Gripper arm 2-finger merupakan bagian dari manipulator atau lengan robot yang memiliki 2 jari untuk mengambil objek benda. Penelitian ini bertujuan untuk mengoptimalkan model dari gripper arm 2-finger dengan memaksimalkan kekuatan serta meminimalkan berat model. Gripper arm dicetak menggunakan mesin 3D printing. Pencetakan gripper arm dibagi menjadi model 1 dan model 2   (model alternative). Pencetakan model dilaksanakan pada infill 60%, 80%,100% dengan sudut arah cetak   45°, 113°, 180° dan material digunakan adalah PLA+ yang mempunyai nilai kekuatan tarik 65 Mpa. Hasil dari penelitian menunjukkan kekuatan tertinggi terjadi pada gripper arm model 2 sebesar 140 N pada pembebanan  horizontal dan 400N pada pembebanan vertikal. Kekuatan terbesar pada model 2, dikombinasikan terhadap pencetakan infill 100% dan arah sudut cetak 45°(vertical) dan pada kombinasi pencetakan infill 80% dan arah sudut cetak 113° (horizontal). Kerapatan infill serta arah pencetakan pada mesin 3D printing berpengaruh pada kekuatan gripper arm yang dicetak.

AbstractPhotopolymerization-based three-dimensional (3D) printing can enable customized manufacturing that is difficult to achieve through other traditional means. Nevertheless, it remains challenging to achieve efficient 3D printing due to the compromise between print speed and resolution. Herein, we report an efficient 3D printing approach based on the photooxidation of ketocoumarin that functions as the photosensitizer during photopolymerization, which can simultaneously deliver high print speed (5.1 cm h−1) and high print resolution (23 μm) on a common 3D printer. Mechanistically, the initiating radical and deethylated ketocoumarin are both generated upon visible light exposure, with the former giving rise to rapid photopolymerization and high print speed while the latter ensuring high print resolution by confining the light penetration. By comparison, the printed feature is hard to identify when the ketocoumarin encounters photoreduction due to the increased lateral photopolymerization. The proposed approach here provides a viable solution towards efficient additive manufacturing by controlling the photoreaction of photosensitizers during photopolymerization.

General Overview

The use of additive manufacturing (AM) technologies is a relatively young research area in modern medicine. This technology offers a fast and effective way of producing implants, tissues, or entire organs individually adapted to the needs of a patient. Today, a large number of different 3D printing technologies with individual application areas are available. This review is intended to provide a general overview of these various printing technologies and their function for medical use. For this purpose, the design and functionality of the different applications are presented and their individual strengths and weaknesses are explained. Where possible, previous studies using the respective technologies in the field of tissue engineering are briefly summarized.
