Yesterday a reader sent me a comment with a question:
Please tell me more about your 3D printer.
I have a 13 year old son who is interested in getting a printer… [clipped for brevity]… suffer analysis paralysis over electronic do dads… [more clipped]
Please set me on a path to learn what to throw money at so the boy can make stuff with melty plastic, metal infused melty plastic, and electronic do dads.
Nerd bloggers like me live for questions like this! I can’t help but make a whole post. I hope it helps.
First of all dispense with analysis paralysis by just getting a printer. Buy it today. No printer is perfect so quit seeking perfection. The good news is basic printers are pretty damn cool. A 13 year old probably isn’t even going to imagine exotic print scenarios they can’t handle.
So just chill out and get a basic user friendly 3d printer. Which printer do I recommend?
I suggest
Bambulab A1 Mini Combo ora Bambulab A1 Combo.
There are better printers, there are worse printers. The Bambulab A1 Combo is (in my humble opinion) the sweet spot of “damn good but still not as expensive as more extra gooderer”. Mine has kept me busy for almost 2 years. Your kid won’t outgrow it right away (or ever).
The only difference between the A1 Mini and the A1 is build envelope. That one sided cantilever design looks hinky to me but (aside from build envelope) I’ve never heard complaints about the mini.
If you care most about being cheap and saving desk space the Mini is fine. The regular A1 is better. (Update… I just found out the difference is like $20… don’t even bother with the mini.) You can never ever upgrade the build envelope! (There’s a jumbo sized A2L. Don’t bother, you’re not going to need it.)
Here’s a photo of the Bambulab A1. All images are copied from the Bambulab website:

The photos show the base printer, not the COMBO. I absolutely recommend the “combo”. The combo includes an AMS Lite. Do NOT get a printer without the AMS Lite. (AMS means automatic material system.)
Here’s a photo of the AMS Lite. This is what it looks like with no filament. It will almost always have 4 spools loaded when it’s sitting on your desk. It’ll probably be cheaper to buy it with the printer instead of as an accessory later. If you don’t get it, you’ll wish you had.

