Yousu vs ZIRO Filament Specs
Dimensional accuracy
Both brands list a filament diameter of 1.75mm with a tight tolerance of ±0.03mm. This specification is critical for consistent extrusion and preventing nozzle clogs. Yousu highlights this precision alongside an automatic spooling system and double drying process to ensure bubble-free prints. ZIRO also specifies the ±0.03mm tolerance, noting it contributes to tangle-free and clog-free performance. Since the published dimensional accuracy is identical for both products, neither holds a technical advantage in this specific metric.
Print speed
ZIRO provides explicit print speed recommendations, suggesting a range of 30 to 90mm/s for optimal results. This gives you a clear upper limit for how fast you can run the printer without compromising quality. Yousu does not list a maximum or recommended print speed in its published specifications. While Yousu mentions compatibility with most printers, the lack of a stated speed limit means you must determine the safe operating range yourself. ZIRO offers more direct guidance here.
Surface finish
Yousu offers a Silk PLA finish, described as shiny and gorgeous without requiring polishing or coating. The bundle includes specific colors like silk gold, white, silver, and pink, designed for high-detail aesthetic prints. ZIRO focuses on a Metal Series finish, specifically copper in this listing, which infuses metal powder to create a metallic appearance. Yousu targets users wanting a smooth, reflective sheen, while ZIRO targets those seeking a textured, metallic look. They serve different aesthetic goals.
Package contents
Yousu sells a bundle containing four individually vacuum-packed spools, each weighing 250g, totaling 1kg. This multi-pack approach provides variety in colors and reduces the need for multiple shipments. ZIRO lists a single spool with a net weight of 1kg (2.2lbs). However, ZIRO includes bonus items such as an extra resealable bag for storage and a notecard for customer support. Yousu wins on quantity of filament, while ZIRO wins on included accessories.
Material source
Yousu explicitly states that its PLA is produced from Natureworks Ingeo plastic pellets made in the USA. This specific material source can influence consistency and reliability during long prints. ZIRO does not disclose the origin or brand of the raw plastic pellets in its published data. Knowing the base material is USA-made provides Yousu with a transparency advantage regarding material origin, which may matter for supply chain preferences.
Which filament fits your project
Users needing varied silk colors
The Yousu bundle includes four 250g spools in distinct silk shades like gold, white, silver, and pink. This multi-pack allows you to print diverse projects without switching filaments. The smooth silk finish provides a shiny surface that requires no post-processing. You get a complete net weight of 1kg, ensuring you have enough material for larger builds or multiple smaller items in one purchase.
Printers seeking metallic appearance
The ZIRO Metal PLA offers a distinct copper finish that mimics the look of metal. It is designed for extrusion temperatures between 190 and 220 degrees Celsius. The filament maintains a consistent diameter tolerance of plus or minus 0.03mm to prevent clogs. It comes in a single 1kg spool, vacuum sealed with a desiccant to keep the material dry and ready for use in your 3D printer.
Those wanting extra storage
ZIRO includes a bonus resealable bag along with the vacuum-sealed primary packaging. This extra bag helps you store partially used filament securely. The filament itself features a metal-infused PLA composition that reduces bubbles and tangles. With a net weight of 2.2 pounds, it provides a substantial amount of material for your prints while maintaining the dimensional accuracy required for precise 3D printing.
