3D Printed Bowel - Portion of Jejenum ModelThis 3D printed specimen presents a small loop of jejenum and mesentery. A window into the mesentery, fat and visceral peritoneum has been removed to illustrate the arterial arcades in the mesentery (many long straight vasa rectae and fewer vascular arcades than in ileum). Also note the presence of lymph nodes (grey-light green) which are a prominent feature of the mesentery, especially near its root close to larger vessels. Classically the fat in the mesentery in the jejenum does not extend to the mesenteric border of the jejenum and would normally allow the observer to view the long straight vessels (vasa recti). However in this example from an individual with a reasonably large amount of abdominal fat, this ‘window’ is not apparent as fat extends further towards the mesenteric border of the jejenum. A small segment of the lumen of the jejenum has been opened to reveal the nature of the mucosal folding (more folds and smaller folds than the ileum).

The models are very detailed and delicate. With normal production machines you cannot realize such details like shown in these models.
The printer used is a color-plastic printer. This is the most suitable printer for these models.
The plastic material is already the best and most suitable material for these prints. (The other option would be a kind of gypsum, but this is way more fragile. You even cannot get them out of the printer without breaking them).The huge advantage of the prints is that they are very realistic as the data is coming from real human specimen. Nothing is shaped or stylized.
The users have to handle these prints with utmost care. They are not made for touching or bending any thin nerves, arteries, vessels etc. The 3D printed models should sit on a table and just rotated at the table.
