Novel Method

A dental implant surgical guide fabricated by 3-dimensional (3D) printing technology is widely used in clinical practice due to its convenience and fast fabrication. However, the 3D printing technology produces an incorrect guide hole due to the shrinkage of the resin materials, and in order to solve this, the guide hole is adjusted using a trimmer or a metal sleeve is attached to the guide hole. These methods can lead to another inaccuracy. The present method reports a technique to compensate for a decreased guide hole caused by shrinkage that can occur when a computer-guided implant surgical guide is fabricated with a 3D printer. The present report describes a technique to adjust the size of the guide hole using a free software program to identify the optimized guide hole size that is fabricated with the 3D printer.

Near Future

3D printer and 3D printing technology are now considered as one of the key factor in the manufacturing industry. In the near future, we could envisage different application of 3D printing method in the sector of materials processing and production. In the sector of civil engineering, they existed somewhere some construction works developed with 3D printing technology.  In this study, we aim to manufacture laboratory-scale printers with nozzles and extrusion feeding systems suitable for paste such as the case of clay-based materials of silicate industry. The movement system was encoded and controlled via the motherboard (Mach 3 controller software). Stepper motors and shaft drives were also implemented in the frame element of such printer. The feeding system was designed based on the extrusion method including cylinder and piston element. Based on that, sample size 200x300x300mm was available for operation testing. Concerning the performance of the instrument, we have obtained printed specimens with different geometric shapes with complexity. From the obtained result, we also discussion on the feasibility up scaling the study and developing a 3D printer for silicate based materials.

3D Printing Technology

3D printing technology is an established industrial practice for rapid prototyping and manufacturing across a range of products, components and commercial sectors and at the same time possesses great potential for every-day life applications to be invented, explored and developed by the coming generations of scientists and engineers. A 3D printer installed in a school setting and complemented by well-designed educational activities can: stimulate the interest and curiosity of students; engage and motivate them into studying science, technology, engineering and mathematics (STEM) subjects, that they may choose or consider as career options; give the opportunity to teachers to achieve content and concept learning in an innovative way. In this paper we present an interdisciplinary science course that was developed for high school students and was implemented in an actual science classroom. The objectives of the course were both to spark the interest and creativity of students and teach them certain curriculum units the content knowledge of which is reached or utilized in an unconventional way. Students are gradually introduced into the 3D printing technology, its application and potential and are assigned a challenging collaborative project in which they have to study, analyse, design and build, using the 3D printer of their school, an operational model of a renown ancient artefact, the so-called Antikythera Mechanism. The mechanism is a 2100-year-old computer and is internationally known as an artefact of unprecedented human ingenuity and scientific, historic and symbolic value. The course involves the teaching of STEM curriculum domains of physics, astronomy, mathematics/geometry, informatics and technology related content and also non-STEM subjects like history and Greek language, both ancient and modern. We give an overview of the course, discuss its various phases and highlight its outcomes.

3D Printing Technology

Purpose The purpose of this study is the use of 3D printing technology to perform maintenance on damaged parts on site. To maintain damaged parts, the user needs experience in the parts design and 3D printing technology. To help users who have little or no experience on 3D printing, a part library-based information retrieval and inspection framework was proposed to support the process of manufacturing replaceable parts using a 3D printer. Design/methodology/approach To establish the framework, 3D printing-based maintenance procedure was first defined, comprising retrieval, manufacturing and inspection steps, while identifying the technical components required to perform the procedure. Once the technical components are identified, part library-based information retrieval and inspection framework was defined based on the technical components and the relationships between the components. For validation of the concept of the framework, prototype system is developed according to the proposed framework. Findings The feasibility of the proposed framework is proved through maintenance experiments on gaskets and O-rings. Originality/value The main contribution of this study is the proposal of the framework, which aims to support the maintenance of damaged parts for the user who has little or no experience in part design or does not know how to operate a 3D printer.

Construction Design

An increasing number of designs and subsequent production of parts created by the Rapid prototyping (RP) [1] technology led to a problem with the maximum workspace of the 3D printer. Due to this reason, it was necessary to work on the solution of joining the parts to overcome the limited workspace of the printer. This article is devoted to glue joints analysis of two parts made by RP technology. A great emphasis is given to the load capacity testing of the parts made this way. The measured values than may serve as a lead for the construction design of the outlined joints. The article builds on the knowledge gained during the previous testing of the screw connections of parts made by 3D printing technology [2].
