Title: BSC 2018: Burgundavia's 3-wheeled, 3d-printed truck (Feb 8 - 1st print)
Post by: Burgundavia on January 13, 2018, 11:52:35 PM
Quote
The 1956 PANG Saddleback truck is the only 3-wheeled truck that didn't use a motorcycle engine ever mass produced. Designed by the Pavlovian Automobilistî Nøcktremmik Gåenstphabrik (PANG) in Pandolvia just after the Second World War, the PANG Saddleback was designed as a mule-replacement in a country famous of mule-breeding. Originally a work truck capable of carrying heavy loads on Pandolvia's narro mountainous roads, the truck spread into Africa in the 1960s, usually following Soviet or Costa Guano forces fighting in the brush wars of that continent.

(Drawing Credit Jason Torchinsky/Jalopnik 2017)

The idea and the drawing cribbed from this awesome Jalopnik article https://jalopnik.com/an-imaginary-car-from-an-imaginary-country-1976-pang-s-1819248813 (https://jalopnik.com/an-imaginary-car-from-an-imaginary-country-1976-pang-s-1819248813). I changed the date from 1976 to 1956 to fit better with the games I play.

As I just got a 3D printer (an Ender 2) and am teaching myself 3d modelilng, I will be creating what amounts to a model kit and then painting that, all in 1:56 (28mm) for Africa 1960s.

Why is this ill-advised? Who in their right mind would design, let alone mass produce, as 3-wheel truck? They are tippy as hell and putting a single rear-wheel where the weight is even dumber. And then you go and split the cargo compartment in two.

Work so far: I have built (and rebuilt) most of the back of the truck. First draft:
(http://warbard.wirelizard.ca/files/PANG1956-Jan13th.png)
EDIT: Fixed image link

I didn't like the height of the middle section, so I completely rebuilt it and the current version now looks like this:
(http://warbard.wirelizard.ca/files/PANG1956-Jan14.png)

Their have been a few questions about how to build things. Here is the middle section of the PANG with all the parts exploded out and grouped:
(http://warbard.wirelizard.ca/files/PANG-middlesection.png)

As you can see middle section is made up of 6 parts - 2 of which are "holes" that cut away the solid pieces. Each of the parts quite a simple shape, but when you combine them together (group them in TinkerCAD terms) you essentially do unions and differences to end up a final object

So I've started work on the front. Why major annoyance with TinkerCAD (over real CAD programs such as even 123d) is the ability to loft, sweep and extrude. Essentially take a 2d schematic and turn it into a 3d object. I am going to have to creative to build the front end of this beast, which is lots of curves with curves.

(http://www.warbard.ca/files/PANG-Jan15th.png)

I am really not a fan of the height to width ratio right now. The source material has a bit of a conflict on this. The front profile makes it look like a VW Kombi (taller than wide) but the rear 3/4 view is wider than tall. Shall have to experiment with both to see what looks good.

How will you both print it? Do you print it on your own machines or do you get a third party to do it? I’m (personally) not sure how good home printers are these days. I’ve seen some prints (even ones that are supposed to be professional) come out with ingrained lines!

I bought an Ender 2 last month. Its board promptly cooked itself, waiting on a warranty shipment by modeling this stuff. The commercial stuff is too expensive, tbh. And given I am designing this, I know I will go through a few test prints to get the quality I want (which likely involves redesigning parts)

Today's progress - not much. Been rebuilding the rear roofline to match the curve. Getting the look I want has been frustrating, so I turned to the side panels and started in on those. Not really happy with how it is looking but that is great thing about 3D modelling - I get a few more tries

Inspired by Scurv, I laid out the truck for printing today.

(http://www.warbard.ca/files/PANG1956-Jan31-PrintLayout-400x326.png)

I chose not to break out the rear section or the bins right now, which is why the weird little truncated tire. I want to see how the whole thing prints before I invest too much more time in tweaking, as I might have to do some major structural changes.

There are also a few other missing elements including the biggest, an interior, but also small details like side mirrors and the like. All of those again can wait until after I have printed my first draft

A closed cab sliced just above the wheel rim and the bottom half of that cut flipped over on the print bed would give a good result.

How does this work exactly, i.e. why would a standing print turn out better? Knowing so little, I don't know the effect of the different arrangements. Is it because it will be in fewer pieces and therefore be more likely to align properly?

