Generally speaking there are 3 physical ways of joining any part. 1. Form fit --> dove tails, snap fits, bow ties, typical wood joints, etc. 2. Friction or force bond --> screws, wedges, magnets, etc. 3. adhesive bond --> all types of glues, welds, soldering and melting It is best to combine them for example use a dove tail design to create a from fit for a strong connection and additionally use glue if the connection has to stay that way or wedges if you want to disassemble it some time later. Try to avoid using only one connection type and always remember the 3 connection types.

Using pins to align if gluing works great! Also, using puzzle joints like bowties works ok too! Great video! Tapping holes is great when your hardware is too small to print threads, or when you don’t have enough space for heat-set inserts! Forcing threading can change your part tolerances! Tap tap tap!

After several tries and fail with heated inserts, I found it much easier to use screw insert on fill length to long screw, for example, M3 30mm. Then using pliers hold the screw vertically and apply heat using solder to the top of the inset and push it into the plastic. A screw will prevent plastic from getting inside the insert hole. To extract the inset put a long screw into it and heat it. The plastic around the insert will melt and you will be able to pull the screw with the insert back

@stevenstone6010 2 жыл бұрын

Friction welding is another method that can be very useful in some situations. Hold the two parts together, and use something like a Dremmel tool to spin a small piece of the plastic material (either a segment of fairly thick filament, or what I do which is to print a small peg in the same filament) against the joint area. The friction of the plastic rapidly rotating against the printed parts will cause them to heat up and fuse together. It takes a little practice to do it well, but it can be a nice alternative to adhesives!

@@aa1589you should design in finding features. Simple holes on one part and a tapered pegs on the other. Or if peg is not printable, then holes on both and print the peg separately. Prusa slicer can also automatically generate them while splitting a model, though you might prefer to do it in CAD for more control.

There are many joints used in woodworking that work even better for 3D printing. Clever geometry that slides together, then holds super strong. For example, the classic dovetail can be modified to be even stronger and prettier for 3D printing.

From skimming through this, I have to point out two things: 1) I wholeheartedly despise the adhesives I've used, i.e. superglue. I don't know what superglue you're using, but the _various_ brands (and types - liquid and gel) of superglue I've used are by no means permanent and snap very easily. For a Colonial Marine breastplate I printed, it was like that Don't Break The Ice board game, and I wound up having to use thermoplastic to make backing plates and then gluing those over the lines between printed parts to make it more sturdy overall (and the glue at least worked for those, but it wasn't strong enough to hold individual parts on its own). 2) I'm positively _astonished_ by the fact that you didn't bring up the use of a soldering iron as a possible means to connect two or more parts, because after I gave up on the superglue and thermoplastic backing plate combo (though I might use backing plates since they actually work VERY well), I tried out this one video's technique of taping two parts together by their edges and then using a soldering iron to melt the plastic of both parts together. Just right from the get-go, they're 1,000,000x more durable than superglue (as in I did three drop tests of a prototype helmet before a piece broke off, whereas with superglue, all of the pieces would be all over the floor the second they hit the floor), and with a backing plate put in, that would only further reinforce them. That said, this was a pretty decent video and I like how it pointed out several things I hadn't thought of before, while also outlining what to keep in mind with doing those techniques.

Nice video! Very well structured! I wonder what are the options with resin prints? Printing the screw directly in the print should be even easier as resin printers have even finer details, but I'm not sure how strong are resins vs metal bolts for example - what's the wear'n'tear with usage. Hot inserts don't work with resins unfortunatelly :/

@Itsdirtnaptime 11 ай бұрын

I haven't tested this, and maybe you have something that works. You have a few ways to make threads in machining. Cut taps or form taps. (There are other ways, but they are not relevant.) Essentially what you are going is form tapping. For an example. A standard 1/4"-20 home would be drilled to .201" before tapping, with a cut tap. This is literally cutting metal away. The form tap just pushed metal into itself. And as you will be doing with the threads. That hole would be filled to .228" before tapping. Moral of the story, perhaps look up a form tap drill chart. Try those size holes for when you want to use a bolt to form the threads. I hope this makes sense. I don't think 3d printing and machining concepts are too far different.

@robertpelland5649 Жыл бұрын

With all due respect, brass inserts might be your favorite way to join printer parts, but you are using the incorrect inserts. You need those that have a smaller protruding smooth section, that matches the diameter of the hole, thereby making the insertions exactly centered in the hole, and not based on the way your iron is held.

I find when I put threaded inserts in, the plastic gets into the threads themselves and then I have to carefully screw and unscrew the screw several times into it trying to loosen it out. This sometimes means overwhelming the bond on the outside and causing the whole thing to start spinning

Two more offhand that didn't make the list: Zip-ties. Make aligned rectangular holes in the two parts. Optionally two more holes, or a channel if near an edge, for the return loop. Optionally inset a gap for the head to sit. Prusaslicer cut now has an option to generate a matched pin and socket, either with the pin attached to one side, or printed separately.

Another way I could suggest doing it as well you could use either hot glue or say a pen to fill the hole. Make keyed holes. #\ /#. - top layer with - where part is split #/ \# - bottom part my #### When the two parts are together the upper cone meets the bottom. So you have a cone and an inverted cone. The inverted cone is on the bottom part. Then when the part just put together simply fill the void with hot glue for temporary and or plastic from a pen for more permanent connection. The advantage of this is then you could send off the surface and you never know the thing existed. Easy to put into the design. Just to circular cone is accessible on the surface so it can be filled. It's also way to secure a lot of internal components if you want something solid. You put in a mesh interior not for support etc but just pretty much empty space. Then fill it with resin

@Wyld1one 6 ай бұрын

Another thing with using a resin pills you could have the locking parts hooked into a loops on the interior so when the resin finally flows around the inside and cures there's no way to take it apart

@Wyld1one 6 ай бұрын

It's an idea I saw from when you're trying to lock two pieces of stone together you have a keyed surface that on it that you can chill out you pour metal into it it locks the two blocks together. Then you also have the other situation like pouring concrete with rebar. the bars there to hold it together but in this case you do it leave space for the 'rebar'. When you fill the resin in later, it locks it all together. Theoretically you could use an injection molder to do this part

...stripping threads (or breaking of heads of screws) is not unique to 3d printing. One of the easyest ways to bork your stuff, is lubricating your screws (with something like WD40) before tightenjng them to specified torque - as without the usual metal on metal friction eating away at the force created by the torque, you can output 2x (or more), and break stuff.
