Researchers propose 3D printing of high-performance elastomers through vat photopolymerization

Acrylate-based ultraviolet (UV)-curable resins are currently used as raw materials to obtain desired performance by adjusting the types and ratios of oligomer and reactive monomers in the resin system. However, due to low degree of free-radical polymerization, the elastomers prepared by vat photopolymerization (VPP) technology show low strength, poor resilience, and unsatisfactory mechanical properties. In a study published in Advanced Materials , the research group led by Prof. Wu Lixin from Fujian Institute of Research on the Structure of Matter of the Chinese Academy of Sciences proposed 3D printing of high-performance elastomers through vat photopolymerization. The researchers analyzed the structure-property relationship between molecular weight and mechanical properties, and selected polytetramethylene ether glycols (PTMGs) with different molecular weights (Mn=1000, 2000, 3000 g mol-1, respectively) as reactants to react with isophorone diisocyanate (IPDI). The obtained polyurethane blocked oligomers (PUBs) exhibited high viscosities.

You know that stuff at the dentist's office that hardens when you add light to it? That's a whole class of reaction called photopolymerization and they use to 3D print ceramics. The polymers form a matrix around the clay particles, so when you lock in the matrix by cross-linking (fusing the polymers*), the clay is instantly hard, no heat needed.

Enhancing Radical-Mediated Photopylomerization Efficacy and Crosslink Depth: Kinetic Modeling of a Two-Monomer System

Enhancing Radical-Mediated Photopylomerization Efficacy and Crosslink Depth: Kinetic Modeling of a Two-Monomer System- Crimson Publishers

The kinetics and rate equations are derived to analyze the enhanced cross-linking via a two-monomer system, in which the photoinitiator (PI) triplet excited state interacts with monomers, [A] and [B], to form reactive intermediates radicals, which could interact with oxygen, [A],[B], and bimolecular termination. Quasi-steady-state conditions are employed to solve for radicals which are used to find the temporal prpfiles of the monomer efficacy and cosslink depth, as a function of light intensity, exposure time, and concentrations of PI, [A] and [B]. Higher light intensity and radical coupling rate constant lead to faster depletion of PI and oxygen concentration; and faster transient rising efficacy, but a lower steadystate efficacy. Conversion efficacy is an increasing function of the ratio [B]/[A]. In contrast, efficacy is a decreasing function of the reaction rate ratio of oxygen and triplet state, resulted by the stronger oxygen inhibition. Efficacy may be improved by additive enhancer-monomer or extended lifetime of photosensitizer triplet-state or oxygen singlet, in consistent with the measured clinical data. Oxygen inhibition effect may be reduced by the presence of D2O, which extends the lifetime of singlet oxygen. Our analytic formulas provide useful guidance for the scaling laws for further clinical studies.

Swift 4-D printing with shape-memory polymers

Shape-memory polymers or shape-shifting materials are smart materials that have gained significant attention within materials science and biomedical engineering in recent years to build smart structures and devices. Digital light processing is a vat photopolymerization–based method with significantly faster technology to print a complete layer in a single step to create smart materials. Fahad Alam and a team of scientists in electrical and computer engineering, and nuclear engineering at the King Abdullah University of Science and Technology, Saudi Arabia developed a facile and fast method to 3D print shape-memory polymer-based smart structures with a digital light printing 3D printer and custom resin. They combined a liquid crystal (a material that can change its shape with temperature) with resin, to introduce shape-memory properties to directly 3D print thermoresponsive structures—while avoiding the complexity of resin preparation. The team printed the structures with different geometries and measured the shape-memory response. The shape-memory polymers can be conveniently prepared for use as smart tools, toys, and meta-materials.

after I use the 3d printer I always get thoughtful about the safety of it (would be ideal if this happened the other day round) BC there seems to be not much known about the long term effects of resin exposure particularly in its uncured form. but it does seem like there are general agreements that

it's more likely to harm you over long term repeated exposures than a few mishaps

inhaling it is bad for the lungs and can cause asthma or breathing problems, again, probably over time rather than immediately

it almost certainly is a sensitizer, which means that if you repeatedly touch it with your bare skin you may over time develop an allergy to resin and resin products (booo)

there are probably carcinogens involved but that's true of nearly everything (not meaning this to sound dismissive in any way - but it could be the difference between like, cured meats vs benzene. but no one seems to think it's benzene levels)

I use my printer like this:

directly next to an open door to the outside (not a window, a full door)

nitrile gloves whenever handling raw resin

a mask when handling raw resin (the n95 type ones although I think I will just buy a half face respirator for peace of mind)

clean everything with alcohol (not water)

I clean the resin tank after every print as opposed to letting the resin sit there leaking fumes through the non - air tight lid

I leave contaminated objects in the sun for a bit to cure if cleanup is too annoying for the wet stuff

two charcoal air purifiers, one plugged directly into the printer and one just sitting on it

I'm not happy with the set up even with the door open BC I know I'm still probably inhaling stuff that won't do me any good long term, even with all the mitigations. am considering how best to do it 🤔 if I thought it wasn't worth doing risk-wise I wouldn't bother but I think with appropriate PPE and only using it infrequently it's probably not gonna be a massive issue - the most established health concern is actually the contact dermatitis and that kind of thing - this week is the first time I've used it in two years but I'd like to use it maybe 2-3 times a month or so going forward

here's a few links I found interesting (not co-signing these links as I fully don't have the knowledge to do so, i just thought they were worth reading as a new printer)
