A desiccant screams filament drying on a budget. It’s obviously the cheapest entry on the list, and works for maintaining the moisture levels of your filament without absorbing more afterwards.
PLA doesn’t need a dry box to 3D print but using one can help produce optimal surface quality. PLA is known to be hygroscopic which means to absorb moisture from the environment. When PLA or filament has absorbed moisture, it can get brittle and even lead to print failures, as well as blobs/zits on your prints. The PrintDry PRO holds up to 4 spools of 3D printing filament at once, and even has adjustable temperature controls which make it especially ideal for PLA and ABS users.While others have praised how it’s very effective for drying Nylon and PETG, and some also spoke of the great customer service, many complained about the absence of a humidity sensor. Another thing to add is that there’s no humidity sensor to tell how much moisture is present inside the dehydrator. This, in particular, is well-liked among people who have bought the SUNLU Dry Box. They say that it was able to dry their filament and make it as good as new.
After putting the spool of TPU in the dryer box, it definitely did its job in allowing him to successfully 3D print some awesome models consistently. Since purchasing this product, he hasn’t had any further issues with filament moisture. You might not want it for you’re looking for a standalone filament dryer. Where this product really shines is making an already dried filament stay dry for an extensive period of time. In short, it does make your prints much better than they were before, but there are a few things that you should know about this dry box.However, one of the most apparent downsides to this filament dryer is that it is only able to store one filament spool at once. As compared to other dryers, this comes off as a significant con. Rather than use an oven for this Nylon which can be troublesome and not temperature-accurate, he put the spool of Nylon in the filament dryer for 12 hours at 70°C (the maximum temperature) using the useful timer feature, and it completely dried the filament like it was a new spool. Nylon: Nylon is a synthetic thermoplastic material that is known for its strength and durability. It is highly hygroscopic and can absorb moisture from the surrounding environment. The presence of moisture in the filament can cause issues such as warping, deformation, and reduced mechanical properties. Drying the filament before printing can improve the mechanical properties of the printed object. It’s worth noting that while vacuum-sealed bags are the best way to keep away moisture and dust, they won’t dry out the filaments if they’ve already been exposed, nor will they control the temperature at which the filaments are stored. printing is a process that creates three-dimensional objects by depositing successive layers of material on top of each other. It is also known as additive manufacturing. The most common materials used in 3D printing are thermoplastic filaments, such as PLA and ABS. Moisture can accumulate in the filament, causing problems during printing, such as warping and poor adhesion. A filament dryer is a device that uses heat and a controlled environment to remove moisture from the filament, ensuring that it is dry and ready for use in 3D printing. This can improve the quality of the final printed object and reduce the likelihood of printing failures.
To use a desiccant, you have to get yourself an airtight container or bag that can comfortably store your 3D printer filament. The size of the container entirely depends on you. So for those printing with just PLA or ABS, the single spool Sunlu Dry Box suffices. But makers employing exotic filaments on multiple printers will find the S4’s ample drying capacity and swift moisture removal well worth the added investment. Compared with the mainstream filament dryers currently on the 3D printing market, we believe that Polyphemus is leading in terms of functionality.Moreover, its transparent viewing window makes it easy to monitor what’s happening on the inside while the dehydrator does its thing. PLA (Polylactic Acid): PLA is a biodegradable thermoplastic polymer that is derived from renewable resources such as corn starch or sugarcane. It is less hygroscopic than ABS and is less prone to absorbing moisture. However, the presence of moisture in the filament can still cause issues such as poor adhesion between layers and clogging of the printer nozzle. Their melting point is around 135°C so be sure not to heat them up to that point, or else their Tyvek wrapping will soften and render the whole operation useless.
eSUN is a highly established name in the 3D printing world. They’re very well known for making high quality filament, environment-friendly resins, and now, they’ve come up with a brilliant filament dryer as well. At the same price, is a single spool filament dryer or a multi spool filament dryer is more suitable for you in your usage scenarios?（We are talking about ‘unit price’ here, one spool slot is recorded as 1 unit price.） One user who had many failed prints with TPU went out to research exactly why this was happening. After some time, he found out that TPU is actually very hygroscopic, meaning it absorbs plenty of moisture in the nearby environment. If you’re really on a budget, or simply have no real use for the added features of commercial filament dryers, then your best option is standard vacuum seal bags. If you’ve bought your own filament recently, it more than likely came vacuum sealed. By default, it maintains a temperature of 50℃ and dries for six hours straight. Otherwise, you can always long-press this machine’s left button to adjust the run time.Some people use ovens to dry their filament, but not all ovens are calibrated so well at lower temperatures, so they may be a lot hotter than you actually set. Filament dryers are like storage boxes for your filament with temperature and atmosphere controls to create the best environment to increase the longevity of your filaments. Just be ready to take some time to learn the unintuitive LCD controls. But with handy presets for different filaments, it’s easy to get great results once you get the hang of it. eSun eBox
