3D-Fuel Standard PLA+ | Industrial Gray | 1.75mm | Made in USA

Pure NatureWorks Resin. No Fillers. Made in the USA. In Industrial Gray.

No-nonsense, clean, and professional — Industrial Gray is the workhorse color of the Standard PLA+ range. A cool, neutral mid-gray that lets the geometry of your print do the talking, it's the default choice for functional parts, prototypes, and any print where color is secondary to form and precision.

3D-Fuel Standard PLA+ is built on a simple premise: start with the best raw material and don't compromise it. Every spool is made from 100% virgin NatureWorks™ Ingeo 4043d PLA resin — no fillers, no stretchers, no blending agents. The result is a more predictable, consistent printing experience, spool after spool. Because no fillers are altering the melt behavior, you may find the ideal print temperature runs 5–10°C higher than your usual PLA settings — dial in from the lower end of the recommended range and adjust from there.

It's an easy-to-print, hard plastic with a pleasant, barely-there sugary scent during extrusion. The AMS-compatible spool makes it a natural fit for multi-color workflows on Bambu Lab systems, and it's been tested across a full range of printer brands for reliable performance wherever you run it.

Available in 1kg and 4kg spools — choose your spool size when adding to cart.

The dependable everyday gray for makers and professionals — perfect for:

• Functional parts, enclosures, brackets, and mechanical components
• Engineering prototypes and concept models where form matters more than color
• Architectural scale models, structural details, and presentation pieces
• Jigs, fixtures, and workshop tooling
• Multi-color Bambu Lab AMS workflows requiring a reliable neutral gray
• Prints intended for post-processing — priming, painting, or surface finishing
• Any project where a clean, professional neutral is the right call

Printer Compatibility: Compatible with most 1.75mm FDM 3D printers. AMS-compatible spool. Tested in-house on Bambu Lab, Creality, Prusa, Raise3D, MakerBot, LulzBot, FlashForge, and more.
