As I am fairly new to 3D printing, I am learning a tonne about what not to do. One of the biggest issues I have discovered is that things that look good in CAD can look absolutely terrible once printed, given the resolution of the printing or the limitations of FDM 3D printing. Today I wanted to talk about three different, but similar errors I made: making a part too thin to print correctly.
Back corner of the cab
First up – the back corner of the cab. As the backside of the cab is curved, it thins quite a bit at the very back corners.
When you bring this into Cura to slice it for printing, the problem becomes obvious.
The solution to this is to thicken the back wall of the cab, which I did by adding a flat piece to it:
Once you bring that into Cura, you see that the narrowest part is now at least 1mm thick, so the piece shouldn’t be so weak.
The next piece I tackled was the fenders. They were originally 0.25mm thick, which means that they were just over one layer thick when printed at 0.2mm and only two layers thick at 0.1mm. This meant they basically didn’t print at all.
The solution to this problem is two-fold: thicken the fender up to 0.5mm and also only print at 0.1mm (considered Fine quality).
Top of the windshield
This is actually entirely my error. I made the windscreen and frame around it taller than the sides or back of the cab. This meant when I cut up the model to slice, the top of the windscreen disappeared. Oops.
The new printer board for my 3D printer finally showed up, so I got to printing the first print of my 1956 PANG. It was less than a full success. As you can see in the pictures below, I have a bunch of work to do.
As can be seen on the build plate, a bunch of details didn’t come out right – the biggest of which was the top of the cab for some reason completely failed to print correctly. I also accidentally selected brim intead of skirt, so I had lots of cleanign to do.
The sides of the truck aren’t very smooth, and a bunch of the finer details simply didn’t print.
So what next? First of all,my printer needs some upgrades:
A part cooling fan (the Ender 2 lacks it by default)
Belt tighteners (and the belts replaced with metal-core of some kind)
A more modern Marlin (the firmware that runs the printer)
A lot more tuning
On the truck, the first thing I am going to do is shrink it by 25 to 30%. It is too large for what I want. Then I need to some work on the model itself
Thicken some of the walls so that they print, especially the fenders, which didn’t print at all
Clean up some of the smaller details, possibly removing them for now
I finally got around to laying out the 1956 PANG for the first printing. As you can see from the pictures below, I am trying to remove the need for supports which will mark the surface of the final print.
I chose not to break out the rear section or the bins for initial printing. I likely will in the final version, as it will speed up print time and make it cleaner.
One final note: I am certain that there will be tweaks needs to be this and I am missing things, namely an interior and side mirrors to start.
Build Something 2018 continues and I have been pretty quiet for the last week. Part of this is because I am waiting on the warrantied printer board, so motivation is low. Also been busy with other things. But today I kicked myself into gear and go the first printable draft done of the 1956 PANG. Take a look below (the red rectangle is 32mm high and is there for reference):
Well, Build Something 2018 is well underway at Lead Adventure. You can follow all the entries, including at least two other 3D printed things, over on the subforum.
And what of our 1956 PANG tricycle truck? Yesterday saw a lot of work on the back end. As of two days ago it looked like this:
I really didn’t like the aspect ratio of the truck – height, etc. So I completely rebuilt the back end so it was taller and thus looked narrower:
Today I started working on the front end, which is a lot harder. It has a lot of curves with curves, so it going to be a real challenge to do well. I am not overly happy with the look (too wide and squat) so might rebuild the front. Here it is in exploded view.
What I love about modelling this way is that if you don’t like something, it is trivial to rebuild it. Play with the ratio, etc.
I posted my Round 1 entry for the recently concluded Lead Painters League 11 (run over on the awesome Lead Adventure Forum) way back in mid-April but never got around to posting my other entries.
So here they are all at once, including Round 1 again for completeness sake.
Note that I repeated one entry in a later round, so there are only nine entries here instead of ten. My Round 2 entry, Patients of Ward 13, were re-run as my Round 9 entry after the English Civil War musketeers I’d hoped to run didn’t get finished in time. Interestingly, the Patients lost their initial round but won their re-appearance, which is unusual as repeat figures rarely win LPL rounds in my experience!
There’s captions for each photo with more details, including manufacturer info for all the figures.
Buttresses and a double row of foundation stonework have been added with pink styrofoam insulation cut with a new Xacto knife. I used scrap card to create a small jig to keep the angle of the front of the buttresses the same across the fourteen buttresses around the outside of the church. The buttresses are roughly a quarter inch wide, two inches tall, and about half an inch deep at the base of each.
The front door is card with planks scored into it, with more light card for the hinges and handles. The door arch is more pink styrofoam. Inside the church I’ve added an interior wall of 1/16th matt board on the tower end to hide the tabs where the tower walls slot into the end wall. That’s had some added detail with matt board and card, and the door was done with offcuts of coffee stir stick wood and card.
