So hardest 3D print I have ever done (and this is take 4). The is a very, very, very accurate (0.5mm in all dimensions) model of the radial and ulnar arteries (arteries in your forearm up to your palm) as part of a radial artery catheterization simulator I am building with a colleague for both interventional radiology and interventional cardiology to train fellows in wire insertion under fluoroscopy, ultrasound and palpating. This is printed in scaffold as we will locate this inside our arm mold and then pour the silicone around it. Sadly 98% of this print is wasted support material, but damn, it freakin' worked. This is about the resolution that simplify3D would even print the artery (when printed closer to horizontal it failed, as I needed the oval to make it printable) as the diameter of the artery is about 2.75mm. Actually not even sure how I can get it off the support, but will try a razor, and can maybe use my hot knife if necessary with the flat cutting blade on it?
