A quick repair today for an old Michelin Man figure. Only the head needed replacing, so this simple model will fix it right up.

So, what actually is PLA?

PLA is probably the material you'll see most often in 3D printing, and it's one of the materials I use quite a lot at Cosmic Forge.

PLA stands for Polylactic Acid and is a type of bioplastic. It's generally made from renewable plant-based materials such as corn starch, sugarcane and other agricultural sources, which are processed into the plastic used to make the filament.

So what is PLA actually good for?

I find it works really well for things like:

• Decorative models and sculptures
• Figures and collectibles
• Prototypes
• Cosplay props
• Lithophanes
• Board game pieces
• Display pieces
• General household items
• Projects where heat resistance isn't a major concern

One of the biggest advantages of PLA is how easy it is to print. It produces good detail, has a huge range of colours and finishes available, and is generally a great choice when appearance is important.

The main downside is heat. PLA doesn't handle high temperatures particularly well, so something left inside a hot car can soften or deform over time.

That's why I don't just use PLA for everything. Depending on what a part needs to do, materials like PETG, ABS, ASA, TPU or PETG-CF can be a much better option.

The right material really depends on what you're making and how you're going to use it.

Just about finished with this Dr. Doom mask. Only need some magnets and the mesh pieces and it's done!

Still needs some post processing clean up though.

As a huge Halo fan, I had to print this low poly Ghost. I think it came out quite nicely! Might print it in a lower layer height next time though
