“…Penelitian terkait mesin 3D Printing dilakukan Tontowi et al (2017) untuk mencari komposisi optimal melalui material polymethylmethacrylate (PMMA), hydroxyapatite (HA), dan sericin. Rasio komposisi dari powder PMMA:liquid MMA yaitu sebesar 2 : 1.8, konsentrasi hydroxyapatite (HA) sebesar 10% dari powder PMMA dan sericin sebesar 0.32% dari hydroxyapatite (HA).…”

This research uses material polymethylmethacrylate (PMMA) and hydroxyapatite (HA). The composition of PMMA: MMA is 1: 1 with the ratio composition of HA to PMMA powder is 0.50: 1 (w/w). The composition will be printed with a 3D Bioprinter that has 1.5 mm nozzle. The parameters of the 3D Bioprinter`s tested are perimeter speed with a range of 20 mm/s, 30 mm/s and 40 mm/s, infill speed with a range of 50 mm/s, 60 mm/s, and 70 mm/s, and fill density with a range of 40 mm/s, 50 mm/s and 60 mm/s. These parameters were optimized using response surface method with Minitab software 17. The design of specimens to be printed with a 3D Bioprinter machine using ASTM D638 Type 1. This design will be tested with dimensional measurement and tensile strength. The result of this study is indicated the optimal point at 31.15 mm/s for the perimeter speed`s parameter, 58.84 mm/s for the infill speed`s parameter and 64% for the fill density`s parameter. Dimension of the design is added with a scale of 1: 1.02 mm for length`s dimensions, 1: 1.08 mm for width`s dimensions, 1: 1.09 mm for narrow width`s dimensions and 1: 1.17 mm for thick`s dimensions.

“…This specimen was chosen because of its simple shape. The materials used are PMMA heat curing and hydroxyapatite as in Tontowi et al (2017). In this study hydroxyapatite is used up to 25% of PMMA powder, but in this study the composition of hydroxyapatite will be increased up to 50% of PMMA powder.…”

Bone fracture caused by various incident causes medical problems. Then bone restoration is required. Bone grafts can be used to solve this problem. One of the materials that can be used to produce bone graft is PMMA. PMMA requires to be combined with other materials to extend the solidification time. The material that can be used for bone graft material is sago starch. The main ingredient composition of Biocomposite [sago/PMMA] consists of sago: PMMA = 1 : 1 (w/w). The composition of the addition of MMA is 10% (v/w) of PMMA, this is to extend the curing time. Thus the material can be through from the chamber extruder to the nozzle. This research aims to obtain combinations of 3D Printer FDM Customized machine parameters for minimizing of error dimension. The 3D Printer machine uses pneumatic system to push the material from the container to the chamber and used screw extruder to push the material out through the nozzle. The experimental design method used a 2 k fractional factorial design, with 3 parameters, 2 levels and 3 responses. The experimental results obtained that the layer height parameter has a significant influence on the x-dimensional error. The optimization results obtained a combination of parameters to get the smallest error dimensions, the print speed is 25 mm/s, the layer height is 2.93 mm and the fill density is 20%. The results of optimization obtained that the x-dimensional error is 0.016, the ydimensional error is 0.069 and the z-dimensional error is 0.4539.
