No fume extraction port for your 3D printer? We offer ideas and solutions.

There’s more than one way to capture the particles produced by 3D printers.

Put the printer in a hood

A customer decided that the most appropriate solution for his situation was the one shown in the conceptual image below: a MakerBot Replicator in a Model 330 Ductless Containment Hood.

Each side wall of the hood has an opening for the printer’s power cord.

This hood is lightweight and easily re-located because it is not physically restricted to the location of permanent ductwork.

This kind of flexibility is good for growing organizations.

Alternate between applications?

Perhaps you can alternate use of the hood between applications.

For example, do your 3D printing  a few days a week, then remove the printer and put your laser pen set up in the hood for engraving tasks.

The correct filtration set will trap both particles and fumes produced by both applications. Now that’s efficiency.

Work closely with your Sentry Air applications specialist to identify the correct filtration set.

Create an exhaust port

For situations where a ductless fume hood won’t work, consider making a fume exhaust for your 3D printer to connect to your fume extractor.

In a three-part tutorial, the local children’s museum Maker Annex guru documented how he used the space’s tools to add a fume exhaust port to a MakerBot Replicator.

He used a laser cutter, a rivet tool, and a collar, a standard component of many of our fume extractors.

Via the newly created fume exhaust port, the flex hose connects the printer to a Model 300 Portable Fume Extractor.

At the Maker Annex, they alternate 3D printing with laser cutting.

They placed the Model 300 near both the laser cutter and the 3D printer.

To prevent fumes from spreading through the space, they attach the flexible hose to the tool that will be in operation.

We’ve posted a blog about their excellent set-up for maker kids.
