Abstract

Plastic waste damages the environment because it is not easily broken down by nature. It needs special processing of plastic waste but still does not cause environmental pollution. Thermal degradation technology is able to degrade plastic waste and turn it into useful alternative fuels. The results of this processing technology are liquid, gas and solid products. The tools used in this treatment are LPG heaters, thermal degradation furnaces and water-cooled condensers. The design capacity of this tool is 4 kg of plastic waste for one production with an operating temperature of ± 300 ° C with a processing duration of ± 120 minutes. The demand for LPG as heating is planned at ± 0.23 - 2.7 kg / hour. The materials are made of steel plates with a 3 mm thickness . The dimensions of the condenser pipe are designed to be ± 0.9 m long with a planned intake water temperature of 25 ° C.

Abstract

3D printing machine is a devie that can produce wide various kind of product. The simplicity of the 3D printing machine makes he 3D printing machine can be applied in various kind of application. But the product that produce using 3D printing machine may have some defect in mechanical properties likes in another mehods. Because of that reason, there is needs to improve the process of 3D printing. One of the mehod tha can be used is to improve the parameters in the printer like the type of printer, capacity of the printer, he software that used to processes the product, variation of travel speed, the number of layer, the thickness of product, and the temperature that used in the printing processes. Based on the observation the researcher had been done in the processes in 3D printing processes the temperature of extruder of 225oC and 60oC of heat bed can produce the highest tensile strength. The value of the highest tensile strength is 34 N/mm2. From these can be concluded that the best variation of temperature of extruder and heat bed is 225 oC and 70 oC.
