Advantage:
Storage
PLA - PLA responds somewhat differently to moisture, in addition to bubbles or spurting at the nozzle, you may see discoloration and a reduction in 3D printed part properties as PLA can react with water at high temperatures and undergo de-polymerization. While PLA can also be dried using something as simple as a food dehydrator, it is important to note that this can alter the crystallinity ratio in the PLA and will possibly lead to changes in extrusion temperature and other extrusion characteristics. For many 3D Printers, this need not be of much concern.
Smell
PLA - PLA on the other hand, being derived from sugar gives off a smell similar to a semi-sweet cooking oil. While it certainly won't bring back fond memories of home-cooked meals, it is considered by many an improvement over hot plastic.
Part Acuracy:
PLA - Compared to ABS, PLA demonstrates much less part warping. For this reason it is possible to successfully print without a heated bed and use more commonly available "Blue" painters tape as a print surface. Ironically, totally removing the heated bed can still allow the plastic to curl up slightly on large parts, though not always.
PLA undergoes more of a phase-change when heated and becomes much more liquid. If actively cooled, much sharper details can be seen on printed corners without the risk of cracking or warp. The increased flow can also lead to stronger binding between layers, improving the strength of the printed part.
Strict Quality Control:
Production procedure
I . Before produce extruding filament ,we will dry ABS and PLA for a enough time (3-5 hours).
II. Mix with colors masterbatch or colors powder, all which .certified with ROHS.
III.Adjust temperature and dragging rate , make filament diameter range at 1.6-1.8mm/2.8-3.0mm,
roundness +/-0.05mm, each spool net weight 1kg+/-0.02kg
IV we put all filament spool in shelf, different kind in different shelf, all categories arranged orderly.
Quality Control
I. we have diameter laser detect kits to control extruding rate on line, when diameter smaller or higher than accept range, the laser detect kits will adjust the extruding rate higher or smaller to make diameter range at acceptable.
II.keep each record filament samples sent to customers, build a tracking able document.
III.when the filament
