There are three lists for things you need for this course. You may already have some of these. We’ve also tried to list links to Amazon for buying items. Some of the smaller items are not ones we’ve personally bought but the reviews looked good. The printer is one we’ve bought, assembled, and are currently using.
All prices are as shown on Amazon as of July 27, 2020 and do not include tax and shipping. Items eligible for Prime shipping are so indicated. If you don’t have Amazon Prime shipping will also cost something additional.
Basics – most essential
These are the things you really need to get any value out of this course. There is a readymade shopping list (3dprint-basics) containing everything in this section: https://www.amazon.com/hz/wishlist/ls/3752U50PKO1X9

Engineering essentials
These are things you need to do your own 3D printed engineering – mostly for measurement. This list with two items is also on Amazon here (3dprint-engineering): https://www.amazon.com/hz/wishlist/ls/1ZSJBXXA6LDB
Digital caliper Price: $22.95 (Prime eligible)

Network capability
These items allow you to put together an Octoprint server, which allows you to control and monitor printing progress over the network. You still need to visit the printer to remove things from the print bed, change filament, etc. but this really makes your life much easier. You can keep the printer in the garage and print from your laptop on the sofa. Highly recommended. Amazon shopping list (3dprint-network) at https://www.amazon.com/hz/wishlist/ls/2UQOOIG2UIUTW

Filament
This is the only real consumable supply you’ll use. The Ender 3 Pro comes with about 100g of filament, which is enough to print a decent number of things, but you’ll want to get at least one spool to start with. Note that buying filament can be a little tricky, because suppliers come and go, and sometimes a supplier we’ve had good experience with has their quality decline (or they may have a batch with variable quality). These are all ones we’ve purchased in 2020 and have had good experience with, but your mileage may vary!
Note that all filament shown here is 1.75mm. You cannot use other sizes.
Good PLA filament suppliers will ship it in a resealable large size ziplock bag with dessicant inside. When you’re not printing for extended periods of time, or when using a different roll of filament, keep your filament in the sealed bag with the dessicant pack. This will help it stay flexible longer.