All of the styrofoam was glued down then carved and textured after the glue had dried; I used a ball of tin foil to add a stone texture, then my usual knife-and-pencil stone carving technique.
Priming & Painting
The whole building got a coat of black paint as primer. Rather than the default grey stone that I always seem to use I took some inspiration from churches I’ve seen online from Shropshire county in England and decided to do mostly reddish stone with some grey stone used as accents, similar to the Cound Church of St Peter
I started with brown paint drybrushed heavily on, then a fairly light grey paint, and finally a drybrush of red oxide/burnt umber. I’ve done a bit of edge highlighting so far, but will do more and might yet do another paler drybrush over the whole building to pop some more details out.
The capping stones on each buttress were done in dark grey then drybrushed a paler grey, as was the arch around the main door. I might yet do more stones in grey, just to add some variation to the building. I also glued the porch walls and front down, and added more strips of styrofoam for the foundation of the porch.
Both the main roof and the porch roof got covered in Warbases’ very nice lasercut slate tiles and primed black like the rest of the building. So far the main roof is painted more or less the same as the rest of the building, with an extra grey drybrush to pop the texture a bit more and make it look a bit different from the walls.
The porch comes with MDF panels for the roof, but they look quite thick so I cut a strip of light card the same size, folded it, and glued it into place. Before gluing the roof down I added strips of card against the stone wall to hide the slots where the MDF roof panels should slot in; they’ll be painted to look like lead flashing eventually. As mentioned, the porch roof got more of the Warbases lasercut slate tiles, and will get bargeboards on the front edges eventually to hide the edges of the slate.
Up on the roof of the tower I doubled the thickness of the walls with matt board, then put down a wooden floor using styrene plank sheet, with a roof hatch from a bit more styrene. The upper edges of the walls got a bit of GW Liquid Greenstuff to help disguise the line between the MDF wall and the matt board additions, and painting is in progress.
Still To Do…
The outside edges of the base has a layer of fine scenery grit – coarse sand – glued down and mostly painted black; I’ll paint it up dark brown with a bit of a drybrush, then put various kinds of flock and turf around.
The porch still needs work, mostly paint, and a bit of detailing on the roof. The tower roof also needs painting, and I’m not entirely happy with the colours on the main roof.
Inside is still the big job. The Warbases kit comes with solid lasercut windows that look good from the outside but will make the accessible interior look a bit odd. I might use square grid plastic mesh – the same stuff you use in screen doors – to fill the windows, with inside walls of more matt board, like I did with the inside of the wall between the tower and church proper. Still, with the exterior done including scenic groundwork I’ll be happy to put the church on the table and put finishing the interior off for a bit!
Warbases started doing vehicles in lasercut MDF and cardboard (greyboard) a few years ago and I was intruiged right away; a lot of 28mm vehicles are fairly expensive or (especially for World War One, Russian Civil War, or other early 20th C gaming) simply don’t exist.
It took me a while to get around to ordering any of the vehicles, but I now have a Pierce Arrow truck and an Albion truck that I’ve built, and I’m pleased to say these are really nice kits, great value for their cost, and quite easy to build!
The Peasant Cart
I also picked up Warbases’ Peasant Cart 2, which is part of their Carts & Wagons line, listed separately from the Vehicles line. This is a straightforward little model, about 20 pieces including the wheels, and produces a nice solid piece of wargaming scenery. It’s called a cart, but it is a full four wheel wagon.
Assembly and painting didn’t take much time at all, maybe half an hour. I used a random grubby wash of green-grey over the whole wagon, added a bit of pale grey for the insides of the wagon, then did a bit of edge highlighting with a grey-white mix just to pop some of the edges a bit. I’ll probably glue some straw (cut from manila cord) down to the inside of the wagon just for a bit more easy detailing.
The wagon is big enough that two or three figures on 20mm bases could fit in the bed of it, although it’s too narrow for 25mm or larger bases to fit flat.
The Pierce Arrow is a relatively small truck, with room for two or three figures in the truck bed. The Albion is quite a bit larger, with room for 6 figures on 20mm bases or 3-4 figures on 25mm bases in the bed.
Each truck comes as a couple of small sheets of MDF and an even smaller (business-card sized, roughly) sheet of greyboard card, with roughly 30 or so parts per vehicle. The instructions are photo-illustrated PDFs on the Warbases website, which does mean you can check them out before purchase. It sometimes takes a bit of peering at some of the photos to figure out which part is being fitted where, and as always I highly, highly recommend carefully dryfitting everything before you start adding glue!
One thing I noticed and appreciated about both trucks and the wagon is that any part that isn’t unique is actually identical to any corresponding part – the sides of the truck beds are identical and interchangeable, for example. Most parts aren’t labelled or numbered, but this nice design touch makes it hard to screw up the build process. Warbases has also put on-sprue/on-sheet photos of the parts of all three of these kits on their website, which helps sometimes with keeping track of parts.
