Cheap/Free Alternative: Plastic measuring cups will work as long as they have metric markings on them. Just be aware that they may be damaged by the resin. For a couple bucks more, you can get a durable glass one.
If you prefer to just print stock resin out of the bottle, you probably do not need a measuring glass. But to take advantage of the benefits of mixing up our proprietary blend of resins, you will need a measuring glass.
Cheap/Free Alternative: Some printers include a plastic measuring cup in the accessory kit. These work fine, but may not stand up to the resin for long.
If you prefer to just print stock resin out of the bottle, you probably do not need a measuring shot glass. But to take advantage of the benefits of mixing up our proprietary blend of resins, you will need a measuring glass.
Cheap/Free Alternative: Most printers come with a small plastic funnel in the accessory kit. These work ok, but they are typically small and made of plastics which may not stand up long-term to the resin.
Cheap/Free Alternative: Paper paint filters (the kind with a fine mesh in the bottom) also work for straining resin and are available cheap or sometimes even free at paint stores and big box stores. The work well for straining resin, but aren't reusable like the wire mesh strainers and also don't have handles.
Cheap/Free Option: Just clean and reuse the bottles you're already going to be buying anyways. Important note: the bottles Elegoo uses for their resin are polypropylene and therefore stand up to the resin, but the caps are not. I usually reuse the bottle once or twice and then discard it, because I have had a couple old caps break when shaking the resin - WHAT A MESS!
