Chinese language 3D printing expertise agency SUNLU has launched a brand new filament drying system designed to supply extra flexibility for 3D printing customers managing a number of spools.
Known as the FilaDryer SP2, the unit separates its heating base from the drying chambers, permitting as much as three chambers to be stacked vertically. This setup is geared toward customers operating a number of printers directly, the place house is proscribed and filament drying usually turns into a bottleneck.
Based in 2013 in Zhuhai, China, SUNLU makes a speciality of 3D printing supplies and {hardware}, with a product vary that features filaments, resins, and equipment. Having offered greater than 25 million items, the corporate runs over 140 manufacturing traces and holds over 200 granted IP rights associated to supplies and tools design.
Scalable design with environment friendly drying
One of many key targets behind the SP2 is to enhance drying effectivity. In repeated assessments with PETG, the system introduced moisture ranges down from 0.6% to 0.2% in simply 4 hours. That’s round 30% sooner than different dryers in the identical class. The adjustable temperature vary, which runs from 35°C to 70°C, makes it appropriate for frequent supplies like PLA in addition to moisture-sensitive filaments reminiscent of nylon.
Every chamber features a built-in humidity sensor for real-time monitoring and gives sufficient house to carry both two 1kg spools, a single 2–3kg spool, or spools measuring as much as 250 mm in diameter and 153 mm in width. The beneficiant capability is very helpful throughout lengthy print jobs, the place smaller dryers usually fall quick. In a single instance, saturated PLA reached optimum moisture ranges inside 4 to 6 hours at 55°C, demonstrating the system’s effectiveness for prolonged use circumstances.
Security options are constructed into the SP2’s design. It makes use of a ceramic PTC heater mixed with a wise fan to make sure warmth is evenly distributed. A mechanical cutoff swap prompts if temperatures spike unexpectedly, whereas a PID-controlled microprocessor retains the system steady inside a one-degree vary.
The machine has handed 72-hour steady operation assessments and was additionally run by means of high-stress eventualities to verify reliability. Further silicone gaskets at connection factors assist preserve moisture out and keep constant drying circumstances.
In comparison with typical dryers, that are usually fastened in design and restricted to a single chamber, the SP2 gives a extra scalable resolution. As an alternative of buying a completely new unit, customers can develop capability by including further chambers. It additionally accommodates smaller spools with out the necessity for adapters or modifications.
Moreover, inside testing signifies as much as 35% decrease vitality consumption than comparable merchandise. In early use, the system has additionally been famous for its quiet operation at 42dB, steady stacking, and constant temperature management throughout prolonged periods.
