Most 3D printer marketing makes everything look simple: unbox, plug in, print amazing things. The reality is powerful and rewarding, but also messier than the ads suggest. Here are some of the things I wish someone had told me before I bought my first printer.

1. Cheap Filament Causes Most Problems

A lot of failed prints, jams, and ugly results can be traced back to low-quality filament. Saving a few dollars up front can cost you a lot of time and frustration later.

2. Bed Leveling Matters More Than Fancy Features

If the bed isn’t level, nothing else matters. Auto bed leveling is worth paying for — it saves time and helps make everything more consistent.

3. The First Layer Is Everything

A bad first layer usually means a failed print. Learning how to dial in that first layer is one of the most valuable skills you can develop.

4. Stock Nozzles Wear Out

The nozzle on a new printer doesn’t last forever, especially if you print a lot or experiment with different materials. Plan on replacements or upgrades — especially to hardened nozzles if you use abrasive filaments.

5. Failed Prints Are Normal

Even experienced users get failed prints. It’s part of the learning curve, not a sign that you’re doing everything wrong.

6. 3D Printing Can Actually Earn Money

Once you get comfortable, 3D printing can become part of a side hustle — making custom parts, organizers, props, and more. It’s not instant money, but it can be a real, practical income stream.

Final Thoughts

If you go in expecting a bit of trial and error — and treat early prints as learning instead of perfection — 3D printing becomes a lot more enjoyable. The right machine, decent filament, and a realistic mindset can take you a long way.
