effects of scan direction and orientation on mechanical properties of laser sintered polyamide-12
in order to understand the impact of layer-wise scanning direction in the selective laser sintering process, test coupons were manufactured for mechanical testing from duraform™ polyamide powder. the effects of laser energy density, varying between 0.003 and 0.024 j/mm 2 were examined in test specimens rotated 90º through the z axis. sls machines do not always facilitate ‘cross-hatching’ of lay...
متن کاملLong-term Properties of Laser Sintered Parts of Polyamide 12 - Influence of Storage Time and Temperature on the Aging Behavior
The key in selective laser sintering (SLS) of polyamide 12 for exceeding the cusp from a prototyping to a serial production technique poses the long-term behavior of such components. The improvement of additive manufacturing technologies is attended by the enlargement of the possible ranges of use. The crucial obstacle for their actual use is the ignorance of the long-term properties and the co...
متن کاملSintering Study of Polyamide 12 Particles for Selective Laser Melting
Selective Laser Melting is an additive manufacturing technique, using a laser to promote the fusion followed by the solidification of a powder bed into a component. One of the most interesting topics about this process is the coalescence behavior of particles taking place in the powder bed during exposure. The coalescence of particles has been investigated in different fields of materials. Poly...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولDoes Steam Autoclaving Affect the Accuracy of Implant Impression Systems?
The purpose: The aim of this in-vitro pilot study was to evaluate the effect of steam autoclaving of the implant analog and impression coping on the accuracy of impression procedure. Materials and methods: A master casts model was constructed, with a pair of commercially available fixtures. Ten pairs of impression copings were used to make the impression. Implant analogs were then attached to t...
