Start with the filament.
PCL · PLLA · PP · PDO · PLCL · PLGA. Our filament manufacturing experience helps match material, purpose and processing.
Simplified structural diagram. It does not specify copolymer sequence, composition ratio or resin grade.
Standard filaments · 6 materials
PCL
Flexible, with slow degradation.
A comparatively flexible, extensible polyester. It tends to degrade slowly and melts at a lower temperature than PLLA, so heat exposure needs careful review.

What to specify
- Resin grade · Molecular weight
- Flexibility · Elongation
- Post-processing · Thermal history
These are general polymer characteristics. Actual filament properties, degradation and processing temperatures depend on grade, diameter, drawing and test conditions. Melting point is not a safe service temperature or the onset of deformation.
SPECIALTY / PCL
PCL. Two specialty filaments.
Explore VC PCL and PDRN PCL as distinct products. Review their material and appearance, then discuss your specifications.
01Color reference
PCL filament with vitamin C
VC PCL
Slight yellow tintThe addition of vitamin C tends to give the filament a slight yellow tint.

PDRN PCL specialty filament
PDRN PCL
Apricot-like orange tintAn orange tint with an appearance close to apricot.

POLYMER / FILAMENTS
Six polymer filaments.
Discuss supply specifications by material, target diameter, strength and downstream processing.
01Color reference
Standard polymer filament
PCL
Base filament colorA comparatively flexible, extensible polyester. It tends to degrade slowly and melts at a lower temperature than PLLA, so heat exposure needs careful review.
Discuss this filament02Color reference
Standard polymer filament
PLLA
Base filament colorGenerally stiffer and less flexible than PCL, with a higher melting point. Deformation can still occur below melting; crystallinity, drawing and heat treatment affect practical heat resistance.
Discuss this filament03Color reference
Standard polymer filament
PP
Blue with a slight violet tintA polyolefin that does not readily hydrolyze in ordinary moisture conditions. Diameter and drawing affect strength and flexibility; heat and UV exposure can cause aging.
Discuss this filament04Color reference
Standard polymer filament
PDO
Blue with a slight violet tintA degradable polymer generally more flexible than PLLA. Thermal and moisture sensitivity make drying, melt temperature and residence time important processing considerations.
Discuss this filament05Color reference
Standard polymer filament
PLCL
Base filament colorA copolymer of lactide and caprolactone. Its ratio and structure can provide greater flexibility than PLLA while also changing thermal and degradation behavior.
Discuss this filament06Color reference
Standard polymer filament
PLGA
Base filament colorA lactide–glycolide copolymer. Composition, molecular weight and end groups affect degradation and processing; moisture control and thermal history should be reviewed together.

A shared diameter comparison, not GLOONE supply tolerances or test results for a particular PLLA/PCL filament. The EP column refers to absorbable monofilaments; the same size label can have different diameter limits under different standards.
Specify material, pharmacopoeia and edition, size, average diameter range and individual tolerance when ordering. Example: USP 3-0 / average diameter 0.200–0.249 mm. Actual supply limits are agreed separately.
PP is nonabsorbable; PDO, PLLA and PCL are absorbable materials. Confirm knot-pull criteria and test conditions separately. Material names alone do not establish absorption time or strength retention.
Needle gauge and thread USP describe different dimensions. Confirm post-COG dimensions and needle/cannula combinations from model documentation.
