Factors Affecting

Open-source 3D printer has been widely used for fabricating three dimensional products. However, this technology has some drawbacks that need to be improved such as accuracy of the finished parts. One of the factors affecting the final product is the ability of the machine to extrude the material consistently, which is related to the flow behavior of the material inside the liquefier. This paper observes the pressure drop along the liquefier by manipulating the nozzle die angle from 80° to 170° using finite element analysis (FEA) for polymethylmethacrylate (PMMA) material. When the pressure drop along the liquefier is varied, the printed product also varies, thus providing less accuracy in the finished parts. Based on the FEA, it was found that 130° was the optimum die angle (convergent angle) for extruding PMMA material using open-source 3D printing.

Fused Deposition

Fused Deposition Method (FDM) merupakan salah satu metode 3D printing yang paling populer digunakan. Teknologi FDM menawarkan proses manufaktur yang relatif lebih cepat dan murah bila dibandingkan dengan CNC atau injection moulding. Pada FDM, filament diumpankan ke dalam ekstruder yang dipanaskan pada temperatur tertentu kemudian didorong keluar melalui sebuah nozzle untuk menghasilkan lapisan-lapisan objek. Hingga saat ini, banyak komunitas yang menghasilkan mesin-mesin 3D printer skala kecil karena proyek-proyek teknologi 3D printing bersifat open-source. Masing-masing komunitas memiliki standar tersendiri dalam membuat mesin 3D printer sehingga salah satu masalah yang timbul dari aktifitas ini adalah akurasi objek hasil 3D printing yang kurang seragam. Penyimpangan geometri akan mempengaruhi proses desain dan produksi objek-objek hasil 3D printing. Hal ini terutama dalam pembuatan objek-objek yang memerlukan proses pemasangan/perakitan. Artikel ini bertujuan untuk mengetahui penyimpangan geometri objek hasil 3D printing yang dihasilkan dari mesin 3D printer FDM DIY. Pembuatan objek menggunakan 3D printing DIY mengalami deviasi pada dimensi geometri dan posisi. Deviasi geometri bervariasi dari -0,08 mm hingga +0,14 mm. Sedangkan deviasi posisi berada di rentang -0,08 mm hingga +0,12 mm. Berdasarkan data deviasi yang dihasilkan dari perbandingan di atas, maka pembuatan objek 3D printing dapat disesuaikan dengan simpangan masing-masing. Hal ini menjadi penting untuk mendapatkan objek dengan akurasi yang maksimal sehingga proses perakitan komponen dapat dilakukan dengan mudah dan sesuai dengan peruntukannya.

We present a robotic platform based on the open source RepRap 3D printer that can print and maintain chemical artificial life in the form of a dynamic, chemical droplet. The robot uses computer vision, a self-organizing map, and a learning program to automatically categorize the behavior of the droplet that it creates. The robot can then use this categorization to autonomously detect the current state of the droplet and respond. The robot is programmed to visually track the droplet and either inject more chemical fuel to sustain a motile state or introduce a new chemical component that results in a state change (e.g., division). Coupling inexpensive open source hardware with sensing and feedback allows for replicable real-time manipulation and monitoring of nonequilibrium systems that would be otherwise tedious, expensive, and error-prone. This system is a first step towards the practical confluence of chemical, artificial intelligence, and robotic approaches to artificial life.

As the main advantage of μPADs is compact and low-cost, we suggest that three kinds of technology could be utilized to develop the prototype of μPADs-based instruments rapidly, including open source hardware-Aduino, smart phone and 3D printing.

Hardware Designs

Growth in open-source hardware designs combined with the decreasing cost of high-quality 3D printers have supported a resurgence of in-house custom lab equipment development. Herein, we describe a low-cost (< $400), open-source CO2 incubator. The system is comprised of a Raspberry Pi computer connected to a 3D printer controller board that has controls for a CO2 sensor, solenoid valve, heater, and thermistors. CO2 is supplied through the sublimation of dry ice stored inside a thermos to create a sustained 5% CO2 supply. The unit is controlled via G-Code commands sent by the Raspberry Pi to the controller board. In addition, we built a custom software application for remote control and used the open-source Grafana dashboard for remote monitoring. Our data show that we can maintain consistent CO2 and temperature levels for over three days without manual interruption. The results from our culture plates and real-time PCR indicate that our incubator performed equally well when compared to a much more expensive commercial CO2 incubator. We have also demonstrated that the antibiotic susceptibility assay can be performed in this low-cost CO2 incubator. Our work also indicates that the system can be connected to incubator chambers of various chamber volumes.
