Sakata 3D RE-850 recycled filament — recovered-production PLA 850, 1.75 mm, 1 kg

Sakata 3D RE-850 is a filament made in Spain from PLA850 recovered from Sakata's own production process. The manufacturer reuses filament from its production —without adding externally recycled resin— to obtain a material with properties declared as similar to virgin PLA850 while making use of resources that would otherwise remain outside the final product.

It is particularly useful for prototypes, tooling, models, cosplay, fit checks and parts where function matters more than repeating an exact shade. It is supplied as 1.75 mm filament on a 1 kg spool.

Applications

• Dimensional prototypes and assembly tests.
• Tooling, organisers and indoor functional parts.
• Model making, cosplay, draft volumes and parts intended for painting.
• Prints where recovered material is preferred without leaving the PLA850 base family.

Specifications

Print settings

The current product-specific manufacturer recommendation is a useful starting point. The technical data sheet allows a wider window, but each printer should be tuned for flow, layer bonding and first-layer performance.

For long jobs or multiple parts intended to look alike, check the visible shade at the start of the spool. Colour variation does not necessarily indicate a formulation change or defect: it is an expected consequence of mixing recovered PLA850 in different colours.

Properties and heat resistance

Sakata declares physical, mechanical, chemical and thermal properties similar to virgin PLA850 for RE-850. The data sheet publishes reference figures of 50 MPa tensile strength, 2,315 MPa tensile modulus, 3.31% elongation and 118 J/m notched Izod impact. These are results under specific tests, not guaranteed performance for every FFF geometry, orientation or setup.

The published 80-90 °C HDT applies to 100% infill specimens annealed at 110 °C for 15 minutes. An as-printed part must not automatically be treated as suitable for this range.

Storage

Keep the spool sealed with desiccant. If the filament produces popping, bubbles, stringing or rough surfaces, use a drying cycle suitable for PLA and compatible with the spool. Do not directly copy industrial pellet-drying temperatures.

3D-printer compatibility

It is compatible with open-filament FDM/FFF printers accepting 1.75 mm filament, reaching 210-220 °C and providing part cooling. With a tuned profile it can be used on HTA3D HPRO 330 and HPRO 400; Bambu Lab A1, P1 and X1; Creality Ender-3, CR-10 and K1; Original Prusa MK3, MK4, MINI, XL and CORE One; and Voron 0.2, Trident or 2.4.

These machines are conditional examples, not an approval or universal profile. Check spool holder, filament path, sensor and accepted dimensions before using a multi-spool feeder. On enclosed printers, follow the manufacturer's chamber-ventilation guidance for PLA.

Choose it if

• You print prototypes, tooling, cosplay, models or parts intended for painting.
• You accept colour variation in exchange for using production-recovered PLA850.
• You want a material made in Spain with behaviour close to the PLA850 family.

It is not for you if

• You need to repeat an exact colour across parts, spools or batches.
• A uniform appearance matters more than the variable nature of recovered material.
• The application requires food, medical or guaranteed structural certification.

If you require repeatable solid colours, see standard Sakata 3D PLA 850. Special finishes include PLA 850 Fluor, PLA 850 Silk and translucent PLA 850 GLASS. For complex supports, consider Sakata 3D Easy Off for PLA 850.

Print with suitable general ventilation. The filament is not certified for food-contact or medical applications.
