Formlabs Form 4 Mixer
Formlabs Form 4 Resin Mixer — Optimal Material Homogeneity & Print Consistency The Formlabs Form 4 Resin Mixer is an essential accessory designed to maintain uniform resin properties and maximize print quality across the Form 4 and Form 4B SLA 3D printing ecosystem. By continuously mixing and circulating liquid resin within the tank during operation, it prevents pigment settling and resin separation, ensuring reliable curing and predictable mechanical properties print after print.
Keeps Resin Homogenous and Consistent Formulations with high pigment loads or specialized additives can separate over time. The Form 4 Resin Mixer continuously agitates the resin inside the tank to deliver consistent viscosity and uniform color distribution throughout short or extended print runs.
Embedded Failure Detection Sensor Designed with intelligent hardware integration, the mixer incorporates an embedded cured resin sensor. This safety feature actively monitors for cured debris or unexpected blockages in the tank, allowing the system to abort risky prints early and protect your printer hardware from damage.
Independent, Reusable Design Unlike previous generations, the Form 4 Resin Mixer operates independently from the resin tank itself. While it can be thoroughly cleaned and transferred between different resin tanks or material types, having a dedicated mixer for each resin tank is strongly recommended to streamline material changes and prevent cross-contamination.
Long-Lasting Durability Built for high-throughput additive manufacturing environments, a single Form 4 Resin Mixer typically lasts for the entire lifetime of your resin tank or longer, making it a cost-effective solution for continuous production.
