DIY Legos via 3D Printing: Cost-Saving or Just Cool?

Hey tech enthusiasts! Carolina here, your ultimate techie guide, bringing you the spicy details on something every tech lover has pondered upon – 3D Printing Lego! ️ Dive into this electrifying ride to understand the in-depth process. Get ready to feel the vibes and connect with the world of 3D printing like never before.


Can You Craft Legos using a 3D Printer?
Oh, absolutely! Ever wondered if you can churn out Lego pieces using a 3D printer? Guess what? It’s not just a fantasy. With both filament and resin 3D printers at your disposal, the possibilities are endless. Sites like Thingiverse are bursting with numerous Lego templates waiting for you. And, for those wondering, yes, even a basic Ender 3 can be your Lego-making sidekick. Getting that impeccable fit might require a bit of tinkering, but, oh, the joy when you get it right!

Now, I’ve come across a plethora of tech enthusiasts who’ve turned their filament 3D printers into Lego-making machines. The outcome? Absolute perfection, especially with the Ender 3D printer. Pro tip: a tad bit of post-processing, say a bit of sanding, gives that perfect finish to your printed Lego bricks. And for some extra dose of awesomeness, there’s a fab video out there showcasing a magnificent 3D printed Lego-themed garden. A must-watch!

Steps to 3D Print Lego with Pizzazz:

1. Grab or Craft Your Lego Design: The simplest route? Download an awe-inspiring design from PrintableBricks or Thingiverse. For those with a flair for creativity, designing your own can be exhilarating. Just ensure your measurements are on point! Dive into software like Fusion 360 or TinkerCAD and let your creativity run wild. Did I mention you could even 3D scan your existing pieces? Try the Revopoint POP Mini Scanner – a game-changer!

2. Pick Your Filament with Finesse: Debating between PLA, ABS, or PETG? While PLA is a hot favorite, real Legos are crafted from ABS. PETG offers that luscious glossy finish, making your Lego shine. But if you’re aiming for an authentic Lego feel, ABS or ASA filament might be your best bet. My personal favorite? The PolyMaker ASA Filament. It’s the closest cousin to ABS and it’s sun-loving with its UV resistance. On a side note, the SUNLU PLA Filament has been creating quite a buzz with its vibrant colors.

3. Fine-tune Your 3D Printer: Want those Legos to fit like a dream? Calibration is key. Focus on extruder steps, XYZ steps, and that perfect printing temperature. A quick hint: A temperature tower can be your best buddy to get the heat just right.

4. Tweak Your Horizontal Expansion Setting: Dive into Cura’s Horizontal Expansion or PrusaSlicer’s Elephant Foot Compensation. Adjusting these settings can make your Legos snap together effortlessly. And if you’re looking for numbers, 0.4mm has given some fantastic results. But hey, feel free to play around and discover your magic number.

Economical to 3D Print Legos?
When it comes to bigger and intricate models, 3D printing might be lighter on the wallet. But remember, experience and precision are paramount to avoid misprints. Cost-wise, a 4 x 2 Lego piece weighs in at 3 grams, which sets you back by approximately $0.06. Some enthusiasts have snagged second-hand Legos at $0.04 a pop.

Considering the material cost, electricity, potential print failures, and design availability, 1KG of filament (costing between $20-$25) can yield 300 Lego pieces of 3 grams each. Legal issues might be a minor hiccup, but there’s an abundance of designs out there.

For instance, the LEGO Technic Heavy-Duty Tow Truck, with its 2,017 pieces, has a price tag of about $160 ($0.08 per piece). Replicating such intricate designs might be challenging. But for those dedicated tech lovers, with time and patience, anything is possible!

Well, that’s all for now, folks! Dive deep into the 3D printing universe, and let’s craft some Legos!
