Oh and a new tool. Hopefully with a tutorial for us how to make nice 3d models.

Don't hold your breath Benedikt! 😁 (Besides I yield the floor to hendie when it comes to expertise in moulds and prints). If only part of the first print comes out I'll be happy as although it seems a relatively straightforward process to set up the object at a practical angle and have the required supports, I'm conscious that some of the smaller versions of the object may defeat the resolution of the machine. That's partly what I'm testing today to see what point it fails at, so time will tell.

 

Ok. The Elegoo's going to be chugging away all afternoon and there's only so long you can stare at the touchscreen on front of it before the excitement of watching the display refresh starts to pall a little. In and around this excitement I've been sticking bits on to Annie as were really at that stage where there's no reason not to crack on and make a bid for the finish line. The oil coolers are now in place under either nacelle:

49151912566_5d57844b36_c.jpg

For all the afternoon's additions, Gator's Grip has been the glue of choice as I've come to trust its strength and flexibility no end over the course of this build. Ailerons added on either wing as well:

49151416788_a353302ef4_c.jpg

Brutal way to clamp a turret into place whilst the glue sets but at least I know the undercarriage is strong enough!

Close up of the bomb aimer's window with masking removed:

View of the ailerons from above:

49152116152_7a3e20b4d6_c.jpg

Still the lever/mass balance assembly to put into that vacant slot beside the middle hinge of course ( as well as straighten those bent ends on the hinges themselves where my clumsy fingers have mauled them over the weeks: tribute tto GG that despite rough handling , the hinges have stayed in place so well). Not putting the rudder on until after the engine and props are fitted as too easy to bust off the aerial spike:

49151912611_0ffb4332e0_c.jpg

Speaking of props:

49151912676_e0fe60b4c3_c.jpg

Those and the spare Quickboost Brownings all got painted last night. (nicking just one of those barrels for Annie obvs...). The props were done in Alclad primer, Tamiya acrylic for the tips, and then sealed with Aqua Gloss: I've never used the latter before and although I'd been warned by others about its temperamental nature, have to say it went on smoothly and dried to a nice finish here.

 

Ok, I have to leave the studio now as the tension is becoming unbearable watching the printer.

Or is the resin fumes? :banghead:

Either way I'll post up results of today's test over lunch tomorrow and analyze any mistakes that I think I may have made in the setup.

 

Pip, pip!

:bye:

Tony

 

PS. Beautiful sunny winter afternoon here: one of the strays we feed - 'Chocolate' - is up on the kitchen windowsill giving it full Zen sunlight absorption:

Sheesh - you even fatigue test your models?

 

That photo reminded me of my time designing buses at Alexanders nightmare in Falkirk.  They used to tilt test the buses when the design changed.  The seats were loaded up with lead weights to simulate a passenger load, and there was a tilting floor - I think the only one of its kind in the UK at that time (?).  Over the space of a few minutes the double decker was tilted to ensure the center of gravity was acceptable. If I remember correctly the ALX series could get to somewhere around 42° - 45° without tipping over

 

Found a tilt test video on yewchoob (apologies for thread drift, but thought you may find it interesting)

 

 

it was quite a sight to watch.  Your brain would be telling you one thing and your eyes were telling you something else!

Oh, the suspence arises!

The suspense is over chaps!

 

Hadn't expected quite frankly to be in a position to post another update tonight, due to thinking that I'd need to sit down and look at all the things that went wrong with my methodology and explain to you why. As it turns out the Elegoo exceeded my expectations on an fresh-out-of-the-box print: that says a lot about the tool rather than the abilities of the operator.

 

One thing that is always bothersome about looking at video guides and tutorials for this printer is that the overwhelming majority of them show big massy lumpy figures or architectural structures being produced. I don't as it happens regard such examples as a particularly reliable our useful source of information for the kind of work that we do, hence the reason for this fantasy shape having:

1.multiple types of curvature,

2. overlapping parts close together

3. thin and thick parts

in order to to test to destruction at small scale.

