Abstract

The invention discloses a light curing 3D printing device and printing method using light curing materials as raw materials. The printing device comprises a container groove, a developing module, a working bearing table, a screw rod, a lifting machine and a light source; the developing module is arranged at the bottom of the container groove, and the developing module and the container groove are fixedly arranged together. The printing method comprises the following steps that firstly, liquid-state photosensitive resin is injected into the container groove; secondly, a shape required to be printed is input to the developing module through a computer; thirdly, according to the thickness required to be printed, the position of the working bearing table is adjusted through a screw rod; fourthly, light emitted by the light source passes through the developing module, at the moment, the developing module carries out local blocking on the light projected by the light source, the unblocked photosensitive resin is in contact with the light, and the resin is converted into the solid state from the liquid state; fifthly, the screw rod on the working bearing table obtains power through a lifting motor to move upwards; and sixthly, the step two to the step four are repeated until a printing layer face is manufactured.

Description

A kind of photocuring 3D printing equipment and Method of printing thereof

Technical field

The invention belongs to printing field, particularly relate to simple, the easy to operate photocuring 3D printing equipment of a kind of mechanism and Method of printing thereof.

Background technology

Existing photocuring technology is the photopolymerization principle work based on liquid photosensitive resin, first photosensitive resin is injected in solidification groove, then laser beam is brilliant in solidifying the top of groove from top to bottom in the enterprising line scanning of photosensitive resin by deflection optical, the track of scanning and the presence or absence of light all have computer to control, the place that luminous point is got to, it is solid-state that photosensitive resin runs into light by liquid state, then the cushion cap that works declines a layer height, carry out the scanning of next aspect again, repetition like this, until whole workpiece manufactures complete, obtains a 3D solid workpiece.

The shortcoming of above-mentioned technology is: use light beam to scan the liquid level in solidification tank liquid, this is high to liquid level flatness requirement, complete machine needs strictly to control resonance, prevent liquid level irregular, therefore expensive equipment is needed to ensure the stable of liquid level, and its projection need coordinate optical mirror slip just can complete by optical instrument, production process is complicated, cost intensive.

Summary of the invention

For addressing the aforementioned drawbacks, the invention provides a kind of photocuring 3D printing equipment and Method of printing thereof, the exposure that the present invention carries out from bottom to top by distinctive structural design to photo-curing material, without the need to carrying out precise and stable control to liquid level, thus avoid the costliness required for stable liquid level to pay, and structure of the present invention is simple, easy to operate, low cost.

For achieving the above object, the invention provides a kind of employing photo-curing material is raw-material photocuring 3D printing equipment and Method of printing thereof, its printing equipment comprises: container slot, visualization module, work cushion cap, screw rod and lift, light source, and described visualization module is positioned at the bottom of container slot and container slot is fixedly installed togather.

As preferably, the preferred full impregnated liquid crystal display of described visualization module, full impregnated liquid crystal display is connected with computer, and controls the image of required display by computer.

As preferably, described work cushion cap is connected with screw rod, and screw rod obtains power thus the work of drive cushion cap moves up and down in container slot from lifting motor.

As preferably, the bottom surface of described work cushion cap is provided with grabs adsorption device, and the length of work cushion cap and width are less than length and the width of container slot.

As preferably, the grabbing symbol device on described work cushion cap bottom surface preferably grabs attached hole or wave groove.

As preferably, the preferred liquid photosensitive resin of described photo-curing material.

As preferably, described light source is positioned at the lower position of visualization module, the irradiation that light of its injection carries out from bottom to top through visualization module to the photo-curing material in container slot.

The invention has the beneficial effects as follows: described light source is positioned at the lower position of container slot, by irradiating the visualization module bottom container slot, realization carries out irradiation from bottom to top to the photo-curing material in container slot, thus make irradiated photo-curing material be solid-state by liquid conversion, the advantage of this kind of device is that light projects from bottom to top, liquid level lower in groove is exposed, thus without the need to controlling the stability of liquid photocurable material in container slot, and the present invention is without the need to expensive optical instrument, three-dimensional shape can be printed, and then minimizing cost, reach efficient, of fine quality, inexpensive effect.

For fully realizing effect of this printing equipment, a kind of 3D Method of printing being now provided, comprising following steps.

Step one, is injected into liquid photosensitive resin in container slot.

Step 2, by the shape of required printing by computer input to visualization module, especially it should be noted that and the shape of required printing is set to printing opacity, the surrounding of required printing shape is set to light tight without the need to the part printed.

Step 3, according to the thickness of the required printing position by screw rod adjustment work cushion cap.

Step 4, the light penetrated by light source invests visualization module, to the part needing to print, light can be irradiated on photosensitive resin through visualization module, to not needing the partial development module printed can block light, the photosensitive resin contact light be not blocked, becomes solid-state by liquid state, and be set on the bottom surface of work cushion cap, be blocked not with the photosensitive resin of light contacts still for liquid.

Step 5, the screw rod on work cushion cap obtains power by lifting motor and moves up.

Step 6, repeats step 2 to step 4 and carries out the solidification printing of next aspect until structure at all levels manufactures complete, obtain a 3D solid.

The invention has the beneficial effects as follows, make full use of the structural advantage of printing equipment, make Method of printing very simple and easily operate, the solid figure accuracy of making is high.
