Having just read an interesting "What I did with my 3D printer" thread, I
wondered which 3D printers DIYers used, and why.
A quick look online seems to show printers in the £200-£400 range so there
would have to be a significant saving to cost in for making one off parts.
I can understand the "Uh, duh, because 3d printing!". Just wondering if
anyone has cost justified a purchase on the savings over buying stuff or
throwing away something as unrepairable.

It is interesting in that unlike turning which is a subtractive process
3D printing is an additive process so you can make curious intricate
objects limited only by your imagination.
If you want to dip your toe in the water using high end kit on a time
and materials basis find your local hack space (likewise laser cutting).

They are fun but whether a home users can make a profit out of them I'm not
yet convinced. If it's just a hobby fine, who cares if it takes 3 hours to
design the box and 2 hours to print it with £10 worth of materials.
A mate, liking the idea of one, conscripted his Mrs to do the research
and along the way asked me two things:
1) Could I give them any advice re what to get and:
2) Whatever they got, could I help them build it (they wouldn't get
one if I said no).
As I hadn't even used one and only seen them on the telly or at
Engineering shows *, I did a bit of Googling and found several things
I understood to be important and fitted 'our' prerequisites.
a) It needed to be a kit (none of us had the time or experience to
source all the bits individually).
b) It needed to be rigid.
c) It needed to be RepRap / open source as much as possible.
d) It needed to come from the Uk (for support / spares etc).
e) It needed to have a good rep.
She ended up with a MendelMax 1.5 (kit) and we (he and I) built it up
in our spare time and I'd have to say we were very pleased with it.
The very first real test print, a 20mm cube turned out to be just
I was then worked hard every day (often 10 - 6) printing all sorts of
stuff for all 3 of us and also bits for others, as the mood / need
took us. It's very much like this:
It's also printed all the plastic parts for two more printers now. ;-)
That didn't even come into it for us.
I haven't ... as that wasn't (as you say), 'the point'.
More the point though, some of the practical uses we have put it to
have allowed us to do stuff that would have been very expensive or
very difficult to have done without and so we consider it to have paid
for itself (in time and convenience, if not in cost etc).

The biggest item / longest print time was the PIR lantern corner
bracket because printed on it's side it was nearly size of the bed (in
an 'L' shape) and quite a bit of the maximum print height.
Also, because it needed to be reasonably strong we printed it at a
fairly high density.
We would also often print multiple items at once (like more printer
parts) and the limit would be how long the job would take (to ensure
it fitted into a working day). Nothing worse than having to abandon a
8 hour print job on 99% because mate had to shut shop and we didn't
want to risk leaving it on unattended. ;-(
To be fair we also had the speed settings set to 'conservative' as
that proved both more reliable and gave a better finish.
So, it wasn't really what we were finding to print but what we needed
I would often design something in the evening that I needed (or would
like) to use the next day (like a drilling template or part for
something), I would Dropbox it to my mate and pick it up printed at
lunchtime, assuming he wasn't printing something for himself or his
Mrs (like a tool, bracket or storage for her vape stuff or the 3D
object scanner he printed for himself).

My view too. But if you know what you are doing (as Andrew Mawson's
fluorescent tube thread shows) they are beginning to get useful for some
DIY. (I know someone who's lad has one, but AFAIK he's only done "art"
Should be ideal if you have little kids that are obsessed with stuff like
dinosaurs and cars etc, easy to make them more of them cheaply.
Havent worked out if they pay for themselves in that situation tho.
The ~£99 ones ebay have the same resolution as the £1000 ones in general.
You only get a significantly better resolution when you go for a resin
printer using a laser and UV resins.
I would expect a 0.4mm nozzle and 0.2mm layer height even from a £99
printer and you can probably replace the nozzle with a 0.25mm one.
The £99 will probably require more tuning to get the best results.
I was thinking more of something like the Ultimaker 2+, which is nearer
I've not seen any that offer better than 350-400 microns layer height.
The Ultimaker 2+ can get down to 20 microns and includes a 0.8mm nozzle.
It will also work with much more useful materials than PLA, such as ABS,
nylon and polypropylene.
I would hope you mean something smaller than that.
0.8mm is like the volcano nozzles you can buy for ~£30 that are used to
print thick layers more quickly rather than print fine detail at higher
Both my sub £200 printers go down to 100 micron layers, there isn't much
point in going lower with FFF printers as it would take days to print
anything. Its where resin printers take over and they start at about
£500 these days (unless you want a kit).
You need a £20 upgrade to make the £99 printer work with those
materials. One of mine will print those and a few others like carbon
fibre filled stuff, the other will only do stuff that doesn't need a
heated bed so PLA, PTG, etc.
All you need is a heated bed and an all metal hotend which cost very
little from china.
I have just bought the equivalent of a microswiss hotend for £4 to fit
my mk9 extruder but I need to drill the heater block out to 6MM and tap
it 7mm which I haven't got around to yet.

3D printers are fun if you have the time and patience.
I'd want one with at least 2 heads if not 3 and the ability to print more t

?600 & £1,500
but as yet I don't really have a good use for one.

I've had enough studetns here doing it 24/7 and we have two 3D printers in
the lab. if I'd brought them I wouldn't be too happy paying a grand for the
m athough they have two nozzles and can take two types of plastic.
The printer we have downstairs is about 40K and another in SEMS is about 1/
4 million now that is impressive.
