I know SolidWorks well enough to be dangerous as I needed it for work from time to time. Still using it now. But when bought my A1-mini, I printed everything from MakerWorld for the first month or two, love the fidget stuff, decorations for my wife, puzzles, cool shite, gifts, etc, etc. I was and still am fascinated watching the printer build the part. Then I started my designs on needs and haven't looked back. I think I printed every day for 9 months straight. To all that are nervous, aren't sure, etc, don't sweat it. If you truly aren't sure if you need it, you can try the A1-mini as it is cheap and a workhorse. Upgrade from there. I still don't have an AMS but one day I might add it. Learn how it works, play with it, print fun stuff, give your prints away, enjoy it and then start with small projects and build your skills as the need arises. Don't worry about the filaments as most things can be made in PLA or PETG and both can be used on the A1-mini. Maybe this is redundent information at this point but when I hear about concerns, just get comfortable with the 3D printing technology first before you try your hand at design software. IMHO
