Beginners' guide to 3D printing
Beginners' guide to 3D printing
I've just posted a beginners' guide to 3d printing on my blog.
https://riksrailway.blogspot.com/2021/1 ... nting.html
I've tried to keep it straightforward and uncomplicated so as not to deter someone who's thinking about taking the plunge while also trying to give them a feel for what's involved.
I'd be interested in any feedback as to what you think is ok, where there is information overload or what essential information is missing.

PS Or if you spot any errors or typos as has already happened

Re: Beginners' guide to 3D printing
Generally excellent Rik, as always with your writings.
I did spot one typo - in the section where you describe the use of Pritt tyou say that it needs to be "relied" which I think should be "reapplied".
Some of the details/procedures that you describe are rather different on my FDM m/c, but I guess that would apply whoever the manufacturer is.
As for Tinkercad, you and Steve have undeniably demonstrated how good the drawings can be. I had yet another try a couple of weeks ago, with no real joy at even the simplest level, however since I was going away for a week in Scotland ( last week) I was deteremined to get it into my thick head whilst on holiday. Unfortunately, the 'net connection wasn't good enough to be able to do anything at all, other than read the board and read mails with a bit of a struggle. That of course is a big problem with doing anything that is 'cloud' based, whereas my good old obsolete Sketchup was perfectly happy, residing on my laptop.

Re: Beginners' guide to 3D printing
That’s really helpful. Thank you.
My first problem (I realise, of course, there will be a zillion more) will be where on earth to put the damn thing. This may seem ridiculous but — does it (printing) smell? This could limit my options…

Re: Beginners' guide to 3D printing
Yes there is a smell but it isn't particularly strong or obnoxious. We live in a bungalow and I have mine in a spare bedroom that I use as a kind of workshop. The door is always wide open and SWMBO is always on my neck about anything even vaguely smelly but she has no problem with it. I think ABS smells more strongly than PLA though.

Re: Beginners' guide to 3D printing
Thanks. That issue has been raised on another forum (GSC) in relation to ABS. Pleased to report that there is very little odour with PLA which is a plant-based plastic (made from corn-starch I believe). PETG has a very slight odour but not unpleasant.

PS Just noticed Philip has beaten me to it
Re: Beginners' guide to 3D printing
Thanks - I did spot that after I'd uploaded it, but didn't make a note of the error and where it was so when I went back to edit I couldn't track it down. I'll correct it now...

Re: Beginners' guide to 3D printing
Only comment I've got on that otherwise excellent guide, you don't need adhesive 99% of the time. I don't use it at all on my 3 soon to be 4 printers. Level the bed, fine tune your bed temperatures and you'll be fine. I find the hotter the bed, the more likely your part is to stay attached.

I'll try without Pritt but the last time I tried it I had all sorts of adhesion problems using PLA

Re: Beginners' guide to 3D printing
As I think I've said before, I stopped using Prit a couple of years ago and I haven't had any real problems since. I think I agree with Jon that getting the bed temp right is the answer. I set it at 60deg for initial layer then drop it to 50 for the rest of the print. Of course the plastic sheet on top of the heated ali build plate probably drops the actual temp by a degree or two.

Re: Beginners' guide to 3D printing
On my brand new Creality Ender 3V2 I have found that if I do not use the glue (Pritt, UHU or equivalent) I have no end of adhesion problems.
It has a glass bed with some sort of coating on it and the bed temp is set at 60C by default for PLA. I also have to use a brim otherwise the adhesion is just woeful.
I have levelled the bed so many times I can do it in my sleep.
I will look at increasing the temp to heat the glass to a higher plate temp, I generally leave the printer in "preheat PLA" mode for at least 5 minutes before attempting a print.

Re: Beginners' guide to 3D printing
I've had intermittent issues with prints not sticking. But I've upped the print bed to 65C and it stays there all print. Now I have hell getting the things off at times rather than keeping them on!
