Become approximate gel, workpiece is wrapped.Raw material used by 3D printing as be used as photo-curing polyurethane resin or
The resin or oligomer of the other high functionalities of person are that high viscosity is difficult to flow at normal temperatures, when being heated to certain temperature
Its viscosity is greatly lowered afterwards, can restore high viscosity again again after being re-cooled to room temperature, i.e., approximate gel.
Determine that workpiece puts orientation relative to print platform before carrying out 3D printing operation；By model along print platform
If short transverse is successively divided into dry chip, the sectional view of every layer of slice is obtained.
When carrying out 3D printing, the photosensitive resin layer is laid on print platform；The thickness of each photosensitive resin layer
It is identical as the corresponding thickness of slice, and cross section is more than corresponding be sliced；Every layer heated by photosensitive resin layer after be laid with, use
Curing light source carries out curing process, and the shape size that curing light source is irradiated is consistent with corresponding serial section；When solidification is completed,
With the reduction of temperature, uncured photosensitive resin is changed into approximate gel.
After every layer of photosensitive resin completes photocuring, mobile print platform or curing light source make curing light source to photosensitive resin
The distance at layer top is always kept in a fixed state value.
The photosensitive resin is arranged by the way of spraying on print platform after the heating.
After the completion of spraying, photosensitive resin layer upper surface is scratched using scraper plate.
After the completion of printing, the workpiece wrapped up by approximate gel photosensitive resin is obtained, by workpiece and approximate gelatinous resin
Heating is recycled the heated photosensitive resin for being changed into liquid, and is cleaned to workpiece.
Several layers of photosensitive resin are first laid on print platform before printing workpiece, wait for that its cooling transformation is approximate gel
It is used as place mat after state, the operation of printing workpiece is then carried out on the place mat.
As shown in the flow chart of attached drawing 1, this method can be summarized as following steps：
Step 1 imports the model file of workpiece in corresponding software, adjusts the pendulum for determining model relative to print platform
Put orientation；If the short transverse by model along print platform is successively divided into dry chip, the sectional view of every layer of slice is obtained；
Reduce workpiece as possible when workpiece is put puts height to reduce the laying number of plies of resin, to reduce printing step
Suddenly, printing effect is improved；Meanwhile because the precision of light source irradiation image determines the printing precision of horizontal direction, and photosensitive tree
The thickness of lipid layer determines the printing precision of short transverse, so when the machining accuracy difference of both direction, is put in design
Detail section can be placed in orientation with high accuracy and be completed when orientation, so that it is guaranteed that the workpiece quality printed is best.
Photosensitive resin layer is laid on print platform by step 2 using spraying equipment, and the spraying effect depending on resin is selected
Scraper plate carries out blade coating in photosensitive resin layer upper surface keeps its holding smooth, to improve printing precision；Each photosensitive resin
