SUNLU High Speed PLA Filament 1.75mm Meta Black 1KG Review

Summary

SUNLU High Speed PLA is a 1.75 mm PLA filament rated for print speeds up to 600 mm/s, aimed at makers who want to print fast on a budget.

Strengths

Published spec sheet: diameter, flow, a three-step temperature ladder, density and mechanical data are all listed by the manufacturer.
Low sale price: $11.29/kg on the SUNLU store (2026-10) against a $24.99 regular price.
PLA handling: dry at 65 °C for 8 h and store under 20% RH; no brand lock-in or consumable capsules.
1 kg spool runs about 330 m, so a single spool covers long prints.

Weaknesses

No independent test of this exact HS_PLA Meta Black spool was found; the 600 mm/s claim and ±0.02 mm tolerance rest on manufacturer data.
The only independent review material covers standard SUNLU PLA, a different product, so its adhesion and detail results do not transfer.
No exact-product owner threads were found, so clogs, tangles, brittleness and color consistency are unreported.
“Meta Black” is the Amazon color name; the SUNLU store color list uses “Black”, and whether the shades match is undocumented.
Bed temperature guidance splits: 50–60 °C, or 65–75 °C with glue, so the right setting depends on your plate.
Food-safe caveat: PLA is food-safe as a material, but added toner and nozzle contamination make tableware use inadvisable.

Full research notes and sources

Print speeds and temperatures

The manufacturer publishes a three-step nozzle-temperature ladder tied to speed: 190–210 °C at 50–150 mm/s, 210–230 °C at 150–300 mm/s, and 230–260 °C at 300–600 mm/s, with a 30 mm³/s volumetric flow figure and a 600 mm/s maximum. Bed temperature is 50–60 °C, or 65–75 °C with glue. Whether the spool actually holds dimensional accuracy and surface finish at the top of that range was not independently verified on the pages read.

Moisture, drying and storage

Treat HS_PLA like any PLA for storage: dry at 65 °C for 8 h and keep container humidity under 20% RH with desiccant. The store recommends this routine, and moisture absorption is the usual PLA failure mode if it is skipped.

Evidence and testing

No credible instrumented test of this exact HS_PLA Meta Black spool was found. The only independent review material covers standard SUNLU PLA, which reports good price-to-performance, clean detail and few adhesion issues, but it is a different product and those results do not transfer.

Value

At the SUNLU store sale price of $11.29/kg, HS_PLA is strong value for a high-speed-rated PLA with published mechanical data. Near the $24.99 regular price it is fair-to-weak against established brands unless the high-speed rating is specifically needed. Value depends on the buyer achieving the claimed high-speed quality, which was not independently verified.

Which model this is

This page covers SUNLU High Speed PLA (HS_PLA), 1.75 mm, 1 kg spool, color marketed as “Meta Black” on the Amazon listing (color “Black” in the SUNLU store color list). The manufacturer model number is DCUS-PLAMT-WT-1KG. The Amazon listing for this spool is ASIN B0B1ZV6CJM. Do not confuse it with SUNLU PLA Meta, SUNLU High Speed PLA+, High Speed Matte PLA, High Speed PLA Marble, or standard SUNLU PLA.
