The technology to look for in LCD resin printers is a high resolution monochrome LCD. They allow much more UV light through than the color LCDs and last longer before degradation from the UV light exposure ruins them. But since these printers are pretty much the only reason to revive old mono LCD technology, they come with a premium price - but the per layer speed is considerably higher.

I think of the current state of resin 3D printing as similar to the early days of photography - nearly magical, but there is some inconvenient slopping of chemicals to make the magic work. We need the 3D printing equivalent of digital photography with all of the magic, instant gratification, and without the messy chemicals. However, a little rinsing with isopropyl alcohol, air drying, and UV exposure to cure the surface is a minor price to pay for the resin 3D printing magic. It's SO much easier to CAD a structural part and resin print it than it is to use CNC to make the part. I complain about the IPA rinse, but it's much faster and easier than cutting raw stock, fixturing, breaking end mills, tool changes, clearing chips, multiple fixture setups, tumble deburring, etc. As an added bonus, I can 3D print parts that can't be made by CNC or injection molding. Small parts can be arrayed and they 3D print as quickly as a single part when using MSLA where the entire layer is exposed. Resin printing is an incredibly powerful tool in my engineering toolbox. > Do you have an MSLA right now? What model? I have a Qidi Shadow 5.5S and a Qidi S Box. Both are budget resin printers that do a good job, but there are probably better options now. We're still fairly early in the MSLA technological development. Prices are falling as the quality and features improve. I've had good results with Saraya Tech ABS-Like resin. It prints well at the printer's default settings. I hung some parts outside in direct sunlight all summer and there was no degradation in strength or loss of aesthetics. The quality of the available resins is quickly improving too. I'm hoping the supply catches up to the increasing demand and the prices fall to a penny a gram. Resin printing is enabling a lot of small businesses to make great niche products that wouldn't be viable if they required expensive high volume injection molding. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
