I'm going to buy a 3D printer

https://www.youtube.com/watch?v=tFB0sSKUN1w Maybe watching his vids may shed some light but it is truly hard to answer that question unless you have a specific idea in mind of what material you want to print and what kind of models you want to print.

Hi Marvimation.
Yes, I'd like to print some of my models, starting with simple objects like the bucket I made and getting to some more complex shapes like other models I have and I'm going to create.
Practically something not so expensive (not $800 - $900) but less ($310 - $380). if it's $400 is fine as well but something to start with decent results and not bad defined shapes.

Hope I give you the idea :)

You should go with cheaper plastic I think to start out with... I heard 3D printers are quite expensive to run, cost of plastic materials, electricity and also they are affected by weather conditions. Too hot might mess with the cooling process and too cold may make the printing slower or jam the machine if the plastic doesn't melt. So keep all of those things in mind.
All 3D printers that are under 500 require quite a bit of tweaking and manual construction on your part. I heard someone say that if you are used to assembling Tamiya 1 10 scale model kits you should be fine but also think about the fact you need to assemble certain parts.

Thank you so much Marvin, I'll keep your advice in mind :)

When you buy the printer and work out all the bits and bobs and costs I think I may commission you to print some of my models if you are up for that kind of thing. I noticed that printing companies are super slow about getting back to people about quotes for stuff. Not sure why that is but it is quite annoying.