The AMS Lite allows the printer to switch between up to 4 filaments in one print. In practice this usually means switching colors. (I mess around with alternate support materials and other nerd things too.) It also means your printer will “poop”. I’m not making that up.
Multiple colors is way cool. It’s a big improvement in printing fun. Don’t buy any printer that doesn’t have multiple filament capacity. Multiple filament stuff like embedding text into an object or adding racing stripes; that’s the shit that a n00b will most notice and appreciate.
I have to admit, Bambulab’s AMS Lite is the dumbest looking AMS I’ve ever seen. But they work, and very reliably so. They also take up a bunch of desk space but it’s worth it! If you want to make a white snowman with black boots and a red hat… AMS is the bomb!
Here’s the links on Amazon: Bambulab A1 Mini Combo (clocking in at $350) and Bambulab A1 Combo (clocking in at $379 on Amazon). Wait… it’s only $20 difference? Forget about the Mini, it’s dumb that it’s only $20 difference. Unless you’re Harry Potter and live in a closet under the stairway get the full sized A1.
You’re almost done with analysis paralysis but there’s a few more hurdles.
First of all, I offered links to Amazon. Check with https://us.store.bambulab.com/ too. You might get a better deal or you might not. Compare both sources and see if you get free shipping or whatever. MAKE SURE YOU’RE LOOKING AT THE COMBO.
One last decision, filament. A printer without filament can’t do a damn thing!
There are a thousand filaments to choose from… all are awesome. You can never have too much filament. Sweet sweet filament…
Where was I? Oh yeah, you have no idea what you want to do so you have no idea what filament to buy. I suggest PLA. It’s the easiest and doesn’t require a dryer. (If you like the printer and want to “expand” to PETG and other neat filaments your next purchase will be a filament dryer. Don’t worry, it won’t be overly expensive.)
I recommend you buy Bambulab brand filament because the spool has an RFID chip that will “tell” the printer what the filament settings ought to be. (Other brands are fine in the future, I don’t recommend it for a beginner.)
Buy at least $100 worth of PLA filament in whatever colors your kid likes. Make sure at least one color is something your wife likes. Filament comes as “refill” or “on the spool”. Buy “on the spool” at first. Save those spools and reuse them with “refills” later.
Filament is addictive. As soon as you buy red to make a racecar, you’re going to wish you’d bought green to make an army jeep. Bambulab uses the “get them addicted” pricing plan. If you buy 4 items you get a 25% discount, buy 6 and you get 30%. Accept your fate and buy no less than 4 spools to get that sweet 25% discount.
You’ll be happy with PLA Basic. That’s not as limiting as it sounds. Maybe buy one in PLA Translucent because translucent is cool. There’s a new thing called PLA Pure which I haven’t tried. It’s (with caveats that are more legal than real) food safe-ish. I wouldn’t bother unless your kid is going to chew on his creations.
Some filaments like PLA Wood and PLA Glow will require swapping nozzles. Don’t go there at first. Stick with the nozzle you’ve got.
4-6 spools is plenty to get started but don’t hesitate to buy more filament in the future. If you print a lot you’ll crave it like Scooby Snacks. Also, when I started I thought PLA was “weak” and I immediately branched into slightly more difficult to use PETG. I’ve since tested PLA and it’s surprisingly tough. Don’t assume PLA is wimpy “beginner junk”.
Exhausted yet? Almost done. Either you or your kid should make an account on https://makerworld.com/. If possible do this before or in conjunction with buying the printer itself and your first hit of crack… I mean filament… Maybe you’ll get extra discounts, maybe not.
Your Bambulab product will want to “phone home” (to the horror of libertarians everywhere). Relax, go with it at first and unplug later if you want. Your kid is not an international expert in engineering who’s building ICBMs in the living room. You can fret about privacy later. Your account in https://us.store.bambulab.com/ and https://makerworld.com/ will get along together. There is also a cell phone software called Handy that your son will have setup faster than you, as a dad, will be able to do.
I recommend having a computer nearby. Any computer will do at first. (Later when your kid is making his own stuff you might want a “good” computer.) Running from cell phone is lame and limiting; even if your kid loves his phone running from a real computer is a better experience. Everything goes through Wi-Fi. There’s no cable connection needed. It’s wise to put the computer where you can babysit the printer while you’re sending it data from the computer. It does have a camera, you can turn it off and/or cover it if you wish.
When the printer arrives give yourself an hour or two to get it set up. It’s easy but don’t rush. The software (on your computer) called Bambu Studio will take 15 minutes or so, assuming you remember the login & password.
After that your son can surf to https://makerworld.com/ to select from a zillion “models”. It’s a nice glide path into the hobby. You can select models that match your printer (A1) and your filament (PLA) and most (not all) are pretty sweet. Start with something small and simple. Don’t freak if something goes wrong, though the simple stuff might work right away.
You are required by law, custom, and etiquette to print a Benchy. Don’t worry if it sucks, you’ll figure it out as you go. You’ll get better with time. Print it, examine it like you know what you’re looking at (even though you don’t), and if you ever get bored… print another.

That’ll overcome analysis paralysis. If your kid turns into Tony Stark you can always upgrade. But that’s probably not going to happen and he will likely be happy with something that’s easy enough to use and good enough to reliably work. (I haven’t gotten bored of mine and I work it like a rented mule.)
I hope that helps.

P.S. If your kid is specifically and hard core interested in minifigs (and nothing else), you may have to deal with a different technology called “resin printing”. That’s a whole different animal involving vats of messy fluids. Don’t go there unless he’s limiting his world to minifigs. Ask him if he wants a Warhammer 40K tattoo and seems obsessed with teeny tiny paintbrushes… if so, you may have to consider resin.
P.S. After you’ve had the printer for 1-6 months, take a look at CyberBrick. I built the remote control forklift. I had absurd levels of fun making it. You, as an adult, might be more interested in CyberBrick than your son. Or not. You two can make remote control devices and have friendly in-home robot wars… good clean nerd fun. But wait until your son has had a while to 3d print simple things like keychains and fidget spinners.











I assumed the 2″ ball was seized up and sprayed liquid wrench on everything. I probably didn’t need it. With a few taps of the hammer, the locking shaft mechanism worked pretty well. Wow! I wire brushed all the crud off just because I ought to.
