Quick Answer

How does TPU glow in the dark and how long does it last?

The filament is loaded with photoluminescent pigment that charges from sunlight or indoor light and re-emits a soft glow for hours in darkness; longer charging gives a brighter, longer afterglow.

Frequently Asked Questions

How does TPU glow in the dark and how long does it last?
The filament is loaded with photoluminescent pigment that charges from sunlight or indoor light and re-emits a soft glow for hours in darkness; longer charging gives a brighter, longer afterglow.
Will glow TPU print on my printer?
Yes on direct-drive printers — Bambu Lab A1/X1 and Creality K1 with direct drive handle flexible TPU well; Bowden machines can print it too, with slower speeds and careful retraction settings.
What settings work best for TPU flexibility?
Use 220 °C nozzle, bed 40-50 °C or even none, and a slow first layer; TPU bonds best with minimal cooling and slightly increased flow for that cushion-like, tear-resistant structure.
How many soles can I print from one 250 g pack?
A 250 g pack of 1.75 mm filament is roughly 75-85 meters, enough for several pairs of slipper soles or a batch of straps and grips depending on size and infill.
What do the eight colors look like?
The range pairs matte pastels — Dawn Green, Apple Green, Clear Water Blue, Macaron Yellow, Lavender — with high-visibility Fluorescent Orange, Pink and Blue for night-safety footwear.
What speed should I use for flexible TPU?
Keep speeds at 20-40 mm/s for flexible TPU; slower extrusion prevents buckling in the hot end and keeps layer fusion strong for flexible, wearable parts.
Is this for shoe production or general flexible parts?
Both — the 95A shore hardness is ideal for slipper soles, insoles, straps and grips, and equally good for gaskets, phone cases and other soft functional parts.
How should flexible TPU be stored?
TPU absorbs moisture quickly; keep spools vacuum-sealed with desiccant until use and store opened rolls below 20% humidity to prevent bubbles and weak layers.
