Pressure indicator pressure sensitive adhesive may contain microspheres that burst and release indicator when subjected to pressure and thereby produce a detectable indication of how much pressure has been applied when forming an adhesive joint between opposing structures. Electronic device structures can be assembled using the pressure indicator pressure sensitive adhesive. A camera or other sensor may monitor joint formation. The camera can gather infrared image data, visible light image data, or ultraviolet light image data. Sensor data such as magnetic or ultrasonic sensor data can also be collected on an adhesive joint. Joint inspection can be performed on test structures and production structures and corresponding adjustments made to the joint formation process. Positioners and other equipment that compresses the pressure indicator pressure sensitive adhesive can be adjusted in real time or calibrated using information about the condition of the pressure indicator pressure sensitive adhesive.

SYNTHESIS AND 3D PRINTING OF PHOTOCURABLE COLLOIDS

Photocurable colloid binders are provided that overcome deficiencies associated with 3D printing of high molecular weight polymers via VAT photopolymerization. Methods of additive manufacturing are also provided using the binders. The approaches described herein effectively decouple the viscosity-molecular weight relationship by synthesizing and processing photo-reactive aqueous colloids that are sequestered within a photocrosslinkable scaffold. Sequestering polymers within discrete internal phases prevents inter-particle entanglement of the polymer chains, thus ensuring low viscosity. VP of polymer colloids results in a solid green body embedded with high molecular weight polymer particles. A post-processing heated drying step allows the polymers to coalesce and further entangle, forming a semi-interpenetrating network with mechanical performance of the high molecular weight material. The resins can further include inorganic particles such as silica and other ceramics, metal particles, and the like. The coalescence can result in the particles being encapsulated in polymer, yielding unique hybrid materials with tunable properties. 1.

The composition according to claim 1 , wherein the matting agent is selected fromthermoplastic polymer matting agents such as hollow thermoplastic polymer microspheres or micronized polyolefin waxes; ormodified calcium carbonate matting agents such as core/shell particles comprising a calcium carbonate core and hydroxyapatite shell.3. The composition according to claim 1 , wherein the matting agent is an expanded hollow thermoplastic polymer microsphere claim 1 , preferably having a D50 particle size of from about 20 to about 30 μm.4. The composition according to claim 1 , wherein the matting agent is an unexpanded ...
