[0051] [Preparation method of light-cured 3D printed linear polymer parts]
[0052] The present invention provides a preparation method for the above-mentioned light-cured 3D printed linear polymer parts, the preparation method comprising the following steps:
[0053] 1) blending at least one photosensitive resin monomer with a photoinitiator to obtain a resin solution;
[0054] 2) Optionally adding or not adding fillers to the solution to prepare a mixed dispersion;
[0055] 3) Perform photocuring 3D printing on the resin solution obtained in step 1) or the mixed dispersion obtained in step 2), to obtain the photocurable 3D printed linear polymer part.
[0056] Wherein, the monomers, photoinitiators and fillers of the photosensitive resin all have the meanings and mass ratios as described above.
[0057] According to the preparation method of the present invention, the preparation of the resin solution in step (1) and / or the mixed dispersion liquid in step (2) is carried ou...
Embodiment 1
[0096] 1) Blend 100 g of acryloyl morpholine with 0.5 g of camphorquinone, stir magnetically at room temperature for 30 minutes, and rotate at 600 rpm to obtain an acryloyl morpholine resin solution;
[0097] 2) The resin solution obtained in step 1) is subjected to light-curing 3D printing, the laser wavelength is 445nm, the thickness of each layer is controlled to 100 μm, and the curing time of each layer is controlled to 10s. After printing, a light-curing 3D printed linear polymer part can be obtained;
[0098]3) After the printed part obtained in step 2) was crushed (5g), it was added to acryloylmorpholine monomer (95g), and stirred at 80°C for 1 hour to obtain a recovered solution. The recovered The solution also contains acryloyl morpholine dissolved in the broken printed parts and acryloyl morpholine added when dissolving the printed parts; 4) Add 0.4g camphorquinone to the solution obtained in step 3), and stir magnetically at room temperature 30min, rotating speed 60...
Embodiment 2
[0104] 1) Blend 100 g of acryloyl morpholine, 0.5 g of camphorquinone and 5 g of liquid metal, and stir magnetically at 60°C for 30 minutes at a speed of 600 rpm to obtain acryloyl morpholine resin composite solution;
[0105] 2) The resin composite solution obtained in step 1) is subjected to light-curing 3D printing, the laser wavelength is 445nm, the thickness of each layer is controlled to 100 μm, and the curing time of each layer is controlled to 10s. After printing, a light-curing 3D printed linear polymer part can be obtained ;
[0106] 3) After the printed part obtained in step 2) was crushed (5g), it was added to acryloylmorpholine monomer (95g), and stirred at 80°C for 1h, and the obtained solution was added to the recovered solution At the same time, it contains acryloyl morpholine dissolved in the broken printed parts and acryloyl morpholine added when the printed parts are dissolved;
[0107] 4) Put the solution obtained in step 3) in a centrifuge, the centrifuga...
