4D manufacturing of intermetallic SMA fabricated by SLM process

4D Printing: Materials, Technologies, and Future Applications in the Biomedical Field

“…Current 3D applications for this technology include the printing of hearing aid shells. Its ability to print biomaterials indicates its potential to fabricate various personalised medical devices [35,40].…”

“…Selective Laser Melting (SLM) uses a laser to melt metallic powders in the same layer-by-layer process by inter-stage curing from a high-intensity laser beam [40]. This creates a homogeneous and dense 3D metallic structure removing the need for structural supports or binders [26].…”

“…This creates a homogeneous and dense 3D metallic structure removing the need for structural supports or binders [26]. The printing set-up is enclosed in a chamber as the reactivity of metallic compounds requires an inert atmosphere [40]. The 4D potential of this technology derives from the ability to fabricate both shape-memory alloys (SMAs) and single metallic smart materials [1].…”

“…The 4D potential of this technology derives from the ability to fabricate both shape-memory alloys (SMAs) and single metallic smart materials [1]. For example, Shishkovsky et al recently fabricated structures made from the shape memory alloys Ni-Ti (Nitinol) and Cu-Ni-Al using SLM [40]. set-up is enclosed in a chamber as the reactivity of metallic compounds requires an inert atmosphere [41].…”

Laser additive manufacturing of typical highly reflective materials—gold, silver and copper

“…对铜合金的打印研究则集中在锡青铜 [32][33][34][35][36][37][38] 、形 状记忆铜合金 [39][40][41][42][43][44][45] 、黄铜 [46] , 以及其他一些铜合 金 [47][48][49][50][51][52] . 表3总结了铜和铜合金的激光3D打印案例.…”
