Anycubic 4Max Metal

The Anycubic 4Max Metal is an enclosed desktop FDM printer built for one narrow job: printing in metal. It is designed for 316L metal-filled filament, which becomes functional stainless-steel parts after printing, debinding and sintering. It is a niche machine for enthusiasts and small workshops ready for multi-step post-processing.

The build volume is 270×210×200 mm, with a classic Cartesian motion system, a direct-drive extruder and a 0.5 mm steel nozzle that resists abrasive filament. The hotend reaches 260 °C and the heated bed goes up to 100 °C, with print speeds around 20–60 mm/s. The fully enclosed frame keeps chamber heat in, which is essential for stable metal-filled printing, and the removable platform is held by clamps for easy print removal.

Pros

• Affordable metal printing: after sintering, 316L filament parts become real stainless steel without industrial equipment
• Fully enclosed frame retains chamber heat — a must for stable metal-filled printing
• 0.5 mm steel nozzle and reinforced extruder handle abrasive filament and wear far slower than brass
• Heated bed up to 100 °C with a clamp-held removable platform — prints come off easily
• Full-color touchscreen and simple controls in line with the 4Max family

Cons

• Demanding post-processing: parts must be debound and sintered in a high-temperature furnace, or you get no metal at all
• Heavy shrinkage after sintering (17–25%) requires model scaling and reduces accuracy
• No auto bed leveling, no Wi-Fi and no filament sensor — feature set is basic
• Narrow focus and a high price for a metal-only machine: for ordinary plastic the 4Max Pro is a better buy

The 4Max Metal suits anyone who needs metal parts in small batches: prototypes, tooling, repair spares. It assumes access to a sintering furnace and an understanding of the debinding-sintering process, so beginners without that infrastructure won't need it.

Bottom line: a niche, discontinued printer that made metal printing affordable, but it demands serious post-processing and is tightly focused on 316L filament.
