Sky Blue Color PLA Brand: Yiqiu3D · Model: White PLA · Filament that tangles, clogs, or strings ruins both 3D pen doodles and full prints. Chengfan Basic PLA is refined for no-clog, no-stringing flow, keeping 3D pen tips clear and FDM nozzles clean from the first meter to the last.
Clogs and stringing come from inconsistent melt flow and moisture. This PLA is compounded with clean, uniform polymer flow at the listed 220°C and shipped dry, so the melt stays stable at the tip and nozzle, reducing blockages and wispy strings during printing and 3D pen drawing.
Full answers belowBest for: A dependable choice for beginners and everyday print jobs on any FDM printer, with no heated chamber needed - available in 9 colours; 1kg spools; lead colour White PLA. Not ideal for: Avoid outdoor use and continuous stress - switch to ASA for UV and weather exposure - available in 9 colours; 1kg spools; lead colour White PLA.
Nozzle 190-220°C
Artists and hobbyists judge filament by color truth. This PLA line covers 8 everyday colors - Black, Red, Green, Skin Tone, Yellow, Orange, Blue and Sky Blue - with solid, even pigmentation for clean doodles and crisp models.
A clogged nozzle is usually a diameter problem in disguise. Chengfan PLA uses a consistent 1.75mm round cross-section with tight winding, so the filament feeds smoothly through narrow 3D pen channels and standard hotends alike.
Nothing is more frustrating than a pen that stops mid-line. At the listed 220°C this PLA melts evenly with low stringing, gliding through 3D pens and FDM printers from Creality and Prusa without fussy retraction tuning.
