Reduced waste: Because the filament will extrude from the nozzle in good condition, your 3D prints will always come out when they are good (assuming other factors are kept constant). ABS (Acrylonitrile Butadiene Styrene): ABS is a thermoplastic polymer that is widely used in 3D printing. It is moderately hygroscopic and can absorb moisture from the surrounding environment. The presence of moisture in the filament can cause warping and deformation during printing, leading to poor dimensional accuracy. Drying the filament before printing can improve the dimensional accuracy of the printed object. 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. Other than all that, using a desiccant to dry your filament is a common standard nowadays. If you think it meets your needs, be sure to get it. If not, opt for a full-fledged dry box. filament spool compatibleAfter installing the 3KG expansion part, Polyphemus expands from its original 210mm diameter to accommodate a larger 250mm diameter. This increase in size allows for the capacity to hold up to 3kg of filament.
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.The best way to use the PrintDry PRO is as a storage container as well as a dryer. It’s designed so the filament can be fed directly from the dryer to your 3D printer, eliminating the risk of further exposure between removal and printing. Automatic Humidity Control FunctionWhen heating is not required, you can activate the humidity mode and freely set the desired humidity level. The system will automatically activate the heating to regulate the internal humidity according to the set value. This ensures that the filament is always ready for printing.
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. He did mention though that the build quality in his opinion wasn’t at the highest level, but still works nonetheless.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.
In conclusion, the Chefman’s great performance and immense storability make it a first-rate product for your filament drying needs.From a user's perspective, what characteristics does a good filament dryer need to have (e.g. volume, drying result, etc.) 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.
Water molecules can also affect the thermal properties of 3D printing filaments. The presence of moisture in the filament can lower the glass transition temperature (Tg) of the material. The lower Tg can make the printed object more susceptible to deformation or distortion at elevated temperatures. Additionally, the presence of moisture in the filament can cause the material to degrade at higher temperatures, leading to reduced thermal stability. I am pretty happy with Sunlu S2, though for effective drying I have to open the box a few time during a cycle to let it vent a bit. Some sort of timed fan would help here. I also refresh the dessicant in my dryboxes regularly and redry filaments in an oven. Other features that come in handy are automatic timers and presets for different filament drying. One other thing I think the Sunlu comes up short in is the angle of the print opening for drying while printing. The port is just in a weird position. Its just not good for brittle filaments because the awkward angle. This is pretty easy to eyeball if you are looking for it. As referenced below, the red shows the approximate odd angle for full rolls (which isn’t too bad for low rolls). I got around this problem by using a piece of PTFE tube in the port (which appears to be exactly the right size for that, so they likely intended this, but didn’t tell the buyers). This tube allows the filament to bend at a more friendly radius. After using the Aibecy eBOX, people have seen significant differences in their before and after prints. Another thing to add is that there’s no humidity sensor to tell how much moisture is present inside the dehydrator.
Does PLA Need a Dry Box?
The SUNLU Dry Box aims to maintain a constant temperature and prevents excessive heating that could potentially damage the filament. And not all materials are the same - for example BL PAHT-CF seems less suspectible to moisture than Polymaker CoPA. I also have several brands of PETG, some don’t care about moisture at all, others (Devil Design, Extrudr) hate moisture and will foam if left out of the drybox just overnight. PLA is mostly resistant, except when it has some sort of fill, like fibers or CF (though again - BL PLA-CF seems to be pretty resistant). Verbatim PETG claims “hygroscopic”, which is absolutely not true but drybox with some dessicant bags works fine. Many popular materials used in 3D printing, such as PLA and ABS, are hygroscopic, meaning they can absorb moisture from the atmosphere. Moisture in the filament can cause the filament to become brittle and difficult to work with and can cause problems during the extrusion process. When the filament is heated, the moisture turns into steam, which can cause bubbles or voids to form in the printed object. Moisture can also cause problems with adhesion between layers, resulting in a finished product that is weaker and less durable than it should be. 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.） 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.
