While PETG (glycol-modifed polyethylene terephthalate) is somewhat more difficult to print compared to PLA, the end parts are mechanically stronger and more resistant to temperature. If you’re looking for a filament that holds up better outdoors or in weight-bearing applications, PETG is a good choice for you. Keep in mind that the filament may lose some strength if it encounters excessive moisture, so store your PETG rolls in a dry box if possible.

Sunlu PETG is a great choice if you’re looking for a cost-effective PETG that you can rely on. Although it’s a filament that requires experimenting to find the ideal printing parameters for your printer, once it’s locked, you’ll be able to consistently produce strong pieces on demand.

Community feedback on Sunlu’s PETG includes the need to dry the filament before each print or else inadequate first-layer adhesion or bubbling on the surface may become an issue. It’s also been suggested to avoid printing this filament too fast, especially the initial layers.

• Colors: 9
• Recommended settings: Hot end 220-250 °C; heated bed 75-85 °C
• Sizes: 1.75 mm; 1 kg
• Price: ~$24/kg for PETG; ~$12/kg for variants

Variations

• Recycled: Similar to the recycled PLA, Sunlu recycles any PETG that doesn’t make it onto the rolls during production. This recycled PETG option comes at a reduced price, but similar to their recycled PLA, it lacks the replacement guarantee.

ABS (acrylonitrile butadiene styrene) is one of the strongest filaments that’s widely available, but it can be finicky to print. Without proper temperature control, including the use of an enclosure, ABS is highly prone to warping. However, once dialed in, ABS can produce a relatively high-temperature resistance that’s great for electronic cases and other structural prints.

Members of the 3D printing community consider Sunlu’s ABS formulation to be not only inexpensive but also one of the best ABS filaments on the market. Sunlu’s consistency can also be counted on for their ABS line. While ABS may not be generally recommended to someone just getting started with 3D printing, Sunlu has set out to change that with their Easy ABS (see more on that filament below).

• Colors: 8
• Recommended settings: Hot end 250-260 °C; heated bed 80-120 °C
• Sizes: 1.75 mm; 1 kg
• Price: ~$18/kg for ABS; $12-25/kg for variants

Variations

• Easy ABS: Sunlu claims that their novel acrylonitrile butadiene styrene ratio in the Easy ABS filament has created a significantly more printable ABS without sacrificing the material’s functional properties. Easy ABS’ advantages include a lower printing temperature and no enclosure necessary. Many users would agree that it’s easier to print, but it might not be a bad idea to use an enclosure, just to be on the safe side.
• Recycled: In addition to PLA and PETG, Sunlu offers a recycled ABS option made from production waste. Like the others, it comes at a reduced price but lacks the replacement guarantee.

ASA (acrylonitrile styrene acrylate) is the easier-to-print alternative to ABS that many regard as a complete replacement for ABS in your filament library. It’s perfect for pieces that need durability and resistance to sunlight, such as planters and car accessories.

Community members declare Sunlu ASA to be a great value for the price considering it prints very easily. The only primary drawback is that it may not be as widely available as other options like Sunlu’s Easy ABS. While ASA is slightly more expensive than ABS, it may be worth it to guarantee the lifespan of your parts.

• Colors: 6
• Recommended settings: Hot end 245-255 °C; heated bed 80-120 °C
• Sizes: 1.75 mm; 1 kg
• Price: ~$27/kg

TPU (thermoplastic polyurethane) sets itself apart from the other common filament options for being soft and flexible. Bear in mind that flexible filaments can be tricky to get right, especially with Bowden extruders, as the filament tensioner must be finely tuned and the nozzle can become easily clogged due to under-extrusion and charring of the sticky filament.

Sunlu’s TPU has a 95A shore hardness, which is pretty average for a flexible filament. Sunlu enthusiasts note that Sunlu TPU has a better-looking and shinier surface finish than other TPUs on the market. Most makers find success with small prints, which are readily squishable.

• Colors: 7
• Recommended settings: Hot end 205-230 °C; optional heated bed
• Sizes: 1.75 mm; 0.5 kg
• Price: $36-$40/kg

Sunlu has always been known for their 3D printing accessories, and the Filadryer line has been no exception. One of the largest problems for 3D printing enthusiasts has always been filaments’ tendency to absorb water, causing everything from surface imperfections to failures. Sunlu has a few solutions to offer:

Filadryer S1

The original Filadryer S1, priced at around $40, includes a temperature controller and timer. It works well for both initial drying and temperature holding during prints. You’ll need to know your desired settings for each filament, and the spool does need to meet some basic size and width restrictions.

Filadryer S1 Plus

The S1 Plus comes with all the same features but also has a fan installed to prevent overheating and aid in water removal.

Filadryer S2

You can also grab the newest S2 filament dryer from Sunlu for approximately $80. This smart little box comes with presets for different types of filaments, as well as the ability to measure relative humidity inside the chamber. While the S2 has a larger footprint compared to the S1, it includes a fan, a larger touch screen, and more programmable features. Spooling the filament through the top can be somewhat clumsy, but all of the best intentions are there.
