the enclosure less than ABS right off the bat. Make sure to print with an enclosure fan
and monitor the internal temperature, which should ideally be in the 30-35C range or
lower if you can get it.
If you'd like to lower the temperature further, you can always buy a more powerful fan,
but the easiest thing to do is crack the front door a little to increase airflow. But won't
that let out all of the volatile organic compounds coming off the hot end? The key is
the negative pressure combined with the particles' minimal and light.
As you can see, the fan keeps the air flowing in and the harmful particles floating into
the vent or filter.
3D Printer Design Matters
The other part of the equation is the printer design. Those printers where the hot end is
at the top of the enclosure make it easier to achieve higher temperatures because the
hot air rises to the top, and the vertical hot end position is fixed. Those printers with
the hot ends at the bottom will always have more problems managing temperature
simply because the temperature is more likely to vary as the hot end goes from the
bottom to the top of the enclosure.
