1/35 Sd.Ah 56/57 Flak ammunition trailer (3D printed)

[Panzerwrecker]

So, how does it look under paint? Well not great TBH. The finish has not at all been helped by the rattle can primer, drying in places before it hit the model, I guess that must be the heat as the Halfords stuff usually lays down nice and smooth. As for the printed material there are a few printing line marks in places but only a few that will be obvious under the base coat. Mainly the vertical lines below the hinges on the nearside doors. There are a few horizontal ones on the lower panel, but these could easily be disguised as dents. The worst issues by far are self-inflicted. I haven’t cleaned up the support location nubs in far too many prominent places and I have damaged way too much fine detail. The front and rear panels have gaps where they meet the side panels and the body hinges on the nearside are nearly all missing detail, there are little bits on the edges of the ends of the roof that have also come away.

This is going to be a massive learning curve and I will now endeavour not to make the same mistakes with the second trailer. Laying down some primer on the outside of the main panels before assembly will be a priority. For now, all I can do is clean up what I can without further damaging detail and small parts and make the surface flatter for further paint layers. As for the damaged detail like the hinges that is going to be difficult to replace convincingly so maybe a few strategically places items will make them 'disappear'

Red circles are support nubs not cleaned up. Yellow circle shows how grainy the primer has dried. Orange circles are the holes for the padlock hoops that I have somehow missed to line up!


Yellow circles show hinge detail missing. Red circles show support nubs required more clean up.


Yellow circles highlight some vertical printing lines. Red circles show support nubs not cleaned up. I have started to sand and flatten the grainy surface. The horizontal print lines will be disguised as dents and scrapes. I'm not sure how i will address the vertical anomalies.


Some strange goings on with the paper shaper tarp material and a prominent chip out of the end of the curved roof.


The detail on the front chassis is looking good. Unlike the box panel connection gaps, I've ended up with:unamused:



Fortunately, the small details have thankfully remained attached.



TBH I'm a little disappointed it has turned out like this and I'm really itching to make good on the second trailer. I will persevere with more clean up and hope that I can get the surface smoother to get a decent base coat laid down. Levelling thinner will be required me thinks.

Still exceptional work Los, pity about the paint problems as you say. Don't know where you are but here the temperature has been much higher than normal , so may be that is the problem.

Los,
That is outstanding work mate. I am always impressed with the detail that can be achieved with 3d printing. Particularly impressive is the fine cross bracing in the interior.

Sunny Anglesey John and yes, I fear that is the isuue as rarely do I have an issue with Halfords primer auto rattle cans

Oops! ignore :tongue-out3:

Cheers Paul. Yes those partitioning grills do look awesome

Lovely work Los even with those little nuggly issues. For most modellers these issues are hidden with muck and paint but for perfectionists such as yourself I can understand your disappointment. The future doesn't look good for resin and rubber molding with 3D now...it's gradually taking over sculpting and figures too. Looking forward to your second trailer and dio.

Cheers,
Richard

Thanks for that Richard. I guess I'm feeling a little let down with myself seeing as it was all going so well. The printing anomalies I can deal with but those self inflicted issues I didn't see coming. Maybe thats the issue. Maybe I didn't notice them at all. Maybe it's time to face up to the fact that I would greatly benefit from using a magnifier.

I would hate to make the same mistake twice and it might very well be preventing progress with both my building and painting.

Either that or I'm on a backwards trajectory regards my quality of work.

We shall see

Ah the magnifier issue...that's the same with me. I tend to forego them during the stages before priming thinking that all's well and then see the horrors of my errors. :smiling6: I use reading glasses that need magnifying upgrades...can't seem to keep the focus for more than 10 seconds.
As for photography, the close ups can be scary.
So don't be too hard on yourself, we all get there at some point.

Cheers,

With the hot temps abating, progress continues. After some additional tidying up and with all the additional accessories prepped I give it another coat of primer. This time Mr Surfacer 1500 and it laid down much better.

The 3D printed detail really pops under paint but it also clearly shows a few areas that still need cleaning up. Notably the front face of both road wheels. These small nubs really are extremely difficult to see before adding paint. Thats my excuse anyway

The rear faces of the wheels will also need flattening to ensure the wheels mate to the hubs. CA glue has spilt through whilst attaching the individual wheel bolts.

As I suspected, adding additional accessories to the roof box has bent it a little out of shape so final attachment to the body will need extra care to align.

The detail on the ammo boxes and ammo is excellent. The loose 8 clip rounds fit perfectly into the open boxes provided. There are plenty of options to display spent rounds, rounds on clips, empty clips and you can even add individual rounds to the clips after painting if brave enough!

The other accessories are a mixture of plastic and resin items. They include the excellent Bronco Jerry cans, some Miniart oil and petrol cans and a 3D printed spare wheel. There is also a little stack of Sd.Kfz 7 track pads and some additional resin items like the basket and food cannister. The tarps are all made using VMS modelling paper.

Progress so far.

Simply incredible detail and such a superb build…keep it coming

[prichrd1]

Los,

Amazing result, even with the minor faults that you have highlighted - you can still have those on a mass market kit!!
I for one would be proud of that result :thumb2: :thumb2: .
Can you tell me what printer you are using?
I have been looking into them and have noticed the prices recently have lowered slightly.

Paul.

[Mini Me]

The detail on this model is magnificent!!.......I could never expect to find that in 1-87 scale,......someday perhaps. One can only dream

[Tim Marlow]

That really is a fabulously detailed kit, and you are more than doing it justice. The issues you mention are simply part of the learning curve required for working in a relatively new material. Now you know about them you will start identifying them much earlier in the build and they will become less of an issue. Stunning work.

Outstanding
