Always consult the safety data sheet (SDS) as the primary source of information to understand safety and handling of Formlabs materials. Oligomers, star polymers, and hyperbranched systems are generally end-group or pendant functionalized with these photoactive sites for use as SLA resins. Resin. Not Weak At All. All SLA resins are made of photopolymeres engineered to turn solid when they are exposed to light. We have staff members here who cannot use our SLA machines at all anymore due to too much exposure - they get everything from itching, rashes, hives if exposed to the resin. In general, nitrile gloves and isopropyl alcohol will have you covered. Learn more about resin and how to keep yourself and the planet safe. Don't mess around with Stereolith resin - as other comments mention it affects the immune system and can cause various allegic responses. Warning: Poison hazard: Never ingest resin in liquid or solid form. It is a better cleaner and much cheaper! In any case, you would want to avoid letting any of these fumes enter your respiratory system. 3D printing resin can affect users and the environment. Resin basics. The raw material used for SLA is liquid resin, typically contained in a large vat integrated into the printer. Formlabs SLA printers print parts using photoreactive liquid polymer resin. Make sure you have the proper Personal Protective Equipment (PPE) whenever you are working with your SLA 3D printer. The curing process is the same; therefore, the waste after curing is still hazardous waste and needs to … These are generally toxic, and miscibility issues are a concern with photopolymer resins, leading to photoprocessing complications. SLA resin prints aren't famous for their strength. Stereolithography (SLA or SL; also known as stereolithography apparatus, optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and oligomers to cross-link together to form polymers. Our 3D resins are made to order and most of them are ready to print with any open and closed mode SLA, DLP, LCD & Inkjet printer, including the Form 2 & 3. I am an SLA printing noob. One big health and safety concern related to the use of 3D printers is the fumes that get emitted when plastic (or any other material) from the filament reel gets melted by the printer. ... As with any type of 3D printing, printing with resin releases a slew of fumes that can range from irritating to toxic. I have been looking for safety data sheets to tell me how to handle and dispose of used resin, but I don't seem to be able to locate any on the internet. Resins are tricky, but probably less tricky than FDM as the manufacturing process is much less likely to include contaminants in the shape of contaminated air, particles, or adding lead into the print. 3D printers can often run overnight or for long hours as it prints a model layer by layer. Mean Green is $5/gallon at Lowes, compared to $15/quart for Denatured Alcohol and $25/gallon for 99% Isopropyl Alcohol on Amazon. ... Low odor resins are less toxic to breathe, but you still need to take precautions. (07-18-2019, 10:14 AM) mediaman Wrote: I highly recommend using Mean Green (or Simple Green if you can't find Mean Green) to clean the resin off your prints. SLA Resin Strength: How Strong Is 3D Printed Resin? Unlike the plastics used in FFF 3D printing, the resins used in SLA 3D printing are not inert and are actually a skin-irritant in their uncured form. SLA 3D Printing: Is 3D Printer Resin Toxic? 3D printer fumes. Selection of pictures of our 3D printed resins. I understand that SLA resin is pretty toxic stuff and you can't just pour IPA solution saturated with it down the drain. Special 3Dresyns which may need fine tuning will include free samples of our Fine Tuners FT1 and/or LB1 Bio.
