Embodiment

[0045] (1) It is planned to print an ABS material with a bottom size of 400mm*400mm;

[0046] (2) Make a rectangular wooden container of 450mm*450mm*5mm (length, width and height) using Auspine board;

[0047] (3) Brush the inner bottom surface of the wooden container with an iron brush to roughen it;

[0048] (4) Clean up the sawdust and dust inside the wooden container 1 with a vacuum cleaner;

[0049] (5) Pour the white latex into the wooden container, and pour the white latex three times. The thickness of each pour is between 1-1.5mm. After each pour, let it stand until the first layer is poured. After the white latex is cured, pour the second layer. After the second layer hardens, pour the third layer. Smooth the surface of the top layer of latex to ensure that the upper surface of the white latex is about 1-1.5mm away from the upper edge of the wooden container. ;

[0050] (6) Evenly lay the dried ABS particles (3mm cylindrical material) on the surface of the flexible...

Abstract

The invention discloses a large-size anti-warping 3D printing flexible bottom plate with an easy-to-take part and a using method thereof. According to the printing bottom plate, a cured flexible colloid is loaded in a container, printing material particles are laid on the surface of the cured flexible colloid, and an additive manufacturing process is carried out on the printing material particles.The whole printing bottom plate does not need to be heated, so that energy conservation and environmental protection are achieved; the surface material of the bottom plate and the printing material are the same material, and the surface particles and the surface material in a molten state have a good bonding effect; after printing is completed, the part is convenient to take; the base plate can be repeatedly repaired and used, and the cost is low; the shape of the base plate can be changed along with the shape of a workpiece 4, so that material waste is avoided to the maximum extent; the bottom plate is formed by compounding a plurality of materials, and the surface material of the bottom plate is a raw material consistent with the printing material so as to meet the requirements of materials with different printing temperatures; and the flexible bottom plate is beneficial to release of internal stress in the printing process, and cracking caused by stress concentration can be effectively prevented.

Description

【Technical field】 [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing flexible bottom plate for large-size anti-warping and easy-to-take parts and a use method thereof. 【Background technique】 [0002] Fused deposition modeling (FDM) is a widely used polymer 3D printing technology. In this additive manufacturing technology, the plastic polymer is heated and melted to accumulate and adhere to the predetermined printing position in the form of melt, and the printed product is finally formed by stacking and bonding layer by layer of the melt. [0003] In this process, shrinkage and deformation will occur during the cooling and hardening of the polymer. Due to the different temperatures and uneven shapes of various parts during the printing process, the resulting shrinkage and deformation are asynchronous and uneven. When the shrinkage and deformation inside the printed part When it is greater than the bonding force betw...
