Introduction: Recent advances in three-dimensional (3D) printing technology have made it possible to print surgical devices. We report our initial experience with the printing and deployment of endoscopic and laparoscopic equipment. Materials and Methods: We created computer-aided designs for ureteral stents and laparoscopic trocars using SolidWorks. We developed three generations of stents, which were printed with an Objet500 Connex printer, and a fourth generation was printed with an EOSINT P395 printer. The trocars were printed with an Objet30 Pro printer. We deployed the printed stents and trocars in a female cadaver and in vivo porcine model. We compared the printed trocars to two standard trocars for defect area and length using a digital caliper. Paired T-tests and ANOVA were used to test for statistical difference. Results: The first two generations of stents (7F and 9F) were functional failures as their diminutive inner lumen failed to allow the passage of a 0.035 guidewire. The third generation 12F stent allowed passage of a 0.035 guidewire. The 12F diameter limited its deployment, but it was introduced in a cadaver through a ureteral access sheath. The fourth-generation 9F stents were printed and deployed in a porcine model using the standard Seldinger technique. The printed trocars were functional for the maintenance of the pneumoperitoneum and instrument passage. The printed trocars had larger superficial defect areas ( p < 0.001) and lengths ( p = 0.001) compared to Karl Storz and Ethicon trocars (29.41, 18.06, and 17.22 mm

“…Although the average consumer in many places with a vibrant Open Source community can already realize significant economic benefits from purchasing a RepRap 3D printer to manufacture goods for themselves (Wittbrodt, et al, 2013), the average consumer is far less technically saavy than any laboratory that itself might outsource manufacturing. For this reason the competitive pressure from distributed manufacturing of Libre Hardware would seem to be focused on engineers, applied scientists, makers/tinkerers, hobbyists and first adopters until the ease of use for both digital manufacturing hardware (e.g.…”

The number of libre designs have been shown to be growing at an exponential rate (Wittbrodt et al, 2013) and a single repository now holds more than 1 million designs.…”

The rise of Free and Open Source models for software development has catalyzed the growth of Free and Open Source hardware (also known as "Libre Hardware"). Libre Hardware is gaining significant traction in the scientific hardware community, where there is evidence that open development creates both technically superior and far less expensive scientific equipment than proprietary models. In this article, the evidence is reviewed and a collection of examples of business models is developed to service scientists who have the option to manufacture their own equipment using Open Source designs. Profitable Libre Hardware business models are reviewed, which includes kit, specialty component, and calibration suppliers for makers. The results indicate that Libre Hardware businesses should target technically sophisticated customers first and, as usability matures, target expanded markets of conventional consumers.

In the last few years a significant growth of three-dimensional printing has been noticed. Although 3D printers have been around for about 30 years, they were very expensive, that is why they were available in the industry only in the majority . In recent years, prices of 3D printers have fallen more than tenfold, owing to the fact they are used not only in large enterprises but also in all kinds of educational institutions, small businesses or in do-it-yourself men's houses. They are, inter alia, used to construct physical models, so much needed in education. Nowadays, one of the most popular 3D printing technologies is FDM (Fused Deposition Modeling). Relatively low prices of printers in this technology make them available for almost everyone. The paper discusses the technology of rapid prototyping, with particular emphasis on the use of 3D printing and appropriately matched printer to designed laboratory stand.
