Fiberlogy is a Polish company with a team of enthusiasts constantly seeking innovation, so naturally they couldn’t miss recycled filament. This company offers one of the most extensive listings on the market for recycled filaments, and each one is made of 100% recycled material. You’ll not only find PLA and PETG, but also ABS, nylon, and PP. However, availability is limited, and the only color choice is black for all of the material options.

To deliver only premium filament quality to the customer, the raw material is carefully sourced to avoid contamination. The material is then stored and processed under strict control to obtain the best filament quality. For this reason, their recycled filament maintains the properties of virgin material but also comes at a premium price.

You can find the recommended print settings on their website for each kind of filament. The instructions are quite detailed, including hot end and bed temperature, fan and printing speeds, flow rate, surface and chamber type, retraction values, and drying conditions. You really can’t go wrong here!

• Materials: PLA, PETG, ABS, nylon, PP
• Color: Black
• Sizes: 1.75 mm (0.75-0.85 kg)

Prusa Research is probably a name you’ve heard if you’re into 3D printing, as they’ve developed a few popular printers like the Prusa i3 MK3S+. They also make a variety of filament types, branded as Prusament, and you can get recycled versions of their PLA and PETG filaments. The raw material used for Prusament recycled filaments is the waste material generated during the manufacturing of their regular PLA and PETG filaments.

It’s also worth mentioning that Prusa only sells recycled PETG in 2-kg spools, and they maintain a decent +/- 0.05 mm diameter tolerance. Additionally, Prusa states that every batch of recycled filament comes in a different color, so you can’t choose exactly what you want – don’t be surprised that there’s no color choice at checkout. With recycled PLA, there are four color options in addition to the gray 2-kg spool, but you can still expect slight variations from batch to batch.

Prusament recycled filaments are overall pretty good when it comes to material properties. As they’re recycled from regular Prusament PLA and PETG, the filaments have many of the same high-quality characteristics, such as high-temperature resistance for the PETG and super easy printability for the PLA. On a similar note, you can find a few different print setting recommendations on Prusament’s website for each of the recycled filaments, which can help you improve the quality of your prints.

• Materials: PLA, PETG
• Colors: PLA in browns, orange, cream, and a gray shade that varies by batch
• Sizes: 1.75 mm (1 kg, 2 kg)
• Price per kg: $31 (or $45 for a 2-kg spool)

Protoplant is one of the most well-known manufacturers of premium filaments. Their values are quality, reliability, creativity, and environmental awareness. For this reason, they have created their Recycled PLA filament line. Most of their normal PETG line is also made with up to 75% recycled material.

Made from their own recycled waste, the recycled PLA filament is offered in black and 13 other shades that are distinguishable from the classic PLA thanks to a touch of glitter. There’s often a wide variety of colors to choose from, but keep in mind that every batch is a limited edition because the unique color depends on the combination of recycled scraps and therefore won’t be restocked. Furthermore, you can test out this filament in black for a low price thanks to the expanded sizes they offer: You can buy the most common 1-kg spool, a 500-g spool, or a 50-g coil.

A happy user achieved flawless prints by printing this filament at the maximum recommended temperature settings, so 225 °C with the bed heated at 60 °C, as well as slightly slower speeds. You can also try printing at the speed you normally use for PLA, and if there are problems, decrease the speed in 10 mm/s increments until extrusion is consistent.

• Materials: PLA, PETG
• Colors: Black and several limited edition colors such as mint, purple, and teal
• Sizes: 1.75 mm (1 kg)
• Price per kg: ~$30

Printerior is a fascinating company that produces almost only recycled filament. They offer both recycled PLA and PETG in numerous colors. While their rPLA is recycled from food packaging waste, rPETG is produced from industrial scrap. They are so committed to reducing 3D printing waste that they offer their own recycling service. You can order one of their bins to fill with your filament scraps. Once you send it back to them, you unlock discounts for your purchases of more filament.

