The binder used by the ExOne3D printer head purchased from Germany is resol, the resol is pressed by compressed air to be sprayed onto the surface of the moulding sand layer through the nozzle during printing, the aperture of the nozzle is 0.2mm, the resin can be solidified and blocked in the nozzle hole after using the printer head for a long time, the resin has to be taken back by a supplier for maintenance, the use is influenced, the cost is increased, a potassium hydroxide solution is prepared by the prior art, the nozzle of the printer head is immersed and heated to a boiling state for no more than 10 minutes, the resin in the nozzle is completely dissolved, and the nozzle is recovered to be unblocked.)

1. The utility model provides a solution that ability clearance 3D printer beats printer head spout clearance jam, characterized by: heating saturated solution of potassium hydroxide in a container to boiling state, immersing the nozzle of the printing head in the solution, and completely dissolving the cured phenolic resin blocked in the pore of the nozzle in the process of less than 10 minutes, so that the nozzle is recovered smoothly.

Technical Field

Self-prepared solution for cleaning blockage of nozzle of printing head of 3D printer

Background

The 3D printer is a device which is imported from a drawing to a real object from German ExOne, utilizes a 3D technology to form in one step, is used for forming a casting sand mould, can reduce the period for manufacturing the mould, and quickens the progress of delivery by direct forming, but in the aspect of forming, the sand mould is formed by layering quartz sand and an adhesive, the adhesive is added into a printing head container of the 3D printer, compressed air is introduced to eject the adhesive from a nozzle layer by layer, the nozzle is of a strip-shaped air hole (the aperture is 0.2mm), and after the adhesive is used, the residual adhesive can be gradually hardened along with the time extension to block the nozzle. If the 3D printer is used continuously, the adhesive does not stay, the nozzle blockage phenomenon cannot occur, and the nozzle blockage phenomenon can occur only when the interval time of use is slightly long and the adhesive is solidified.

When the nozzle blockage phenomenon occurs, cleaning is carried out by ethanol according to the specification, the cleaning failure is found, the cleaning failure is related to a supplier agent, a specially-assigned person at the agent comes to the site to replace the printing head, the blocked printing head is brought back to the site to be processed, when the cleaning failure occurs, the agent is firstly related to the agent, the time is arranged at the agent to determine the site service, and the 3D printer cannot be used at the moment and can be used again after a coming person replaces the printing head.

Disclosure of Invention

The invention aims to solve the problem that when a nozzle of a printing head of a 3D printer is blocked, the nozzle can be maintained and cleaned by self, and the blocked nozzle is recovered to be smooth by adopting a simpler and more convenient method.

The technical scheme is that a saturated potassium hydroxide solution is prepared in advance, then a blocked nozzle is immersed in an open container filled with the saturated potassium hydroxide solution, the solution is heated to a boiling state, and resin of the nozzle is completely dissolved in the solution in about 10 minutes and then is recovered to be smooth.

The invention has the obvious effects that the blocked nozzle is not needed to be detached again and handed to a supplier to replace the nozzle, but the solution is prepared by self, and the problem of nozzle blockage can be solved only by taking 10 minutes, thereby reducing the waiting time and saving the cost.

Detailed Description

The nozzle 2 of the printing head 1 is immersed in a container 3 containing a potassium hydroxide saturated solution 4, and the potassium hydroxide solution 4 is heated to dissolve the resin in the pores of the nozzle 2.