The Pierce Arrow truck took me maybe an hour to assemble and paint to the point you can see in these photos; it’s got a bit of detail painting and cleanup left to do, and maybe some more weathering, so these are fast kits to assemble and get onto the table. I stopped assembling the Albion at the point you see in these photos so that I could paint the undercarriage before adding the wheels and fenders, as the Pierce got a bit cramped to paint with the wheels in place and the Albion has fenders on all four wheels, not just the front. I’ve also skipped putting the cab roof on the Albion for now to make painting the inside of the cab less painful.
The Pierce Arrow has been basecoated dark green with a black roof; I’ll do a round of highlighting (mostly of the edges) and there’s some detail areas like the wheels, headlight, and front grille left to paint. I haven’t decided what colour to do the bigger Albion; possibly dark grey or tan. Both colour schemes will do for either military or civilian vehicles of the era, especially in the chaos of the Russian Civil War!
The fenders, incidentally, are the only really fiddly bit of these kits. They’re lasercut card (greyboard) that you have to bend gently and then glue to an MDF inside piece to get them to hold the needed curve. Neither fender on the Pierce Arrow is quite right, although both are acceptable given the battering such fenders would take on the real vehicles! The instructions from Warbases say to bend the fenders over a pen or the handle of an Xacto, but doing this caused the greyboard to crease for me. I had better luck gently pressing the pieces against the pad of my thumb with another finger and gently flexing the card into a sort of curve that way.
That quibble aside, these are great kits and I’m sure I’ll get more eventually. They’re very sturdy once assembled, well designed for easy assembly, and it’s nice to have such an inexpensive source of vehicles for Early 20th C gaming!
I headed over to Vancouver for my annual pilgrimage to Trumpeter Salute again at the very end of March. My girlfriend and I decided to tie it in with a road trip the week before to visit my folks a few hours inland from Vancouver and her folks up on the Sunshine Coast just north of Vancouver, which had the affect of making sure I was tired even before Trumpeter weekend started!
Regardless, it was a great show. I’ve been going for eight or nine years now, with one or two gaps, and there’s a number of folks I only ever see at the Trumpeter Salute show every year that I look forward to reconnecting with and seeing what spectacular gaming projects they’ve been up to.
This year we started off on Friday night with some 15mm WW2 Eastern Front action, leading a German mix company to a really marginal victory against the Russians. No photos of that, unfortunately, which is especially sad as Troy runs a spectacular looking game and each vehicle and infantry stand is a tiny work of art!
Saturday morning we started off by borrowing Martin’s son’s Star Wars Lego collection to run a good sized Star Wars Lego Battle of Hoth, complete with AT-AT, snowspeeder, and a fierce Bantha! Luke in his snowspeeder managed to bring down the AT-AT, but when he went back out to rescue the pinned-down Wookie squad, Darth Vader managed to capture him (and Han!) in the middle of the snowfields.
Saturday afternoon we ran a 1980s air war scenario based on the Iran-Iraq War. The Iranians had all American fighters, including the F-14 Tomcats the Shah had purchased before the Revolution, and the Iraqi Air Force had then-new MIG-25 Foxbat fighters, straight from the USSR. Unfortunately for the Iraqis, Iranian luck and high tech American missles meant it rained Foxbats and parachutes into the Persian Gulf all afternoon!
Meanwhile, this spectacular Vimy Ridge game was being put on by the White Rock Gamers.
Sunday I ran a Pulp Alley game with six players. There were three groups of fishmen, a Miskatonic University research team, a team of human cultists, and a mad scientist all competing to find or recover a lost Treasure of Dagon! Lots of action and pulp hiliarity ensued, ending in the cult leader blasting multiple other characters with terrible occult power and preventing the recovery of the Treasure.
The Lead Adventure Forum runs a great painting contest about once a year called the Lead Painter’s League. I’ve participated before but not for a number of years now, but when LPL11 was announced a while ago I decided to get back at it and enter.
LPL was originally conceived as a way to help participants clear their stockpiles and lead mountains of figures, so the requirements for small groups of figures – the minimum entry has to be five figures – and relatively loose theme allow you to paint whatever you feel like. There’s bonus rounds with slightly more specific themes on the first, fifth, and tenth round but they’re intentionally loose as well. This year’s bonus themes are Tribes for Round One, Ship’s Crew for Round Five, and Big Brother/Little Brother for Round 10.
I was able to get ten rounds worth of figures together, including satisfying all three bonus rounds, just from my stockpile of figures, in classic LPL style!
For Round One, Tribes, I used a family group of cavemen (cavepersons?) that Bob Murch of Pulp Figures sculpted. There’s a grizzled old shaman, an older woman, a young mother with baby on her hip, a teenage boy, and a younger child. I think they’re some of Bob’s older sculpts and it looks like he’s taken them out of circulation at the moment – which means we might see resculpts sometime soon!
