Before you buy your first 3D printer: five questions to ask

Printers that once cost thousands now cost a few hundred dollars, and many set themselves up. That's great news, and it also makes the choice harder. Answer these five questions first. They'll narrow the list faster than any review.

1. What do you want to make?

Toys, gifts, and desk organizers print well on almost any current printer. Parts that have to fit, hold weight, or survive heat need a printer that handles tougher materials and prints accurate sizes. Write down three things you'd print in your first month. That list is your real requirement.

2. Who will use it?

If kids will be around it, look for an enclosed printer or plan a spot they can't reach while it runs. The nozzle and bed get hot enough to burn. For beginners of any age, automatic bed leveling and a simple touchscreen save a lot of frustration.

3. How much tinkering do you enjoy?

Some people love tuning a machine. Others want to press print and walk away. Kits and budget printers can print beautifully, but they often ask more of you. If the goal is making things rather than fixing the printer, pay for the features that handle calibration for you.

4. Where will it live?

Printers need a stable, level surface, some airflow, and a spot where the noise won't bother anyone during a long print. A garage that swings between hot and cold can cause failed prints. A shelf in a spare room or office often works better.

5. What's the full cost?

Budget for more than the printer: a few rolls of filament, a spare nozzle, a scraper, and a way to store filament dry. Many people start with PLA, the most forgiving material, and add others later.

A simple next step

Take your answers to a store or a friend who prints, and ask them to show you a printer running. Seeing a first layer go down tells you more than any product page.
