Additive manufacturing, also known as 3D printing, has begun to play a significant role in the field of medical devices. This review aims to provide a comprehensive overview and classification of additively manufactured medical instruments for diagnostics and surgery by identifying medical and technical aspects. Methods: A scientific literature search on additively manufactured medical instruments was conducted using the Scopus database. Results: We categorized the relevant articles ( 71) by considering the novelty of each proposed instrument and its clinical application. Then, we analyzed the relevant articles by examining the reasons behind choosing additive manufacturing technology to produce instruments for diagnostics and surgery. Possible customization (27%) and Cost-effectiveness (23%) were the main reasons expressed. Technical specifications of the additive manufacturing technology and the material used were also analyzed, and a tendency of using material extrusion technology (35% of the applications) and polymeric materials (86% of the applications) was shown. Conclusions: Additive manufacturing is opening the door to a new approach in the production of medical devices, which allows the complexity of their designs to be pushed to the extreme. However, we found that technical limitations need to be tackled and important aspects such as sterilization or debris contamination are still not considered to be relevant factors during the design and fabrication process. Keeping in mind the challenges of such a new field, additive manufacturing technology can be considered as a great opportunity to provide easy access to healthcare in developing countries as well as an important step toward patient-specific medicine.

“…3D design and printing of surgical equipment has already been attempted and utilised on cadaveric inguinal hernia repair with success in 2017 [7]. Construction and modification of instruments, including a scalpel handle, haemostat, needle driver, forceps, self-retaining retractor, and Army-Navy retractors were done in a matter of days.…”

“…Once established, the actual manufacturing of 3D printed surgical equipment can be much cheaper than their stainless-steel counterparts. Given that the haemostat printed by George et al measures 8cm by 4cm by 0.5cm (16cm3) [7], the cost of a 3D printed haemostat with current material prices (PETG at USD60/kg) can be as low as USD1. This is compared to the commercial price of titanium haemostat which can cost USD10 [15], making a 3D printed version 10 times cheaper than their commercial counterpart.…”

The advancement of 3-Dimensional (3D) printing technology has made the design and production of items increasingly ubiquitous amongst the public. This technology is increasingly being used widely in various medical fields. With its increasing cost efficiency and accessibility, it is the author's perspective that 3D technology can improve accessibility to surgical procedures in low-and mediumincome countries (LMIC) by providing proceduralists with the basic equipment required to perform routine operations.

Surface deformation is a multi-factor, laser powder-bed fusion (LPBF) defect that cannot be avoided entirely using current monitoring systems. Distortion and warping, if left unchecked, can compromise the mechanical and physical properties resulting in a build with an undesired geometry. Increasing dwell time, pre-heating the substrate, and selecting appropriate values for the printing parameters are common ways to combat surface deformation. However, the absence of real-time detection and correction of surface deformation is a crucial LPBF problem. In this work, we propose a novel approach to identifying surface deformation problems from powder-bed images in real time by employing a convolutional neural network-based solution. Identifying surface deformation from powder-bed images is a significant step toward real-time monitoring of LPBF. Thirteen bars, with overhangs, were printed to simulate surface deformation defects naturally. The carefully chosen geometric design overcomes problems relating to unlabelled data by providing both normal and defective examples for the model to train. To improve the quality and robustness of the model, we employed several deep learning techniques such as data augmentation and various model evaluation criteria. Our model is 99% accurate in identifying the surface distortion from powder-bed images.
