Specification Brand : Sovol BulletPoint1 : 【Photosensitive PLA Filament】 Sovol light change PLA filament contains photosensitive materials, which can change color rapidly after absorbing UV light energy. Without UV light, the filament appears white. Only expose it to UV lights for 10 seconds, the white filament would fast change to purple and keep it in purple for 1-2 mins. During these 2 mins you can experience various shades of purple, and then the filament will return to white. You can also achieve an irregular white-purple gradient effect by shielding some parts of your prints from UV light BulletPoint2 : 【Imported PLA Raw Material】The raw material comes from the US, and it has been developed and modulated to show a charming gloss on the PLA. No jam, no bubbles, no tangle, and no layer line. With perfect first layer adhesion to reduce warpage, shrinkage, curl and print failure BulletPoint3 : 【Easy to Print】Full mechanical winding and strict manual examination, to make sure the line tidy, so as to avoid possible snap and line breaking; Larger spool inner diameter design makes feeding smoother. The diameter tolerance of this 1.75 PLA filament is +/- 0.03mm. More stable diameter tolerance of 3D printer filament would bring you smoother 3D printing experience. Universal compatibility with most FDM 3D printers and 3D Pens BulletPoint4 : 【Cardboard Packaging】Instead of plastic spools, we use paper spool and paper box to package PLA filament. The PLA filament is vacuum packed with high quality desiccant to keep dry BulletPoint5 : Any questions we will be here to help! BulletPoint6 : In order to reduce possible warping of the first layer, we recommend preheating the hot bed temperature to 55-65 degrees, reducing the printing speed of the first layer to 25mm/s, and setting the line width to 0.6mm or the flow rate to 150%, excessive fan cooling in cooler weather will worsen edge warping.
