Description

3D printing consumable welding machine

Technical Field

The utility model relates to the technical field of 3D printing consumable welding, in particular to a 3D printing consumable welding machine.

Background

As 3D printing technology matures, 3D printers are also common products in human life, and as with ordinary printers, 3D printers are also one of the indispensable tools in life work. However, unlike the conventional printer, most 3D printers in actual use are FDM type, and the consumable material used is polylactic acid, i.e., PLA. When in use, the silk-shaped PLA material is melted into a liquid state through a high-temperature nozzle of the 3D printer and is re-solidified into a target shape. However, in practical use, the wire-shaped PLA consumable material may cause unexpected material breakage due to temperature, printing speed or other uncontrollable factors, and even if no material breakage occurs, it is often encountered that a roll of PLA consumable material is used mostly, a new model is desired to be printed, the remaining material is insufficient, and a short consumable material is discarded, so that waste is caused by reusing a roll of new PLA printing consumable material. In order to solve the problem of insufficient material breakage or surplus material, unused consumables and new consumables need to be spliced, so that the problem of insufficient material breakage or consumables can be solved.

It is known through investigation that the diameter of PLA and ABS linear consumable materials commonly used in the market is 1.75mm, the length of 1 kilogram of PLA consumable material is about 340 meters, and the length of 1 kilogram of ABS consumable material is about 400 meters. Taking most of the PLA consumables used in the market as an example, the consumables of one meter are about 3g. Because the consumable materials required by printing of different models are different in size, the consumable materials required by most models are more than hundred grams (the consumable materials consume more than 30 meters), that is, if the residual length of one roll of consumable materials is less than 30 meters, most printing requirements cannot be met, the consumable materials cannot be directly used, and if the consumable materials are not utilized, a large amount of material waste can be caused.

At present, the welding of 3D printing consumables is usually in breakpoint department, inserts new consumptive material into the nozzle, melts the consumptive material through the nozzle to weld two sections consumptive material, but this kind of method needs the 3D printer to stop going on after working, can influence printing efficiency, and the welding effect is relatively poor.

Inspired by the optical fiber fusion splicer, the problem that linear 3D consumptive material lacks the continuity can be solved to a certain extent to 3D consumptive material fusion splicer, and its principle is similar with the optical fiber fusion splicer, and specific fusion process is roughly divided into three, at first, melts disconnected 3D printing consumptive material both ends, splices the consumable of melting again, and at last with melting part plastic to the diameter of standard.
