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. Another user has pointed out that they would prefer a manual on/off button on the Dry Box since the current way of doing that demands a few too many presses from you.
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.） Here is a brief comparison of the effects of water molecules on some commonly used 3D printing filaments: Second in this list is the SUNLU Dry Box for 3D printer filament storage, a cheaper option than the EIBOS Filament Dryer Box. This spool holder is compatible with filaments of 1.75 mm, 2.85 mm, and even 3.00 mm comfortably. While people have loved what this dehydrator brings to their fruits and various foods, it’s also worth noting that Chefman’s multi-functionality brings great value for your money. Another thing to add is that there’s no humidity sensor to tell how much moisture is present inside the dehydrator.Compared with the mainstream filament dryers currently on the 3D printing market, we believe that Polyphemus is leading in terms of functionality. More expensive than other options. But, it’s the best filament drying box around – you get what you pay for. 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.
It’s dust-proof, sealed properly, and has enough space for 4 rolls of 0.5KG filaments, 2 rolls of 1KG filaments, or 1 roll of 3KG filament. There is even a built-in fan to circulate the hot air inside the whole dryer box, improving the moisture removal. 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. Water molecules play a crucial role in hygroscopicity and diffusion. When a hygroscopic material is exposed to water vapor in the air, water molecules can be absorbed into the material through diffusion. Diffusion occurs because water molecules tend to move from areas of high concentration to areas of low concentration until an equilibrium is reached. The rate of diffusion is influenced by temperature, humidity, and the concentration gradient between the material and the surrounding air. Materials with polar functional groups are more likely to attract water molecules and are therefore more hygroscopic. Additionally, this figure not only includes filament spools of the regular 1.75 diameter, but you can also fit in 3 mm filaments as well. This just makes Chefman the best filament dryer in terms of storability.Thee spacious chamber, multiple heater fans, and compatibility with various materials make the S4 perfect for those constantly switching filaments across multiple printers. A few users have actually tested the temperatures that are displayed on the dryer box and they say it’s accurate. The ease of use is one of the main reasons why so many users love this machine.
One unique feature that makes the Aibecy eBOX stand out is its weight scale. As you use your filament spool, it tells you by weight how much your material is left. 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.
Does PLA Need a Dry Box?
What people have really admired about this dryer is how it’s able to store and dry filaments for long print jobs, making them fit for prolonged usage. 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. Using a filament dryer can also help remove moisture from the filament before printing. By controlling the moisture content of filaments, it is possible to produce high-quality 3D printed objects with improved mechanical, thermal, and electrical properties.
While standard Sunlu Dry Box is a great budget option for drying a single spool of filament, enthusiasts using multiple materials will want to invest in the S4 when it’s released. Continue by sealing the desiccant dryer inside the enclosed box right alongside your filament. This will help keep the moisture at bay and keep your material dry. You can also use it to store and dry your food, apart from 3D printing filament. People have admired its ease of use, easy cleaning, and top-notch effectiveness. 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. From a user's perspective, what characteristics does a good filament dryer need to have (e.g. volume, drying result, etc.)
He previously tried other filament dryer boxes, but didn’t get results as good as with this one. An old 2-year spool of Nylon was giving him issues because it wasn’t sealed properly in a bag.