 

Enough blather. Here's tonight's result, fresh out of the chamber:

49152856826_6974833af1_c.jpg

Diameters of those shapes from L-R:  28mm, 14mm, 6mm respectively. The holes in you see are drains to let the excess resin out of the hollow core shape.

I was - to say the least - pretty knocked out by performance on the first go.

As you can see below, the only places in which the print failed on the largest part was where I failed to support one of the vanes adequately when creating the support structure:

49153065067_73b005e990_c.jpg

The actual thickness of those vanes is 0.19mm at their thinnest point - essentially just under double the thickness of a sheet of A4 paper. On the middle 14mm diameter version of this shape, the vanes went down to is an astonishing 0.13mm in thickness - which seems to be the threshold at which the resolution of the printer fails. Amazing.

 

Trimmed out of the supports:

49153065082_93a13441bd_c.jpg

I've still a lot to learn about the best orientation to print particular shapes-  next time I might be tempted to print this flat against the surface to see if it reduces the number of contact points with the support structure between vanes. You can see a few of the stumps above where you cut that structure away - Elegoo provide a nice pair of sharp precision snips to clip the piece out, any residuals like those seen there are easily removed with a swish of the scalpel. I didn't bother cleaning the part up any further at this point to be honest as it's just a sacrificial foray to test the envelope.

 

Conclusions?

1. I'm unlikely to need to print parts as thin as those vanes thin on a regular basis so more than content that this tool is now 'required on voyage' for future projects. Quite simply it will let me be more ambitious in the kinds of structures that can be built, as a companion to existing brass and vacforming methods.

2. For the price, the resolution is outstanding.

3. Being able to pour unused resin back in to the bottle means you only use what you need.

4. It's not a replacement for traditional approaches, but provides a valuable extension of and enhancement to them.

5. You can print your own false teeth now.

I had mine down at 4, so it's all the more surprising the results were as good as seen here. One thing I did do on parts this small was to take the diameter of the contact points for the supports down from the default value of of 0.3mm to 0.12, plus reducing the depth of the contact point so it wouldn't stick out through the other side of the thin vanes. That seemed to work fine here.

PS. A lot of the online 'how-tos' - being American - only mention US cleaning products for tidying everything up afterwards. I used an initial bath of 95% IPA, followed by a swirl in this stuff:

and a final rinse in water seemed to do the trick with both the parts themselves, and the resin tray &etc.

That is … pretty impressive. 
 

I’ve had some experience of the final output of various 3D print technologies, and I have to say the finish you got there, Tony, is up there. Five years ago it would have been out of the reach of mere mortals like us. 
 

I know I could use this technology for all kinds of things. Sadly, my braincell almost totally rejects learning new software these days, so it’s the creation of the initial CAD that will prevent me wanting to invest. I shall continue to rely on others who are happy to take commissions and my money. :)

as an FYI - Shapeways won't accept a print with any wall thickness less than 0.3 mm - and that's using the latest and greatest technology, in theri super dooper material sets.  Cheaper materials are even larger wall thicknesses

I think getting anything to print at 0.19mm is a great achievement... maybe add in a safety factor and call the minimum 0.25 mm ?

As fine as this printer can go, I think you still have to account for scale effect - can the eye really tell the difference between  something at .3mm and another piece at 0.15mm ? 

As long as things looked "correctly" sized relative to each other I think it's fine.

 

Great first effort there Tony.  Just glad you like it after I touted its capabilities!

I am somewhere between you and Tony.  I m pretty confident that I will end up getting one of these 3D johnsons in the next few months, but for now I am contenting myself with learning Blender.  That’s why I’ve spent money on Ark’s boats from Shapeways; if I wait to acquire the requisite CAD skill, the printer and the inevitable test runs, it would risk pushing yet another build onto the Mañana Shelf, which I am trying hard to avoid (not least because that shelf is already crammed with Seafire 47, Walrus, Seafang, Sea King, Ark 5, Ark 2, Dido...)

