Gathering contributions by leading engineers and academicians in this area, it offers a valuable source of information for young scientists and research students."

"Proses additive manufacturing mendapatkan banyak perhatian dan berdampak besar pada teknologi manufaktur. Fused Deposition Modeling (FDM) merupakan salah satu teknologi additive manufacturing yang paling umum digunakan untuk memfabrikasi produk 3D print. Teknologi FDM dapat dengan cepat mencetak produk berbahan plastik maupun plastik komposit serta hanya membutuhkan sedikit energi dan biaya jika dibandingkan dengan teknologi additive manufacturing lainnya. Kekuatan mekanis dari produk hasil cetak FDM sangat berpengaruh dari paramaeter proses FDM itu sendiri. Untuk itu dilakukan studi optimasi parameter proses FDM. Sehingga dari parameter yang sesuai dapat meminimalisir cacat serta meningkatkan sifat mekanis dari produk. Pada penelitian ini material filamen yang digunakan adalah palstik komposit Polylactic Acid (50%Wt) + Steel (50%Wt) dan PolyAmide (75%Wt) + Carbon Fiber (25%Wt). Dengan variasi level parameter proses FDM pada temperatur nozel, kecepatan print dan arah orientasi print untuk menghasilkan spesimen uji tarik ASTM D638 TipeV. Spesimen tersebut selanjutnya dilakukan pengujian tarik dan porositas, untuk mengetahui sifat mekanis dari masing-masing material. Data hasil pengujian lalu dilakukan optimasi dengan metode VIKOR untuk mendapatkan parameter proses FDM terbaik. Hasil optimasi yang didapatkan dari penelitian ini adalah parameter proses terbaik untuk material PLA+Steel yaitu 0.1mm ketebalan lapisan, 220˚C temperatur nozel, 40mm/s kecepatan print, 90˚ orientasi print, 70˚C temperatur platform dan untuk material PA+CF yaitu 0.1mm ketebalan lapisan, 260˚C temperatur nozel, 40mm/s kecepatan print, 0˚ orientasi print, 85˚ temperatur platform.

"This book focuses on strengthening and joining materials by means of plastic deformation, gathering extended research papers presented at the AIMTDR 2016 conference. Plastic deformation is used in materials processing to improve the strength of the material. For example, the rod/screw used to connect the cooker handle to the main body has to be strong and sustainable; such rods can be strengthened by plastic deformation (using multi-stage forming operations etc.). Similarly, joining by means of plastic deformation is highly valuable since it avoids the material and environmental degradation often caused by fusion welding processes. The book discusses various processing techniques in which plastic deformation is used to strengthen materials – e.g. in equal channel angular extrusion, autofrettage etc., or to join materials without melting them – e.g. in friction stir processing, riveting etc. Offering an extensive guide, the book includes chapters on roll bonding, equal channel angular pressing, autofrettage, friction stir processing/welding, magnetic pulse welding, and riveting – processes used to strengthen and join a variety of materials for lightweight applications and sustainable manufacturing. The contents of this book will be useful to researchers and practitioners alike. "

"Proses alternatif dalam fabrikasi mikro yang telah ditemukan saat ini salah satunya adalah biomachining. Biomachining memiliki beberapa keunggulan diantaranya ramah lingkungan, tidak terjadi thermal damage pada permukaan benda kerja, dan efisien energi. Penelitian biomachining multi-axis sebelumnya yang menggunakan inklinator dengan satu sumbu rotasi dan dengan dua arah sudut inklinasi yang berbeda menunjukkan bahwa inklinasi benda kerja mempengaruhi bentuk profil permukaan hasil pemakanan material pada benda kerja. Dalam penelitian kali ini inklinator dikembangkan dengan menggunakan konsep sendi peluru pada meja kerjanya sehingga memiliki dua sumbu rotasi dan sudut inklinasi dapat dilakukan ke segala arah. Percobaan dilakukan dengan empat posisi inklinasi yang berbeda dan tiap - tiap posisi diberi sudut inklinasi 400. Terdapat dua jenis waktu percobaan, yaitu 6 jam dan 12 jam untuk tiap - tiap posisi inklinasi. Percobaan dilakukan dengan temperatur ruangan 23 - 25°C. Hasil pengukuran dari mesin SURFCOM menunjukkan bahwa pada bagian tengah permukaan hasil pemakanan material terbentuk Center Island dengan kedalaman undercut, sudut kemiringan undercut, dan nilai Ra yang berbeda - beda. Selain itu ditemukan bahwa perbedaan posisi kotak biomachining tidak memberikan pengaruh signifikan terhadap kedalaman undercut, panjang undercut, sudut kemiringan undercut, dan nilai Ra.

Alternative process in micro fabrication that has been found at this time one of them is biomachining. Biomachining has several advantages including environtmentally friendly, no thermal damage occurs on the surface of the workpiece, and energy efficient. Previous multi-axis biomachining research using inclinator with one axis of rotation and the angle of inclination in two different directions showed that the inclination of the workpiece affect the surface profile from material machining results at workpiece.

In this research inclinator developed using the concept of joint bullets on its work table so that it has two axes of rotation and the angle of inclination can be done in any direction. The experiments were performed with four different inclination position and each position given angle of inclination 400. There are two kinds of time experiments, which is 6 hours and 12 hours for each inclination position. The experiments were performed with room temperature 23-25°C.

Measurement result from the SURFCOM machine show that on the middle surface at material machining results formed Center Island with depth of undercut, tilt angle of undercut, and the Ra values are different each others. Moreover it was found that the difference in the position of the biomachining box no significant effect on depth of undercut, length of undercut, tilt angle of undercut, and the Ra values."
