3D printers are large investments for any business, so it's important to maximize returns wherever possible.

Use the opportunity to both protect the user and improve your part quality.

protect the user and improve your part quality

TAKE ACTION TODAY TO HELP IMPROVE YOUR ROI

The average price of industrial 3D printers is rising, with new technology, materials and faster processes demanding a higher price point. Additionally, with technology moving so fast – companies are spreading the capital expenditure of their machines over shorter and shorter time frames. It has never been more important to improve your return on investment by improving the quality of the parts printed and extending the life of your printer.

Thermal management

Users of 3D printing will understand all too well the difficulties with finding optimum printing parameters to avoid common problems such as deformation and lack of strength. It is becoming more common knowledge that for most 3D printing processes; to improve the quality of printed parts, one must be the master of temperature distribution across that part. Controlling heat will ultimately give the user control over the material’s phase and therefore the final quality of the print.
Most commonly a user typically has two controllable variables at their disposal to manage this; bed and nozzle temperature. A third parameter that is starting to be included in new printer specifications is chamber air temperature, i.e. active convection. The ability to control the speed and temperature of circulating air which directly impacts the rate of cooling of any print.
BOFA systems actively move air within 3D printers, therefore can be used for active convection. There are two main configurations in which a BOFA system can be used to help aid temperature control within a 3D printer:

Open loop

A configuration in which the BOFA system is pulling air from within the 3D printer, filtering, then pushing into the local environment. This configuration results in a net heat loss from within the 3D printer. This setup can be advantageous when attempting to keep air temperatures lower than otherwise would be found when printing without extraction.

Closed loop

A configuration in which the BOFA system is pulling air from within the 3D printer, filtering, then pushing back into the 3D printer. This configuration results in heat stability or increases within the 3D printer. This setup can be advantageous when attempting to keep air temperatures higher or more stable than otherwise would be found when printing without extraction.

Both configurations can help improve thermal gradients during 3D printing, depending on what is being printed and by which process. With tighter control of thermal gradients, one has better control over quality-related issues such as distortion and strength loss.
