Its over 2 years not 1, makes it quite expensive and it's based on quite old tech, so will be pretty much obsolete by the time it's finished.


2 of the chaps at work have the one on banggood.com and are praising it very highly, although the build area is smaller than mine
I'll post a link later as I'm on the iPad and copy n paste is not its strong point

Right.... feed jam fixed :) (so far lol)


Looks like the feed motor pinion for want of a better word had not been tightened properly or had worked loose.  A drop of blue theadlocker and a quick tighten.... job done


Another issue was the feed tube....the filament was not running freely through the tube causing stoppages.  Some research online yeilded that these tubes are indeed problematic, and should be replaced with PTFE tubing


Print job now running :)

A very useful object to print, nice and simple although it does take around 2 1/2 hours to print.

Print job at 14% and looking good so far :)

ok if it is only at 14% now are you going to trust it to do it's own thing overnight or can you stop and restart it....I wouldnt like a hot machine running without supervision

now at 36% ill shut it off at midnight lol.... tho you can pause the print


the current print job is started about 10:30pm.  Had a few more feed issues which I have solved by changing the Filament to a new roll.
Checking the roll that was supplied the dimameter was inconsistent which was what was causing the jams

Longest print I've done so far was 44 hours.


Over the past few days I've been printing parts for a 1:16 20ft container. Each part takes between 7 and 10 hours to print (I print quite slowly). At some point I was worried there'd be enough material on left the roll to complete the print. Was a bit of a close call : there was only ~2m left after the print was complete (keep in mind there's approx 60cm that runs to the print head and is always lost).

I can post up some pics of last nights attempts but there's nothing much to see.... Some cubes and circles of plastic


As for a how to, I found a very interesting book online. Pm me your email and I'll send a copy


When I have access to a decent keyboard (not my iPad) I'll post a more in depth review with pics

PM sent.

Saw this linked on another forum. Something a bit more interesting to print out, which might serve your interest a little better.

Will give that one a go.  Maybe not to use in anger but more as experience

getting there


I cant seem to get it printing in HQ mode without making a mess :(
However the more tinkering I've done the better the prints.  It just takes time to get the feed rates and nozzle temps right.


I think I will stick to one brand/supplier for filament as I have noticed that different filaments require different settings.  I have 2 spools from the same supplier (red and Black) and they work better at different temps (190 for black and 200 for red)


Have to say tho its quite time consuming and its not really something you can just plug in and go, no matter what the adverts say.


My initial conclusions are that its a great bit of kit with huge potential, but the finished quality isn't quite there at the budget end of the spectrum. (If you can call 400quid cheap lol)
I think mine will be used to prototype parts with the finalised parts being ordered from Shapeways


If anyone wants anything printed as a proof of concept/prototyping then I'm happy to do so.

A little update :)


Trying to use the water soluble PVA filament ended up ruining the nozzles as when the stuff overheats its burns and leaves a residue thats nigh on impossible to remove.


On the whole its working OK, but more even tinkering is required

Good luck with your 3D printing.
I had a miniUP! printer for 18 months or so, and initially, produced good results.
But how you form your cad model also has an effect on quality.
A major move on my part last Christmas, means I no longer have either of my printers.
The attached photo is of a horizontal steam engine at 1/10th scale. The file was for a full size engine.
This was a complete set of parts right down to the piston rings, and all printed successfully, but could not repeat this quality just before I gave the printer away.
Stick with one supplier for your filament, it varies so much, and remember - rubbish in rubbish out.
And it does absorb moisture, so keep it in an airtight container, with silica Gel.. until needed.
cheers :-))

The things I have been producing have been pretty simple.
I have been using Tinkercad
https://www.tinkercad.com/
you need to register but its quick and easy to pickup


Heres the servo mounts I designed an printed for my Tirpitz Build:-


A simple U bracket to fit the turret servo



Rudder servo mount




A bit of overkill perhaps but It was fun designing it and I can simply upscale it for larger servos

Not to be funny, but you could build almost true prototypical Liberty ships or X-Lighters using this type of printer. Printing the hole for the prop shaft is just the beginning, you could print integral motor mounts and even gear box casings with input and output orifices attached and aligned to the hull!

It is definitly the way ahead.
