Why would you 3D Print Lego?

If you can go ahead and buy a complete set of Legos all by yourself, why to even bother about creating these by yourselves?

Go Creative: What 3D printing is known for? Of course, freedom. The technology has brought itself the long trail of creativity that is difficult to surpass by any other technology. You can design your own creations using 3D printing. You can create pieces that never existed before. Something that could actually make you famous in a day. Even not, it would be fun to turn your imagination into real objects.

Print Missing Lego Parts: Are you in between your build and realize that you may fall short of a few Lego bricks at the end. Don’t let the dilemma get the best of you. Think harder. If you have a 3D printer sitting next to you, why not use it. Easily find the online STL files and download the file to print yourself a replacement brick.

Bring Your Childhood Days Alive: There are times when we try to search for those old school Lego sets that happened to exist when we were a little child. Sometimes, it’s harder to get rid of the annoying feeling of separation. But with 3D printing, it is simple to build. And, if you already have a few pieces left from your vintage collection, you can complete the entire set with 3D printers. Unbelievable, isn’t it? You can check the dimensions and if you are good at printing models, it won’t be that difficult for you.

3D Print Adapters: Lego does make a world in itself. However, introducing new meaning to the fun is much more exciting than we can realize. The example is cited right above. A Duplo adapter that can make tracks more fun when upgraded with Lego hacks. The same can be done with other games. You can make things compatible using Lego blocks. And, it’s very amazing to watch its succeeding.

Ready Whenever you Are: Online deliveries take time. And, patience often leads to frustration when seeking something faster. Using 3D printing, you can create your missed parts in hours. Or, even the entire set would not take much longer. So, why not just feed the file to the printer and wait for it to get you the parts in a matter of time rather than waiting for a delivery boy for days or even weeks.

It’s Actually Cheaper: Definitely, it’s after subtracting the printer cost. This is because the operational cost along with the material isn’t very high. Especially when you are working with an FDM 3D printer. PLA is the cheapest material, can certainly work for Lego designs. Because each Lego brick would cost not more than a few cents, printing replacement parts are much cheaper than ordering the complete set for just a few missing pieces.

Which 3D Printer to Use for Creating Legos?

Whosoever you ask, you need nothing more than an FDM printer to get the job done. The machine with a standard 0.4 mm nozzle would nail the task.

If you have an expensive 3D printer, certainly achieving the required tolerance would be much easier, that does not mean the budget ones won’t be able to get you the results. With FDM printers, you get to choose between a variety of colors and materials.

However, on the contrary, for very small pieces, you may feel the printer falling short of results. In that case, you may like to use the SLA 3D printer for precision. But remember, you will have to trade-off cost, variety of color, and material options when wanting high resolution and unmatched precision.

What we recommend is to use the FDM printers for the job. These are sufficient enough to process the prints with desirable accuracy. And, these are cheaper options as well.

What Material to Use?

There are a few materials that could hold your project high.

ABS

Let’s start with ABS. This is the closest match to the material used for real Lego bricks. The real Lego parts are created using injection-molded ABS.

Hence, FDM ABS is the best material for printing these pieces. When using ABS, you can achieve the similar toughness and resilience found in the store collected Lego parts.

PLA

This is the cheapest one you can choose. And, it is also bio-degradable. Being the most popular filament in 3D printing, it is impossible to ignore the fact that these can also print Lego parts.

However, these won’t be as tough as ABS printed pieces. The Lego parts will have low tensile strength. And, if you accidentally step on these pieces, they would snap.

PETG

petg-filament-for-3d-printing

This is an intermediate option. It’s easier to print with PETG than ABS and higher in strength than PLA. However, these won’t look anything similar to the ABS printed parts.

And, you would come to know about the difference right after you try to connect the ABS printed parts with PETG ones.

Limitations of 3D Printed Legos

While 3D printing is a huge success, there are certain limitations that still hold the technology to seep into the mainstream of Lego creation.

Needs Time for Accurate Results: If you have worked with 3D printers, you must know that the settings are not standard and may vary depending on the make of your 3D printer. Hence, you do need to experiment a lot with your machine when printing Lego parts as these must fit into each other. With trial and error, you could discover the best settings for your slicer when printing Lego bricks. This needs patience and effort.

Lacking the Exact Glass Like Finish: We do not want to disappoint you; the printed Lego parts aren’t as attractive as the ones available in the market. The glass-like surface finish won’t be available with these 3D printed Lego pieces. It hardly matters though, if you believe more in experience and fun.

Apart from these limitations, one must not get the strength available with store Legos when printing with PLA. Also, if you plan to use ABS, printing would be tricky.

As ABS is prone to changing shape exposed to fluctuating temperature, you must use an enclosed 3D printer to work for these designs.

A consistent temperature is a must pre-requisite when working with ABS. Or else, even slightest of change in the shape would make the parts unfit for each other.
