PETG color update
PETG Rainbow Purple-White Filament Winding for OEM Color Review
This 26-second factory video shows pale-purple filament winding onto a black spool, with lighter sections visible across the wound material. A finished spool label reads PETG Rainbow. The material and rainbow purple-white color are identified by WJ; the footage itself documents the winding and finished spools rather than laboratory performance or dimensional tolerances.
Quick answer for buyers
WJ presents PETG rainbow filament in a purple-white color, identified by WJ and shown winding onto a black spool. Buyers can discuss the gradient reference, filament diameter, spool format, label and carton for custom-color PETG; request a physical sample or sample print before confirming an OEM order.
What the winding video shows
The camera stays close to one winding station as glossy, pale-purple filament travels through a guide and onto a black spool. Darker purple and much lighter sections can be seen across the growing wound surface.
At the end, the camera moves to finished black spools in a blue bin. One visible label says PETG Rainbow. The video does not establish diameter tolerance, net weight, transition length or output capacity.
How gradient length changes the printed result
For multicolor filament, transition length and the amount of filament used by a model affect which colors appear and how quickly they change. A small print may show fewer transitions than a larger object even when both use the same spool.
Ask for a physical spool sample or sample print that represents the intended color sequence. Evaluate the color in normal viewing light and record the approved reference for repeat purchasing.
Planning an OEM filament color order
An OEM filament color specification should separate appearance from measurable product requirements. Confirm the purple-white reference and expected transition behavior, then document material grade, filament diameter, spool net weight, spool dimensions and packaging.
For private-label supply, provide label and carton artwork after the sample is approved. Agree inspection criteria, order quantity and delivery timing before bulk production.
Production overview
WJ 3D Printer Filament Factory shares a close view of PETG rainbow purple-white filament winding and labeled finished spools. Use the video as visual production evidence, then send your color reference and order specification to request an OEM quotation.
Procurement notes
| Gradient reference | Confirm purple-white appearance, color order and expected transition length with a physical sample or sample print. |
|---|---|
| Filament specification | State PETG grade, filament diameter, dimensional criteria and intended printing application. |
| Spool and packaging | Confirm net weight, spool dimensions, label files, carton artwork and protective packaging. |
| Order approval | Agree the approved sample, quantity, inspection criteria and delivery timing before production. |
