SJSato Posted May 27, 2015 Share Posted May 27, 2015 Had some time over Memorial Day weekend so I downloaded Dr. Mike's Lumbar Spine model. Believe it or not, this was a 65 hour print on my Ultimaker 2! All in all, the print came out pretty well. I have a web cam watching over the printer and can monitor progress over my iPhone. I can also shut down the printer remotely if the printer goes haywire. Link to comment Share on other sites More sharing options...
Dr. Mike Posted May 30, 2015 Share Posted May 30, 2015 Wow that is incredible! Great job and thanks for sharing your results. I presume that you printed this free lumbar spine file. Did your Ultimaker have to print a lot of support structure for this particular model? Link to comment Share on other sites More sharing options...
SJSato Posted May 31, 2015 Author Share Posted May 31, 2015 I used the Ultimaker's Cura software to generate the support structure and there was quite a bit of support , maybe a little overkill. It came off fairly easily but quite a bit rougher than the unsupported surfaces. I'll post a picture of the underside when I get back to the lab.

SJSato Posted May 31, 2015 Author Share Posted May 31, 2015 Here is the ugly underbelly of the print. With some sanding and finishing I could get it a bit smoother. When I paint models I use a spray primer with a filler. That would also eliminate small defects and the striations from the printing. Considering the complexity of the model and the limitations of my printer it came out better than expected. 3D printer companies are working on dual head printers that will extrude the support material in dissoluble material which may ease a lot of the problems of printing overhangs. Dual head printing is still a bit buggy however and real hasn't made it mainstream, at least in the hobby level printers. Ultimaker has abandoned their attempt to add dual heads to their line of printers. Link to comment Share on other sites More sharing options...
Dr. Mike Posted June 2, 2015 Share Posted June 2, 2015 That's amazing. Even with the roughness from the support, the print still looks really good. If you don't mind my asking, what are you using the prints for? Education, research, or just for personal interest? Link to comment Share on other sites More sharing options...
SJSato Posted June 9, 2015 Author Share Posted June 9, 2015 Dr. Mike, mainly I like to print biomedical models for personal interest and curiosity. I am trying to get more adept at segmenting out my own models from scans but I'm still on the upward slope of learning. At this point, it is just a geeky hobby.

Dr. Mike Posted June 10, 2015 Share Posted June 10, 2015 Keep up the good work. It is a valuable skill set to develop. Trust me. Link to comment Share on other sites More sharing options...
vlad Posted March 2, 2016 Share Posted March 2, 2016 Can you please share your slicer settings and filament choice or recommendations? I've had some good results with humoral head and elbow joint printed in white PLA with 3-4 outer shells for cortex and I've played with 20% infill and 50% infill for medullary center. I'm trying to find ideal infill density for drilling and would also like to see if other plastics offer some benefits over the PLA. Link to comment Share on other sites More sharing options...
Freeflightoo Posted February 15, 2019 Share Posted February 15, 2019 Where can I find files to print a full sized sacrum and the L5 vertebra above it, but print both separately? Any help on this one? Link to comment Share on other sites More sharing options...
Dr. Mike Posted February 19, 2019 Share Posted February 19, 2019 You might want to check the spine and pelvis download area. https://www.embodi3d.com/files/category/13-spine-and-pelvis/ Link to comment Share on other sites More sharing options...
