3D general photocurabel model of resin with various kinds of microparticles

Abstract

We have constructed world-first generalized model for expecting 3D curing characteristics of photocurable polymer including micro particles. First, our theory is applicable for all polymers that respond to light. Second, we can adapt all kinds of particles to our theory. Moreover, the complicated calculation is not necessary. We can expect 3D curing properties through characteristics of resin and microparticles. Therefore, our theory is useful for developing newly photocurable polymer not only with microparticles, but also without microparticles. We believe that our model becomes fundamental theory for the 2D and 3D microfabrication in the photolithography and microstereolithography.

Alleviating Distortion and Improving the Young’s Modulus in Two-Photon Polymerization Fabrications

“…As the raw material it uses is liquid resin, the properties of the resulting printed structure can easily be modulated by adding other ingredients. For example, magnetic [1,2,3,4] or conductive [5,6,7] particles may be added to the resin to make the resulting structure ferromagnetic or electrically conductive. Moreover, reinforcing agents may be added to produce a composite material.…”

Fabrication and Compressive Behavior of a Micro-Lattice Composite by High Resolution DLP Stereolithography

“…In vat polymerization, such structures are often not necessary as support can be provided through flotation by the liquid resin; (3) the properties of the resulting printed structure can easily be modulated by adding reinforcing agents or other ingredients into the resin to produce a composite material [ 40 ]. For example, the material may be made ferromagnetically or electrically conductive by adding magnetic [ 41 , 42 , 43 ] or conductive [ 40 , 44 , 45 , 46 ] particles to the resin; (4) further properties modulation can be achieved by using the printed polymer structure as a template to produce lattice made of metallized polymeric composites [ 47 ], metal or ceramic hollow tubes or solid ceramic lattice [ 48 , 49 , 50 ]. Metallization of the surface of a polymeric lattice increased its stiffness and strength [ 47 ].…”