Theory is this: the most common nozzle size is 0.4mm, but usually you print with 0.1mm layers. That means you can get finer details vertically vs horizontally (in theory).

Ok, resliced. I did a second cut at the window height so I didn't end up with a giant overhang for the roof line of the front of the cab.

That roof will have a lot of visible lines on it. It might be better if you can print it vertically.

I dont mind a kit that I would need to assemble, that way I can tinker more freely.
Just so long as it is not a file as I do not have a printer.

That is what I was thinking - offering up either the file or a printed kit for you to assemble as you desire.

this is by far the best 3d work in the comp. (Not saying mine and Beefy's work is horrible, but this is inspired.) I am more than happy to give advice to the beat of my ability in order to get the best print results. In fact I will be mentioning this to Eureka Nic next week as he is starting to take an interest in 3d and this will appeal to his sense of whimsy.

Thanks! I have been working on a side on another whimsical vehicle, the Helms Bakery bread truck. I looked at it for this, but given it was mass produced and succesfully served for 30+ years, it really didn't fit the theme

As for seeing it printed, the replacement board is sitting in customs in Richmond. Hopefully it will clear early next week, as time is ticking down rapidly.

And we have our first print:
(http://warbard.wirelizard.ca/files/DSC_1698-400x300.jpg)

So I accidentally printed with brim instead of skirt. Oops. I was tired (the print ran for about 3 hours overnight). Also the green colour was my wife's choice - she wanted it for sailing parts, so I am using it for test prints and things that will be painted. I have a nice sedate grey for final projects.

As scurv and others who 3d print will notice, my 3d printer is far from dialed in on quality. Given that this truck was the second successful print I have ever 3d printed, I am not surprised. Notably I am missing a part cooling fan and my belts need tightening (and replacing with metal core belts). It is also under extruding quite a lot, plus the Creality version of Marlin is ancient. I have a better board arriving, likely not here for the end of BSC.

Assembled(ish), it looks like this:
(http://warbard.wirelizard.ca/files/DSC_1699-400x300.jpg)
(http://warbard.wirelizard.ca/files/DSC_1700-400x300.jpg)
(http://warbard.wirelizard.ca/files/DSC_1701-400x300.jpg)
The Model A is a Lledo truck, the unpainted figure an Infinity Ariadna and the painted figure a Copplestone Back of Beyond Chinese.

So the truck is too big. I am going to shrink the final product by about 25-30%. Also, I have a tonne of small changes to make to the truck to make it print half-way decently. My short list includes
* Thickening parts to print correctly. The fenders didn't even print and the back corners of the cab don't have enough support
* Breaking up the roof and printing it vertically (I knew I was going to have to do this, decided to print it like this anyway)
* Removing or making some details bigger
* Redoing the bumpers entirely - they didn't even print
* Recutting the cab up - the very top most piece didn't even print correctly

I also didn't print the boxes, I know they will need work. I am out of town for a few days on vacation, so lots of time to tinker on the next draft before I am back next week to showcase that.

Brim is what you see on my print. The part sits on the bed but is surrounded by a solid plastic.  A skirt it a couple of lines of plastic laid on the bed around the part, but not touching the part.

Spent some time working yesterday and today to clean up some of the printing issues I found with my first draft. First up, some pieces were a bit too thin to print properly.

Back corner issues:
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.
(http://www.warbard.ca/files/PANGFeb8CornerErrorTinkerCAD-400x336.png)
When you bring this into Cura to slice it for printing, the problem becomes obvious.
(http://www.warbard.ca/files/PANGFeb8CornerError-400x273.png)
The solution to this is to thicken the back wall of the cab, which I did by adding a flat piece to it:
(http://www.warbard.ca/files/PANGFeb8CornerErrorTinkerCADcorrected.png)
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.
(http://www.warbard.ca/files/PANGFeb8CornerErrorcorrected-400x320.png)

I also looked at fenders and the top of the windshield, which I wrote up here:

It looks good. Like you said the roof needs re orientation and thickening those parts like you have done will solve most of the other issues. Maybe just check your bed is level as possible as well. Cant hurt.

Thanks. Haven't done a bed level in a few days, need to do that. Apparently new Marlin will be able to auto bed level using the nozzle and TMC2100 drivers - which I am waiting for in the mail.
