Embodiment 1

[0044] In terms of mass fraction, 85% of dimethylacetamide, 10% of ethyl acetate and 5% of methyl ethyl ketone are selected to form a mixed solvent liquid, and the TPU object is soaked in the surface liquid for 1 minute. The surface changes of TPU objects: the dissolution is faster, the surface can form a film, and the solvent removal process is slower.

Embodiment 2

[0046] In terms of mass fraction, 70% of dimethylacetamide, 20% of ethyl acetate and 10% of methyl ethyl ketone are selected to form a mixed solvent liquid, and the TPU object is soaked in the surface liquid for 55s. Surface change of TPU objects: Moderate surface change speed, convenient manipulation, fast film forming speed, and excellent air tightness.

Embodiment 3

[0048] In terms of mass fraction, 60% of dimethylacetamide, 30% of ethyl acetate and 10% of methyl ethyl ketone are selected to form a mixed solvent liquid, and the TPU object is soaked in the surface liquid for 55s. Surface changes of TPU objects: the surface treatment speed is slow, and the airtightness of the objects is good.

Abstract

The invention discloses a pneumatic driving robot multi-fingered dexterous hand manufacturing technique based on 3D printing. The manufacturing technique comprises but not limited to the following steps that (1) a pneumatic driving robot multi-fingered dexterous hand part is obtained through the 3D printing technique; and (2) liquid surface treatment is conducted on the 3D-printed part, the 3D-printed part can be dissolved or partially dissolved in a solution, and the solution and water can be mutually dissolved. In this way, pores of the 3D-printed part are eliminated, the airtightness of the3D-printed part is improved, the 3D printing technique can be used for manufacturing a pneumatic driving robot multi-fingered dexterous hand, the design work of robot hands is facilitated, unidirectional or multidirectional or combined complex robot multi-fingered dexterous hands can be manufactured, and the manufacturing technique is particularly suitable for intelligent flexible robot development work.

Description

technical field [0001] The invention belongs to the technical field of robot multi-fingered dexterous hand manufacturing, and in particular relates to a manufacturing process of a robot multi-fingered dexterous hand (Robot Multi-fingered Dexterous Hand) based on a 3D printing pneumatic drive mode. Background technique [0002] 3D printing, also known as additive manufacturing, is an advanced manufacturing method based on the principle of layer-by-layer material accumulation that has emerged and developed rapidly in the past 30 years. According to the definition of ASTM Committee F42, 3D printing includes a total of 7 sub-technologies: Material Extrusion, Material Jetting, Binder Jetting, Container Type Vat Photopolymerization, Sheet Lamination, Powder Bed Fusion, Directed Energy Fusion. Among them, material extrusion, container photopolymerization and powder bed fusion technology are the most widely used. In particular, material extrusion 3D printing has been widely used i...
