Autologous cartilage grafting during open airway reconstruction is a complex skill instrumental to the success of the operation. Most trainees lack adequate opportunities to develop proficiency in this skill. We hypothesized that 3-dimensional (3D) printing and computer-aided design can be used to create a high-fidelity simulator for developing skills carving costal cartilage grafts for airway reconstruction. The rapid manufacturing and low cost of the simulator allow deployment in locations lacking expert instructors or cadaveric dissection, such as medical missions and Third World countries. In this blinded, prospective observational study, resident trainees completed a physical simulator exercise using a 3D-printed costal cartilage grafting tool. Participant assessment was performed using a Likert scale questionnaire, and airway grafts were assessed by a blinded expert surgeon. Most participants found this to be a very relevant training tool and highly rated the level of realism of the simulation tool.

Objective: The aim is to compare between the clinical effectiveness of nasoalveolar molding (NAM) versus the computer-aided design NAM (CAD/NAM) in patients with bilateral clefts. Design: The trial is a randomized comparative trial with 1:1 allocation ratio. Participants: Thirty infants with bilateral complete cleft lip and palate were recruited. Interventions: Patients were randomized between NAM and CAD/NAM groups. The treatment steps described by Grayson were followed for the NAM group. In the CAD/NAM group, digitized maxillary models were made to create series of modified virtual models which were used to fabricate the molding plates using 3-dimensional printing technology. The nasal stents were then added to the plates following Grayson method. The study lasted for 4 months. Main Outcomes: The primary outcome was to evaluate the changes in the intersegment cleft gap. Secondary outcomes included the analysis of the maxillary arch in transverse, anteroposterior, and vertical dimensions as well as the premaxillary deviation and rotation. Chair side time was assessed for both methods. Results: Both modalities decreased the intersegment cleft gap. The CAD/NAM plates caused more reduction in the total arch length by 1.99 mm (−3.79 to 0.19, P = .03) as compared to the NAM treatment. No differences were found between groups in the transverse and vertical maxillary arch changes. Conclusions: Both interventions were effective in narrowing the cleft gap. Similar maxillary changes were found in both groups. The CAD/NAM modality required less chair side time compared to the NAM treatment.

Due to the rapid development of technology, the use of numerically controlled machines in the industry is increasing. The main idea behind this paper is computer-aided design (CAD) based low-cost computer numerical control 2D drawing robot that can accurately draw complex circuits, diagrams, logos, etc. The system is created using open-source hardware and software, which makes it available at a low cost. The open-source LibreCAD application has been used for computer-aided design. Geometric data of a CAD model is converted to coordinate points using the python-based F-Engrave application. This system uses the Arduino UNO board as a signal generator of the universal g-code sender without compromising the performance. The proposed drawing robot is designed as a low-cost robot for educational purposes and aims to increase the student's interest in robotics and computer-aided design (CAD) skills to the next level. The drawing robot structure has been developed, and it meets the requirements of low cost with satisfactory experimental results.

Current and ongoing research and experimentations in the creation, design and build of low-cost, high-value prototypes for novel and unconventional interaction devices (IxD) in combination with cyber-physical system (CPS) (i.e. hybrid design tools (HDT), blended spaces) tangible user interfaces (TUI) and use of sensor technology lead to a variety of novel interaction modalities, experiences and possibilities. In line with this research, we propose a first prototype Human Sensor Selection Tool (HSST) as a preliminary guide and guidelines for design and engineering domains. The HSST is based on and inspired by the ‘five human senses’ [1], a plethora in human body signals (e.g. proprioceptive, vestibular) and gestures (e.g. facial expression, (e-)motions) that could be integrated, translated, transformed, adapted or mimicked to enhance and enrich the interaction modalities with for example computer-aided design (CAD), computer-aided technologies (CAx), and effectively affective CPS.