As others have said, very impressive result there Tony. I have a family full of technical/artistic design types that are into 3D design and and such like, so I have access to a good knowledge base of products, but we have yet to provision a 3D printer. I think they are looking for Dad to take the next step - funding of course! About 5 years ago one of my sons helped me 3D design some replacement main-wheels for a C-47. The design looked the business, tread hub detail etc, but at that time getting them printed through shapeways way exceeded the cost of the original model. In the end I cast a new pair in resin from masters borrowed from a friend. My own background is in software, but like @Heather Kay, I am strangely averse to learn new products ..... a kind of reluctant boredom I think having spent years with the stuff! Time to change that I think.

 

The Anson is looking superb, and now of course after many masterclasses in brass-work, we will all now get to see you dipping your toes into the 3D modelling world .......... we are right behind you!

If we all had more time, maybe we could learn new products but we don't have enough time to build the stuff we want to build, learning CAD can only eat up more valuable time with the knock-on of building less. Choices ...choices.

It's a conundrum isn't it? Many people (no doubt including yourself) lead such busy lives these days that sitting down and learning 3D software on top of all their other responsibilities is just too large a budget of time to be able put aside. As you say, there are plenty of hungry young freelance designers out there willing to turn the job for a shilling or two.

Interesting info on Shapeways (why do I have the urge to write 'Milliways?' :laugh:)  and agreed on the last point regarding minima. Anything needing to be less than 0.3mm in thickness I'm likely to use brass for on the grounds of strength and sharpness of edge anyways but it was interesting to find a datum for the printer's capabilities.

We're in the last few innings of this build now and I'm anxious to keep momentum whilst avoiding breaking anything off if I can -footering and fettling this evening trying to get props and stbd engine sorted. It didn't, it must be said, get off to the most propitiuous of starts as I pretty quickly realized that I'd neglected to pay attention to mounting the props to the Cheetahs in a sufficiently robust manner. Tres idiotique. Out no point just trying to glue something one so risked the soldering iron to add some stubs on the rear of the props:

49159451796_4be2ecface_c.jpg

Well, it worked as you can see, but at the expense of blistering the bloody paint. My fault for not thinking this through so stripped all the paint off and resprayed.

 

After that diversion it was on to the main business of the evening. Hand on heart I was incredibly childishly nervous that I'd have fracked up along the way somewhere and that the engines wouldn't be in line with each other either from the front aspect or when viewed from above. After a little persuasion in the engine bearers and an anxious wait holding things in place while he GG cured, the stbd engine was not only in line but didn't show any signs that it would promptly drop off:

Seen from above there is a *slight* discrepancy in the 'nose' of the stbd engine being about 0.5mm forward of where it should line up with the port counterpart. I was initially annoyed with myself for not having caught that but then realized that as the port one if a plunge moulded resin copy of the stbd Engines & Things one, the actual nose of it is slightly shorter due to my less than competent moulding (you can poss. make out that difference in the shot above for yourself - the port one's snout is slightly squatter and with a correspondingly larger hole where the propshaft fits in). I reckon a slight collar of Milliput should be able to extend that port snout forward by the required amount without being intrusive.

 

Some paint damage to the metal foil areas due to handling and gluing the engine but am getting used to running repairs at this stage:

Almost there now:

Parts remaining to go on now are very few:

1. Pitot head under nose.

2.Lever/mass balance on top of each aileron.

3. x2 aerials on cabin roof.

4. Rudder

5. Cabin door.

 

Yes, the cabin door has been giving me pause for thought. Initial plans to have it fully open would seem to be contradicted both by the angle of the fuselage (pitched up) and resulting effect of gravity. I reckon the best compromise is to have it slightly ajar (so you can see that it's articulated as a separate part) but not unnaturally so.

 

At this point there could even be an RFI by next week.

Did I really just say that after 18 months?

 

:bye:
