A computerized addictive aided design based on manufacturing system that is digitally integrated, has been modified, built, and designed. The system refers to the smart manufacturing sectoral (smart manufacturing) which to answer the challenges of industrial revolution 4.0, namely the purpose for efficiency of the distance, cost efficiency, time efficiency, quality improvement and increased flexibility. The concept of manufacturing systems with fused deposition modelling 3D printers integrated with the internet or intranet has been modified, for the purpose to connected each other under one platform being namely as category as a Computer Aided Manufacture (CAM) system. A synthesis between the production room and the customer, real-time depiction of 3D CAD users can be presented and connected directly to the manufacturing locations where the desired product is located. Seeing this as an opportunity growing for the industrial society, the author conducted research to modified and collaborate the system. The method used in this study was carried out with rapid application design or better known as Rapid Application Development/RAD aimed at simplifying and accelerating the design of the system for 3D print web application system. CAD drawings can be processed from the user’s device to the main webserver and then forwarded into the operator’s production system space, resulting in a final product/finished goods, with no restrictions on distance, area and allows low production costs (low production costs). The results of this study represent the manufacturing industrial that is being supported by the application of information technology, where are manufacturing is connected with IoT (Internet of Things). Presenting the benefits of the Industry 4.0 concept. The customization system to be able to add value added for the competitiveness small and medium companies in Indonesia on manufacturing process and can support micro economic growth.

Generally, a maintenance process of a machine tool is oriented to maintain its reliability and availability in a relation of its productivity. This productivity will make a direct impact on the economic aspect of its plant. Ecomaintenance is a maintenance concept which sees maintenance in a different perspective. There is another effect on a machine that is maintained well on the environmental aspect beside its benefit of technology and economic aspects. If a machine is maintained with a proper maintenance, it will have a performance suitable with its age design condition. A machine with a good maintenance generally has a minimum rate of pollutant and waste which is possible emerging from the machining process. Then, if it uses for a machining process, it will produce a good quality product on its surface roughness and dimension accuracy. The electrical energy consumption of the machine also can be saved. It means that the GHG which usually emerges from the process of electrical energy generation in the power plant can be minimized, also the coal as fuel can be saved. The result of experiment has proven that the machine with bad maintenance will consume the electrical power higher in range 10%-60.81% than the machine with a good maintenance.

Rapid prototyping adalah metode untuk membuat suatu model (prototipe) sebuah produk secara cepat menggunakan teknologi layer by layer. Salah satu dari metode rapid prototyping adalah Fused Deposition Modelling atau sering disebut FDM. Sebuah mesin rapid prototyping yang awalnya single extruder dengan sistem direct extruder akan diubah menjadi dual extruder dengan bowden extruder. Perubahan jumlah extruder ini akan disertai beberapa penambahan parts dan penyesuaian desain baik konstruksi rangka mesinnya, pemegang extruder serta perintah/kontrol gerakan. Penambahan beberapa parts ke bagian extruder kemungkinan akan menyebabkan perubahan posisi meja sehingga harus dilakukan leveling heatbed pada mesin hasil modifikasi. Selanjutnya dibuat benda uji untuk mengetahui ketepatan dimensinya dan kekasaran permukaan. Pada proses pembuatan benda uji digunakan layer height yang berbeda yaitu 0.2 mm, 0.3 mm, 0.4 mm. Benda uji dengan layer height 0.3 mm mempunyai ketelitian dimensi yang paling baik dengan penyimpangan maksimal 0.1 mm

Mesin 3D printer adalah mesin pembuat suatu model 3D. Metode mesin 3D printer yang digunakan pada Fakultas Teknologi Industri Universitas Trisakti adalah metode FDM (Fused Deposition Modelling). Diketahui adanya ketidak stabilan pada meja cetakan mesin 3D printer pada saat proses produksi dilakukan. Ketidak stabilan meja cetakan mesin 3D printer, menyebabkan tidak maksimalnya produk yang dihasilkan. Terdapat perbedaan antara hasil produk dengan bentuk produk yang telah di desain sebelumnya. Setelah diteliti lebih lanjut, ketidak rataan pada meja disebabkan pada pengaturan meja cetakan yang kurang sesuai. Hasil dari redesain dapat menstabilkan meja cetakan dan memudahkan untuk melakukan kalibrasi dan pengaturan pada meja cetakan mesin 3D printer. Hal ini terbukti ketelitian dimensi produk hasil cetakan yang meningkat dari penyimpangan terbesar 0,037 mm menjadi 0,069 mm, yang diukur dengan proyektor profil yang mempunyai kecermatan 1 mikrometer. 3D Printer Machine is a 3D shaped model making machine. The method of 3D printer machine used by the faculty OF Industrial Technology of Trisakti University is FDM (Fused Deposition Modelling) method. There is known unevenness on the build plate of 3D printer machines during the production process. The unevenness that appears on the objects makes the build plate used by the 3D printer engine unstable. This causes the product to be produced not maximal. There is a difference in shape between product results and previous product design. After further investigation, the unevenness of the table was caused by the improper arrangement of the printed table. The results of the redesign will stabilize the print table and make it easier to calibrate and adjust the print table of the 3D printer machine. This proven that precision of product dimension increase from 0,037 mm deviation to 0,004 mm, its measured with a profile projector has 1 micrometer resolution.
