Problems solved by technology

The biggest disadvantage of ABS is that it is easy to shrink and become brittle, and it is also relatively easy to warp. On the other hand, the steps of ABS filament after printing are a bit difficult.
Since this material has the characteristic of shrinking when it is cold, it will partially fall off from the heating plate and hang in the air, causing problems
In addition, if the height of the printed object is very high, sometimes the whole layer will be peeled off
Therefore, ABS materials often cannot be used alone as 3D printing consumables. It is an urgent problem to develop an ABS-based composite material that can eliminate the warpage and brittleness of ABS in the 3D printing process as 3D printing consumables.

Abstract

The invention discloses an ABS (Acrylonitrile Butadiene Styrene)-based nanocomposite for 3D (Three-dimensional) printing. The nanocomposite is prepared from the following components in parts by weight: 54 to 60 parts of ABS, 4.8 to 9 parts of TPU (Thermoplastic Polyurethane), 4 to 8 parts of modified nanometer silicon dioxide master batch, 0.5 to 0.7 part of plasticizer, 2 to 4 parts of solubilizing agent and 0.5 to 0.7 part of antioxidant. The preparation method comprises three steps: I, performing surface treatment on nanometer silicon dioxide; II, preparing first-grade master batch from the modified nanometer silicon dioxide and ABS particles; III, mixing the first-grade master batch, the ABS, the TPU, the plasticizer, the solubilizing agent and the antioxidant, and adding the mixture into a double-screw extruder for extruding and granulating to obtain the ABS-based nanocomposite.
