This equates to 1,32E for links needed for one kit. Of course you will loose some more, so lets say 40g. As it is 96 links par side, lets say 250 is going to be enough. The big advantages to me are, you can print them when you need them, so no waiting for an order to show up, and you can change the design if you want.ġ00 track links + pins require 13,8g resin. That's not meant as a criticism, just curious.įor a set I'd say $5 - $10 CAD depending on what resin you use. I don't mean the cost of the printer and software, I assume anyone that is going to go down this road will pay that money anyway, but not counting the cost of the equipment, is it cost effective to go this route as opposed to just buying aftermarket tracks. These look nice but my question, what did it cost you to print them. Nice! Will be interesting to see your progress and the final, assembled tracks. Not an issue with smaller stuff, this will be noticeable on bigger parts. In my case, i add 2.5% correction, to achieve correct printed part size. You must know, how much given resin shrinks while curing. Making tem partially conical, would also make life much easier.Īssembled tracks are fully workable, and fit Takom kits perfectly. All the rest, should be split in 2, and printed then, for easier assembly. In reality, i only need some 20 or so pins for spares, or ones inserted into guide horns. Surprisingly, over 70% turned out well!!! Level of detail is superior IMHO on printed tracks. Printed link is below kit links, therefore it might looks its tiny bit smaller, but they are equal, and even mate together well. Quickly primed link next to primed Takom track links. There are some places where parts look "de laminated", but that's due to lack of support, overall, success ratio is above 95% here. Heres picture of Panther track link mass production. But These parameters will differ from printer to printer, dont be afraid to experiment with some small parts, find what works for you best. Other setup features, i usually reduce lift speed to 65mm/min or less, bottom layer count - 4 is more than enough, bottom layer exposure ~8 times layer exposure is more than enough, more is overkill. Print step - 20 microns, although 25 is fine too. Printer used, Elegoo Mars2 Pro, Anycubic grey resin. I dont expect much from this, as thin wobbly unsupported parts is sure recipe for a failure I have also made print file with track pins. I would make additional file of flipped track link, so i have left/right links, this way, i dont have to care about reduced details on links pointing inward. My approach to this situation, would be horizontal printing for spares, vertical for main tracks. Drawback of such layout, is considerable reduction of parts per print, but it will print faster, than 1st example. This type of orientation will result superior print quality, but will also add to cleanup. As it will be vertical overhang, i have to either add more supports, or change track link orientation. Details are still there, but not as crisp as on top guide horn. Such layout allows me to stack multiple track links close to each other:ĭrawback of such alignment, is reduced detail on bottom track link horn. So i arranged links to be positioned vertically:Īs you can see, i have added connectors to support vertical overhangs, as they don't print very well. With ~200 plus track links required spacing between links becomes critical. The key of doing this, was fill factor maximizing on print plate. So i have added them manually in cad software, as i got more control there. As it is cad file of a part, it doesn't have supports. Print subject is Panther track link, downloaded from GrabCad:įile was imported, and scaled with Cad software. I will put my own files for download, and will share links here.įor a start, i will post some Track-Link print example. Including experiments, design changes etc, to achieve perfect the result. In this topic, i will share my 3D printing experiments. Sometimes small deviation is enough to ruin other vice perfect print. Resin choice, exposure time, step size, axis moving speed, part alignment, support layout and many more factors will influence your printing results. As with any technology, there are limitations. With growing interest in 3d printed parts, its time to start this topic.
