Pengaruh variasi parameter cetak dan post process terhadap tingkat kekerasan spesimen hasil cetak tiga dimensi berbasis stereolithography (SLA)

Abstract: Abstrak. Keunggulan 3D printing stereolithography (SLA) dalam mencetak spesimen dengan geometri yang komplek dan kekasaran permukaan yang rendah menjadikan teknologi ini semakin banyak digunakan di berbagai bidang. Terlepas dari keunggulan yang dimiliki, sifat mekanis spesimen hasil cetak SLA yang rendah menjadi salah satu kekurangan utamanya. Dari beberapa penelitian telah dilakukan pengujian mekanis yang menunjukkan bahwa parameter cetak mempengaruhi sifat mekanis spesimen hasil cetak. Pada penelitian ini, p… Show more

“…4 shows the procedure used for the Shore D measurement of the sandwich specimen. The hardness tester was gripped on the drilling machine chuck to support the testing process while allowing the indenter to penetrate the specimen [24]. During the measurement, the indenter was held for 3 to 5 s until the hardness value was shown by the instrument.…”

“…The work of Lopes et al (2018) demonstrated that the combined polylactic-acid (PLA) and thermoplastic polyurethane (TPU) materials obtained from FFF possessed lower elastic modulus than that of the monolithic PLA but higher than that of the monolithic TPU [17]. Meanwhile, the study conducted by Arifvianto et al (2022) indicated that the Shore hardness value of 3D printed parts composed of PLA and TPU was lower than that of the monolithic PLA, but harder than that of the monolithic TPU [18]. On the other hand, the study conducted by Phattarateera et al (2019) showed that the tensile toughness of combined PLA and thermoplastic elastomer (TPE) was higher than that of the PLA/TPU [19].…”