With their mission to produce high-quality filament from recycled feedstock, Printerior has developed a custom process to produce a recycled filament that prints as well as virgin material. Their recycled filaments are produced from at least 97% recycled materials and up to 100% when colorants aren’t added.

To help you get started, they recommended some print settings that should lead you to great results. For the rPLA, they suggest a hot end temperature between 195 °C and 225 °C, while for the rPETG they recommend printing at 230 °C to 250°C. For the bed temperature, whatever normally works for the respective filament type should be sufficient.

Filamentive is a manufacturer and seller of recycled filament with different percentages of recycled content (e.g. 70% recycled plastic). They offer recycled filament in a wide range of materials, including composites such as wood and less common materials like ASA. They even have different finishes for their filaments, like matte and speckled.

Filamentive filament has a tolerance of +/- 0.05 mm according to the manufacturer, and even though it’s recycled, there’s no loss of mechanical properties. They state that their filament is 97% round, too.

They ship their filaments in recyclable packaging, and the filament is on a cardboard spool, further pushing their recycling efforts. They offer filaments in a few different sizes for select options, from sample sizes to 8.5 kg as well as in 1.75-mm and 2.85-mm diameters.

One customer observed that the filament comes in a unique color selection and maintains a steady tolerance. The customer also mentioned that the filament has a lower melting temperature than most normal PLA filaments.

3DJake is one of the most popular online retailers of 3D printing supplies, selling 3D printers, filaments, and accessories from many different manufacturers. They also make their own filaments, including rPLA, a filament that’s 100% recycled and sourced from the scraps of 3DJake’s ecoPLA filament. According to 3DJake, these scraps are organized by color and shredded into grains to be reused to make rPLA filament.

Although ecoPLA filament comes in 23 colors, rPLA is only available in 8, including orange, green, red, blue, white, and more. Unfortunately, at the time of writing, only the orange filament in 2.85 mm is still available, and it doesn’t seem like there are plans to restock.

As for printing, 3DJake states that rPLA is easy to print and will yield minimal shrinkage, making it great for printing dimensionally-accurate models. Unfortunately, some user reviews suggest otherwise, stating that prints in the filament came out very inaccurate. On another note, while 3DJake is based in Europe, they now offer free shipping to the US.

• Material: PLA
• Color: Orange
• Sizes: 2.85 mm (0.25 kg)
• Price per kg: ~$43 (~$11 for 0.25-kg spool)

3D-Fuel is a manufacturer of a variety of filaments, like tough PLA, ABS, ASA, PETG, and more. Like many filament manufacturers, 3D-Fuel ends up with a lot of filament scraps as a by-product of their regular filament manufacturing processes. To reduce their environmental footprint and avoid throwing this excess plastic out, 3D-Fuel created ReFuel, a line of filament made out of their scraps from making their Standard PLA+ and Pro PLA+ filaments.

It’s worth noting that ReFuel filament can come in a few different colors, but the color you receive isn’t known and varies by batch. Unfortunately, 3D-Fuel only offers this recycled filament in a 1.75-mm diameter in a 1- or 4-kg spool, which often sells out quickly.

• Material: PLA
• Color: Varies by batch
• Sizes: 1.75 mm (1 kg, 4 kg)
• Price per kg: $20-$24

Although big companies, such as Prusa, use industrial machines to produce recycled filament, makers can do it too! DIY recycling is an exciting topic that has become very popular in the last few years. Bottle recycling machines, like the one from ecodecat, are among the many projects you can find online.

Producing filament from your own 3D printed scraps is significantly more intensive than bottle recycling, but it can be even more rewarding. The main components you’ll need are a shredder, an extrusion unit, and a filament winder. Each of these components is expensive, with higher quality machinery being able to produce better quality filament. Advanced makers out there looking for a challenge may have great fun with the trial-and-error required to set up such a system.

If you’re curious about it and want to know more about this topic, check out our article on filament recycler options to get started.
