eSUN is a major Chinese filament distributor. eSUN produces by far the cheapest filament available at half the price of many other top brands when purchased through Microcenter’s Inland brand. You read that right: for around $15 you can buy a spool of decent quality filament!

If you go to almost any forum on the internet and search for eSUN reviews you will see nothing but praise for the brand and mostly high scores for important filament qualities such as strength, color, dimensional accuracy and reliability.

Along the same lines, out of the dozens of customer reviews on Amazon for eSUN products, the majority of positive. Customers have found that eSUN produces great quality ABS with less warping than other brands.

eSUN also produces PLA with some of the best dimensional accuracy available among the brands that sell cheap filament spools for under $20.

The Filament: Price, Quality, and Color Range


For a few years eSUN has been the go-to filament supplier for many third-party filament brands in the US and internationally. eSUN quality is good enough and cheap enough that many of these brands have been able to undercut the filament market based completely on price.

Also, eSUN is a company that both produces cheap filament and is also devoted to research and development of new Plastics, which is rare. Cheap filament producers don’t usually have the interest or capital to invest in R&D. The fact that eSUN does both means that the company is constantly producing new types of materials and improving on old version of its products. This allows it to stay on the cutting edge of the filament industry by constantly expanding its range of more specialized materials such as PETG, PLA+ and ABS+.



eSUN filaments sell on for between $20 and $25 depending on the type of plastic and the distributor. Amazon has two brands one of which is eSUN itself and the other being Intservo. Intservo also has its own website as a standalone brand. But the prices aren’t much different there. Of course, by far the cheapest place to find filament from eSUN is on Micro Center’s website. The Microcenter filament brand is called Inland, and costs around $15 per Spool. That is cheaper than any other brand out there worth buying. How is Microcenter able to offer filament at such low prices? Inland is simply eSUN filament offered at almost no markup. By not marking up eSUN filaments, Inland has been able to capture a large portion of the filament Market.

eSUN color range is just about as wide as it gets. They offer every color you could want including many specialty colors and specialty materials. eSUN might not offer all of the colors it produces through its in-house eSUN brand but you will be able to find almost all of the colors through its third party distributors such as Inland and Toybuilder Labs. Of course, eSUN specializes in the most popular colors and produces them on mass scales. eSUN also offers a limited color range for certain products such as the PLA+ and ABS+ filaments. However, eSUN will be expanding its color offerings for these specialty products soon.

Quality and Materials


eSUN is very reliable and will give you good prints over and over again. That being said, over the course of printing with dozens of rolls, you will sometime see more hiccups in filament quality and consistency than with other more expensive 3D filament brands. However, unless you are ordering filament by the pallet, eSUN will be a perfect low-cost alternative to some of the more expensive filaments available. So if you are looking to explore a new color or just add to your filament arsenal, head over to Microcenter and pick up an Inland spool for just $15.

eSUN PLA is known for its fantastic adhesion properties. It also has excellent opaqueness, good color tone and excellent variance. Some spools of eSUN PLA filament have been known to have a variance of less than +/- .01 millimeters – it doesn’t get much better than that! Although it might take a few tries to calibrate the temperature and settings of your printer, once you do you will be very happy. This PLA seems to work best when printed at a temperature of 210ºC for the first layer and dropping it from there to about 200 – 205ºC.

Every once in a while a spool of eSUN from some brands will be a dud and cause some problems such as clogging. But this is not the norm for eSUN and you should simply try a different brand. Each brand has a different quality control contract with eSUN, so make sure you find the brand that works best for you. See above for more information about different brands. For the most part eSUN PLA is good quality from unbeatable price.

ABS from eSUN is a consistently good quality plastic filament. eSUN ABS has good diameter, good strength and seems to print well in a relatively wide temperature range from 215ºC to 245ºC without problems. It rarely clogs printer nozzles and doesn’t leave any residue behind inside extruders. This is a great filament to start with for new 3D printers learning to print with ABS. And, judging from the positive reviews on Amazon, eSUN ABS is the ABS filament brand of choice for many seasoned 3D printer enthusiasts as well.

eSUN wood filament is hands down one of the best wood filaments available on Amazon for around $25. It prints well but strings sometimes. However, it looks very much like wood and with a little bit of post-processing with sandpaper, objects printed with this filament will look convincingly like wood. It feels like wood, it looks like wood and it will stain well. The most interesting thing about this filament and however is that it has almost no smell at all and as a result probably doesn’t contain any wood any actual wood. The only downside to this filament besides the slightly higher price is that it is a bit delicate. But since it is a wood filament, some lack of strength is to be expected and will probably be fine for most projects.

QUICK TIP: Like all PLA, wood filament isn’t very heavy, so to really convince someone that it is wood, you might want to wait your pieces internally. You can do this by drilling a little hole in the bottom of the piece and inserting small weights that you can find on Amazon or in hobby shops.

PETG filaments are quickly replacing PLA and ABS as the go-to filaments of choice for many 3D printer owners. That’s because PETG has all of the best qualities of both PLA and ABS, plus it is food safe and FDA approved. eSUN PETG filament is no exception. Judging from the dozens of positive reviews on this filament is one of the most popular PETG brands available.

For many 3D printing enthusiasts, this filament is the only filament they use. As one customer put it there is no need to use any filament other than the PETG from eSUN.

Cleaning Filament

The eSUN cleaning filament is HDPE Polyethylene, the same stuff that milk jugs are made of. It’s super cheap and works really well. This cleaning filament works best by running it through extruder twice, first at a high temperature around 240ºC and then a second time pulling it through gently at around 100-110ºC. The first time through the extruder will get a lot of the gunk out of your extruder. But the second pass is where the deep cleaning will happen. Basically, if you are looking for a cheap cleaning filament, then look no further. Get a spool on Amazon here.

However, you can’t buy eSUN products directly from the Shenzhen eSUN Industrial company website. Why? We’re not sure. But we suspect that it has something to do with eSUN’s business model, which relies heavily on filling large orders from third-party sellers.

YOU SHOULD KNOW: Not all rebranded eSUN filament from third party distributors is the same and the quality of eSUN filament could vary substantially from one supplier to the next. The reason for this is that each supplier has a separate contract with eSUN and these contracts have different quality control standards built in. This means that one brand may or may not perform quality control checks as thoroughly as the next brand. Just beware of this difference.

Here is a quick run down of the major eSUN brands:

Microcenter / Inland

  • For a cheap filament, the diameter of Microcenter filament is surprisingly consistent.
  • Some warping on overhangs but easily fixed with fans.

Recommended Printer Settings


Printer settings for eSUN products tend to be similar to all other PLA ABS and PETG filament from other brands.

Since recommended temperature for most products tend to fall between 200ºC and 220ºC it’s safe to say that these filaments require a little bit more attention when calibrating your printer. However, once calibrated these filaments will print well for you almost every time.

  • Print PLA = 200-210ºC
  • Print ABS = 215-245ºC
  • Print wood filament at = 210ºC
  • Print PETG filament at = 230-250ºC
