HEPA filter + Carbon filter gives the user a peace of mind (and lack of odor) during long duration prints.

MakerBot Clean Air can be monitored through the UI display on the Method series.

Production version

Final product after rounds of DFM and cosmetic review.

Process:

Initial form explorations

Through a series of emission testing, the team determine that the filter needs to be placed slightly above the Method lid for effective filtration. The next step involves exploring potential forms for the exterior filter housing.

Chosen form

This design was chosen to be further explored since it blends well with the form of the Method. Below are some part count explorations for this design.

Simplification

The previous iterations require too many parts and have a relatively complex filter changing experience.

The design is simplified into two main modular parts. The team later decided to change the  round filter to a rectangular one for emission reasons.

Quick mock up render to show part count:

Filter change

Option 1: magnetically attach

The top housing would snap to the clear housing magnetically through 4 sets of magnets. A strip of sheet metal will be glued to the clear housing. The filter is sandwiched in between the gap between the two. This was the selected option ultimately.

Option 2: pivot lock

The top housing would feature a filter cover that can pivot. The user would have to take off the entire housing to insert the filter.

Option 3: turn lock

Top housing features 4 rotating locks that keeps the filter in place. The user would need to remove the entire housing to access.

Top housing form exploration

Magnetically attach emerged as the best experience for filter change. For the next step, we explored some form options for the top housing.

USB, Power, connectivity placement.

Ports placement was also explored during the top housing development process.
