Abstract
Proses manufaktur dengan menggunakan metode 3D printing saat ini berkembang dengan sangat pesat. Material yang paling banyak digunakan dalam produksi menggunakan metode 3D Printer ini yaitu material polimer. Material polimer umumnya diproduksi dengan metode ekstrusi. Untuk pengaplikasian sebagai filament feed dalam proses 3D Printing, dilakukan proses ekstrusi menggunakan screw extruder untuk mendapatkan filament yang kontinyu. Dalam proses ekstrusi nya, ada beberapa kondisi ekstrusi yang harus dipenuhi. Seperti temperatur leleh, pembagian zona pada ekstruder, jenis screw, tekanan, shear rate dan feedrate.Untuk ekstrusi polimer dan komposit, desain dan konstruksi screw dan barrel merupakan pertimbangan penting yang menentukan kualitas hasil akhir produk ekstrusi sehingga untuk menjawab permasalahan tersebut, pada penelitian ini akan dilakukan perancangan mesin single screw extruder portable yang optimal untuk produksi filament 3D Printer. Dari hasil desain, didapatkan kapasitas produksi mesin sebesar 1.3 kg/jam dengan total energi listrik yang dibutuhkan sebesar 612 watt. Untuk proses produksi filament ABS digunakan temperatur 210 oC dengan putaran screw pada kecepatan 6,66 RPM. Hasil pengujian extrudat didapatkan diameter yang seragam sebesar 1,75 mm. hasil perhitungan production cost untuk produksi 1 kg filament yaitu Rp.11.776 sehingga dapat dikatakan lebih ekonomis jika dibandingkan dengan produk konvensional. ========== The manufacturing process using 3D printing method is currently
growing very rapidly. The most widely used material in production using this 3D Printer method is the polymer material. Polymeric materials are generally produced by extrusion methods. For application as filament feed in 3D Printing process, extrusion process is done using screw extruder to obtain continuous filament. In its extrusion process, there are some extrusion conditions that
must be noted. Such as melting temperature, zone classification on extruder, screw type, pressure, shear rate and feeding rate. For polymer and composite extrusion, the design and construction of screw and barrel is necessary to achieve the final product end
result for these conditions, in this research will be designed the optimal single screw extruder machine portable for 3D filament printer production. From the desig, obtained the production capacity of the machine of 1.3 kg / hour with the total electrical energy required for 612 watts. For the filament production
process. For ABS filament production process used temperature
210
o
C with rotation screw at speed 6.66 RPM. The extrudate test
results found a uniform diameter of 1.75 mm. the calculation of
production cost for the production of 1 kg filament that is
x
Rp.11.776 so it can be said more economical when compared with
conventional products.
