In the last few decades, the 4th industrial revolution began - a significant advance in the 3D technology and an emerging of a brand new production method - the computer-controlled additive/subtractive manufacturing. It is considered "the new wheel" and it gives the ability to generate a detailed three dimensional object with complicated geometry from various materials (metals, polymers, clay, biological macro molecules) with a robot, controlled by a computer. The size of the object don't really
The main advantage of the orthopedical presurgical 3d printed models is the possibility to create an accurate model, which can be used for metal osteosynthesis premodelling - the surgeons can prepare (bend, twist, accommodate) the implants prior the operation. After a sterilisation (autoclaving, UV-light, gamma-ray etc etc), those implants can be used in the planned surgery, which will decrease the overall surgery time (in some cases with more than an hour) with all it's advant
There are many challenging cases, in which the single segmentation is not enough. The paranasal sinuses and the congenital heart defects are notable examples. My usual workflow was to segment whatever I can as good as it's possible, to clean the unnecessary structures and the artefacts, to export the segmentation as stl 3d model and then to "CAD my way around". This is solid philosophy for simple, uncomplicated models, but for complex structures with a lot of small details and requirement from
I decided to give my Prusa MK3 printer a real challenge, so I cut my best skull model, I added some slots for neodymium magnets and I started to print the parts. I'm done with the half of them and I'll update my post when I'm done.
The protection of the intellectual property of the 3D models can be a serious issue for every 3D modeler. It sucks when your model is posted for selling at a webside without your consent with a juicy price and you're gaining NOTHING from it. Some 3D artists are adding watermarks to their models, which can be easily removed by an amateur with a free surface modelling program (Meshmixer, Meshlab etc.). But there is an easy solution for this injustice - an invisible watermark. On Watermark3D you ca
My recent anatomy projects forced me to start importing my 3d models into 3d pdf documents. So I'll share with you some of my findings.
The positive things about 3d pdf's are:
1. You can import a big sized 3d model and compress it into a small 3d pdf. 40 Mb stl model is converted into 750 Kb pdf.
2. You can run the 3d pdf on every computer with the recent versions of Adobe Acrobat Reader. Which means literally EVERY computer.
3. You can rotate, pan, zoom in and zoo
This is my first 3D print. I used a 3D model of a kidney, which I made myself from a renal angiography. I printed it with one of my engineer geek friends using a Prusa i3 self-made 3d printer, 0,2 mm nozzle, 0,2mm layer thickness and PLA as material. This was my entering demonstration, which gave me an assignment as a freelancer anatomy assistant professor.
My ambitions are to use 2D and 3D models, along with the traditional cadaver techniques in my work as an anatomy teacher
