After 7 hours 18 minutes.................
Now, there's only the two track sets & turret to print!
DaveComment
-
A total of 15 hours printer time the AMC 35.............
The backs of the tracks need a lot of clean up to get a good fit on the hull, but otherwise not at all bad - scaled up to 1/35 from 1/56. Meanwhile the Monoprint is muttering in the background, printing a 1/35 Japanese Type 94 Tankette. This printer is slow, but since I restored it to life, it hasn't missed a beat - I haven't even levelled the bed in a month or so. The bed is rather small, so, if I print 1/35, I have to look around!
I look for tank models with separate tracks - i.e. hull, left track, right track, turret. It's easier to print tracks flat on their backs - it minimises overhangs and the need for supports - it often means that the back of the tracks has little detail - but these are against the tank hull, so it's not obvious

The Monoprice has just finished printing one of the tracks of the Type 94 & it doesn't fit the hull! The problem is, I don't know which is wrong. The model is scaled up from 1/100, and I suspect I dyslexed one of the scaling factors. I've resliced the models, but printing will have to wait until tomorrow. I'm surprised I haven't done this before very easy to do!:confounded:

Lazy day, looking on the 'net for models. I have found a Ferret ( I know Airfix are putting out a model in the summer ), and two models that have been produced in plastic, Tetrarch & M22 Locust - prices for these tiny Bronco models is around the £40 mark, I may print them, although the Locust has nasty tracks & suspension ( print wise )
DaveComment
-
I've printed out the M22 Locust & the Ferret in 1/35. I think the Locust running gear is about on the limit for my FDM printer - I'll put some pictures up tomorrow - I've tried various settings, but I think I've reached the optimum - if I want any finer, I'll have to drop the nozzle size & that opens a new can of worms.............
I've been fiddling with the Monoprice printer - I sat down & levelled the bed using feeler gauges, so now it is at it's best state. I'm determined not to waste the filament I had trouble with in the Anet & Sunlu. I'm using slow printing speeds & conservative temperatures, - it does mean extended printer times, but it is what it is.
I've found a suitably obscure model for this.................
I'm still not in the best of health, it's like a continuing dose of the 'flu - I find myself nodding off, whilst reading, or watching television. about the only good thing I can say is that my BP is pretty normal & my Diabetic blood sugar level is within it's normal range.

Pictures of the output from two printers - all in 1/35...............
Ferret - with supports still attached - the tyres look OK, but I would have expected a more off-the-road profile
Type 94 Tankette - a bit of clean up to remove those whiskers. Not a machine for the claustrophobic!
M22 Locust, with supports still on - the 30 calibre mg will need replacing - overscale and a drum magazine (?)
The Locust tracks printed on the Monoprice. Really more suited to resin printing! I slowed the print right down & each track took over four hours to print each. They are fragile & need a lot of clean up - I managed to break off part of the drive sprocket ( bottom right )
The track links are pretty well defined - even though they may look rough at this magnification!
Citroen-Kegresse P28 Armoured Car. I printed the hull with my troublesome white satn PLA - the Monoprice seems to be forgiving with it's feed - so that spool isn't wasted!
It's easy to find models on the internet, but to find models of lesser known vehicles is a bit more difficult, and of those that are suitable for FDM, even trickier. Sometimes what looks good, when printed looks horrible! I printed out a 250 mm liner & the result was really hideous! Trouble was the supports hid all the flaws, so not seen until the print had finished. You have to accept that certain things won't print - unsupported gun barrels for one!
As can be seen - all these prints need clean up, some more than others - it's very much like dealing with a limited run kit from a decade ago!
The output from Copper State Models is proving that resin printing can be extended to more than accessories. To produce an injection moulded model, you have to produce the CAD model & then have expensive injection moulds made, before producing anything. The resin printing process cuts out the mould making. At the moment resin isn't really feasible for large parts - like 1/32 aircraft wings & fuselages, but I can see that being overcome.

Ferret looks top notch Dave.You certainly are banging this stuff out.Hope the flu bug off soon.
Take it easy.

I found a nice model of a tracked excavator - the cab & the tracks are OK, but the arm I just give up on
No matter which way I orientate it, the supports needed are horrendous - I could cut it into bits, but that would probably increase the problems. Sadly this one I'll have to leave alone!!!

A little bust printing on the Monoprice......................
Charles Darwin - all of 60mm tall! Printed leaning back, so that any supports are on the rear, leaving the face clear.
A partial answer behind my health problems - dehydration! - for some reason I haven't been taking in enough fluids - I must drink between 6-8 glasses of water a day - at least two litres. I had a GP phone appointment on Wednesday and that was her conclusion, and I have had a bottle of water at my side for the last two days - making sure I empty it twice a day. Early days, but I do feel a bit better..........................

I decided I'd better process some of my printing - all 1/35 for this session. All of the parts need a lot of clean up - the models are 'kerbside' meaning that they are meant to be looked in a normal setting ( ie there's no detail underneath! ). You can't use power tools to grind, as this just melts the low temperature PLA - you have to use rotary cutters
They're supposed to be HSS, but at the price ( 20 bits for £7.19 on ebay ), I doubt it! They work nicely on PLA, but will blunt quickly if used on metal....................
AMC 35
Type 94 Tankette
Citroen-Kegresse P28
Mustela putorius furo
( Ferret )
Assembled with Loctite CA and primed with the dregs of an AK Olive Drab primer bottle - bad idea, as it was getting gloopy & I kept on having nozzle blockages. The primer has gone into the bin!
I'm leaving the printers alone for the moment, I'm spending too much time tinkering, and not enough at actually making finished models.
I'm a bit better, but still suffering with leaden legs - off to have blood tests on Wednesday, but I'm feeling a bit brighter and with it............

Some good work with the printer there Dave, pleased to hear you are feeling better.

At times my 3D printing can be bad for my health - specifically blood pressure.
I wanted to print a bust of the 'Night King', from Game of Thrones
I'd found a good model on Thingiverse
At first I inclined him backwards, to minimise supports on his front & back. This came unstuck from the build plate about 5 hours into the print. I then printed him upright - hoping that the plinth would keep him securely anchored. This one failed about 4 hours into the print!
As a last shot, I printed him on his back, accepting that there would be a fair amount of cleanup to remove the supports.
After 9 hours 45 minutes................Looking good - on inspection..............
No Idea what that blob is!
Oh - a support has come adrift, but doesn't look to have caused problems (!!)
Here he is, from the front - a handsome chap
Looks good - until you turn him round................
The support has failed on the back of his head - mildly annoying.
After 18 hours of printing, I'm not trying again - I may putty up the back of his head - but that would mean spoiling the satin white finish & needing a paint job. I'm calling this a partial success - as long as his back is to the wall, his injury can't be seen!
