[labnetwork] Experience with Creatbot 300 PEEK printer

[J_Hagopian at comcast.net]

Hi Christian,

Thank you for your insights... we will do some experiments with various PEEK fills and lattice structures and do the inspections you have suggested.  Also perhaps some testing in a vacuum chamber with qcm or mass spec.  Will let you know how it turns out in a few months.

Regards,
