Re: Maximum speed - 6 years ago
Afaik you need latent heat of melting (∆Hm) for PLA. This won't be a fixed value as I believe it depends on the degree of crystallisation for the specific type of PLA. Either way it's already well known different PLA melt at different temperatures. Agree those figures seem well off, 30W or 40W heater is commonplace and 50mm/s wouldn't be categorised as especially fast at most usable layer heightsby plasticWrap - General

@JamesK Thanks, mostly I find the time / hassle to swap nozzles is the problem. Printing the scaled down items doesn't take long as it's still a lot faster than printing a full size item with the 0.4, but I don't fancy changing the nozzle often so I just thought I'd get all the small ones I wanted to see done now. Hence why I tried to do a run of them, other hotends may have a more straightforwarby plasticWrap - General

@MechaBits Thanks, can never have too much filament @the_digital_dentist I remember your instructable, think I read it back when I was looking for my first kit / printer was an interesting read and print quality looked very good. In terms of reliability / repeatability, on the basis of my testing I would say provided all the settings and preparations are the same then the results should be tby plasticWrap - General
New adventures in 3d printing (aka so I designed a 3d printer) - 7 years ago
Hi all, I've been a member for a while but this is my first post. So after a little while with some kits I decided to design and build my own 3d printer. It was mostly just supposed to be a stop gap design so I could build decent parts for other printers and another design of my own later on. I couldn't find exactly what I wanted amongst existing designs but I knew there was some key elements Iby plasticWrap - General
