new and interesting, we, as consumers, enjoy the abundance of variety. The more confident we grow with 3D printing, the higher the anticipation to try even experimental materials.
