Being a recent owner of a 3D printer, I’ll likely be talking a lot about that. My printer is a Prusa i3 with 6mm aluminium frame and E3D 3mm hot end purchased from Semi-U in the UK. I decided to go down the self-build route partly due to the price but also for the possibilities that it allows compared to commercial pre-made products. With the RepRap style printers it’s easy to create your own upgrades to solve a specific problem, easy to add new features such as dual extruders at a fraction of the cost of commercial products. For me as a beginner to 3D printing it was an ambitious project but one I was confident I would get the hang of. The build went well and it was completed in around 4 hours. I’d go as far as to say this isn’t for everyone, there’s no instruction manual so you need to be able to look online when needed to work out what to do next. I did make a couple of mistakes which required ordering some replacement parts but overall it was a great experience and exciting to see the thing come to life at the end of it.
