A recirculating chiller is commonly used to provide liquid cooling to the lasers found in many 3D printers, especially direct-metal laser sintering (DMLS) machines. Recirculating chillers use a pump to circulate the fluid to the 3D printer and a refrigeration system in the chiller to provide cooling. It is important to pair an appropriate cooling system with a 3D printer to ensure that both systems function properly and reliably for many years. This article will discuss five key factors to consider when selecting a cooling system to protect your significant investment in a 3D printer.

1. Consider Cooling Capacity

2. Compare Air- or Water-Cooled Options

3. Review the Recirculating Fluid

4. Evaluate the Electrical Configuration

5. Connect Communications

Laser Chillers from AUWII are designed, engineered and manufactured to supply accurate and cooling stability for a with it advantages by smaller size and lower noise without heat emissions. Especially suitable for cooling water pipe network or cooling tower with high environmental requirements.

During working process of  laser printer, cooling water is needed to cool the cavity of the laser and the galvanometer to keep them in a stable temperature range.

According to laser power, carbon dioxide laser 50W, choose model K2 cooling water circulation machine;

Laser 120W, choose model K2 cooling water circulation machine;

Optical fiber 200W, choose  model K1 cooling water circulation machine;

optical fiber 500W, K1 cooling water circulation machine;

In order to keep the water clean in the waterway, a filter device is required.
