    Mike, we use college kids to run our 3d department they are engineering students or biology majors or sometimes graphic arts majors so they all know CAD design and anatomy but the rest is just winging it We have over 50 printers churning out 3d patient models 24/7 The containers are self-produced they are basically designed for dog food so they have a seal on the lid. The hygrometers are cheap and crappy on eBay or Amazon. The fittings to connect the PTFE tubing is on Thingiverse as well as the roller spool holders I think the later is called TUSH or something similar. You will need standard roller bearings the type used in fidget spinners 4 per spool again Amazon or eBay Each costs about $25 total and about 3 hours of printing time to print all the parts The commercial boxes like the one you suggested is a total rip off as are the dedicated filament driers We bought a REALLY high-end fruit jerky dryer in stainless for like $80 on eBay and it holds several rolls at a time Sorry I don't have actual links to send you to for the various files and or products but the one is here https://www.amazon.com/IRIS-Nesting-Airtight-Container-Large/dp/B007RBB6UI/ref=sr_1_5?s=pet-supplies&ie=UTF8&qid=1526232975&sr=1-5&keywords=dog+food+storage That is the dog food container Get back to me if you can't find the rest I will get one of the kids to help us out here Dr. D

    Mike We use a food dehydrator for ALL of our filament We simply toss the rolls inside and turn it up to max which is significantly lower than the alteration point of all commercial filaments and then dry them for 12 hours and IMMEDIATELY remove them to a plastic container that has a series of spool rollers inside and outlets for the filament to exit. The containers have gaskets so no leaking The filament is never allowed to see the humidity of Florida it goes from dehydrator (or the new box) then into the container which has 2 pounds of rechargeable desiccant as well as a digital hygrometer inside it than thru PTFE tubing to the extruders of the dedicated printer next in line to be used. The added length of PTFE does add a BIT to the retraction issues of the printers but they do fine once adjusted The containers hold about 6 rolls of filament Hope this helps Dr. Dave

    This week we want to share with the embodi3D community the seven most downloaded models from the dental, orthodontic and maxillofacial category. Uses of 3D printing include the production of drill guides for dental implants, the production of physical models for prosthodontics, orthodontics and surgery, as well as the manufacture of dental, craniomaxillofacial and orthopaedic implants, and the fabrication of copings and frameworks for implant and dental restorations. The most downloaded file is an STL model of a woman's mandible. This model was 3D printed by an embodi3D member with excellent results. Be sure to click through and check out this STL file and images of the resulting 3D dental print. The list also includes other great 3D dental models. Don’t forget to register and download the STL files so you can 3D print the models yourself. Please reply to this post with which model you like best. 1. An excellent 3D model of a woman's mandible with great detail. 2. This model was created from a conebeam CT and segmented on itk-snap. 3. A highly detailed dental scan shows the bony anatomy of the maxilla, mandible and facial structures in great detail. 4. 3D model of the mandibula with details of the teeth 5. A 3d model of the mandible for implant study. 6. Digital model of the orbit with the frontal bone shown. 7. A beautiful STL file 3D model of parasymphyseal and subcondylar mandibular fractures. Please reply to this post with which model you like best or if you know of a good file which should be included post it here. References 1. Dawood, A., Marti, B. M., Sauret-Jackson, V., & Darwood, A.

    Nevit has done some tremendous work. Check out his blog article on using Osirix to create color MRAs. http://nevit.blogspot.com.tr/2018/04/how-to-creat-color-mr-angiography-using.html

    Shannan, I was able to print the slices without having to go through Meshmixer. I am using a Prusa MK3 i3 and just put the files in the Slic3r PE and it printed flawlessly. the slicer did find few holes but they were automatically fixed. Look at my review and you will be able to see the result. Eric

    Thank you very much for the files, I printed the 4 slices in a total of 64 hours in PETG red. It does take some time, but the result is fantastic. I printed it for my teacher of BIO A&P, she is a crazy about anything related to cardiovascular. I added small 5 x 1 mm earth magnets to hold the slices together. They seem to be te right thickness to compensate for the gap between each slices. Over all, I love that model. I will have to reprint the top slice as my part started to unglue from the bet and has some warp. What you do is awesome and giving it access for free is marvelous. Again thank you for your work Eric I will be starting on the heart attached to the spine very soon
