Should I get a 3D printer?It would come in super handy when making brackets and such for my projects, as trying to machine small metal parts out of literal scrap with mostly worn out hand tools is pretty tricky.But I have Four main reservations:The brackets I make often have to take a fair amount of stress, are 3D printed parts strong enough?I suck at any kind of computer modeling. I only know how to shape things physically with my hands, and there's _still_ no way to directly translate that into a computer.I live in a house with many other people. Will noise and smell be a significant problem?And finally, I have very little income. Are the running costs very high?I know I can look this stuff up, and I have, but all the articles in the world generally don't compare to just asking someone who actually does it.

@OpenComputeDesign Oh hey, I can answer some of these!A 3D printer is definitely a handy tool to have, but it's far from the wundermachine a lot of articles make it out to be.- The PLA filament I use is fairly strong, but does get brittle over time, especially under load or in a humid environment.- You can do a lot with simple sketches and extrude operations in freecad, which is fairly easy to learn imo.(1/2)

@OpenComputeDesign- PLA and PETG filaments have fairly inoffensive odours, but I've heard ABS really stinks. Sound is very variable, depending on what kind of printer you get and how fast you run it. Mine is quite loud, so I never run it overnight.- Filament is kind if expensive, but if you don't use much and seal it in its bag when not in use, a little can go a long way.Hope this helps :)(2/2)

@OpenComputeDesign I don't think running cost are high, the most expensive part is inital acquisition. What still is a problem is that for big piece it requires a very long time to print, so a dedicated room with good air passing is really a good thing, withing a garage by exemple.Even good PLA has bad emanations and those are not very healty, so air should be cleaned. Avoiding it in a sleeping room is a must.I would anyway recommend to pass by a fablab first, to get informations and sometimes you might even get hand on free 3D printers that have never been finsihed or that went broken and need repair or are just unused, for a tiny price.

There's a little smell with PLA, but it's not bad. I've only used PLA. The same, almost zero experience modelling, but I made a bit to help me install some blinds last night (using Tinkercad) and it was helpful. The blinds were pretty light. I have busted pieces before, particularly small pieces. I printed an x-wing fighter where the end bits just fell off, but it's a weak point. My Ender 3 Pro was around $350CDN back when I bought it from Ender. I think I spent around $200CDN in PLA (lots of spools) and another $100 in upgrades (auto-levelling, new plate). It can get a tiny bit noisy, especially if you run faster than 50 mm/s. I wouldn't want to have it in the same room I sleep.

@OpenComputeDesignMaybe? It really depends on how much printing you are likely to do realistically. They're expensive if you only do a few things then leave them to gather dust..Out of the box my ender 3 could wake the dead but I replaced all the fans and motors with silent ones and it was fine.. cost as much as the printer to fix though.The other thing would be reliability, I abandoned the idea because you'd spend all day levelling the bed only to have the print fail again. @andypiper

@OpenComputeDesign You can hang a surprising amount of weight off of well-designed 3D prints. You can watch videos by CNC Kitchen, especially this one, for some examples: https://www.youtube.com/watch?v=ycGDR752fT0You don't really have to learn to CAD to benefit from 3D printing: there's _tonnes_ of models out there you can print and use.Noise can be significantly reduced. CNC Kitchen did a vid on that too.Filament itself is not expensive, though the printer itself can be, depending what you buy.

@OpenComputeDesign This is the start of a thread.The important thing to know about 3D printing is that you don't need to be a "creator", many people have 3D printers and never touch the design side. It is possible to have a printer and just print the designs of other people. The 3D printing community is a huge advocator for #opensource. We encourage people to take our designs, with credit and attribution of course, and remix them, print them and use them as they like.The first important thing to focus on is the licensing that the original creator has defined. This defines what you are allowed to do with it, how you may change it and whether you may commercially sell it. If it is just for personal use, most of the time it is not a problem, but if you want to commercially sell these prints, please speak to the original creator first.@3dprinting #3dprinting

@OpenComputeDesign I've not used it myself, but apparently carbon fibre infused nylon filament can produce very durable parts. The only downside there is you need a printer that gets hot enough for nylon and you'll want to replace the extruder head with a stainless steel one, as the carbon fibre wears down the metal a lot faster than normal filament

@OpenComputeDesign Your use-case sounds a lot like mine. I originally chose between getting a printer or a drone.I am a creator and always had the problem where I built circuits for my own personal use, but could never get brackets, enclosures, mounts or whatever that made my projects attractive and still practical.When I first got my printer, I already had 3D design experience, quite a lot of it. But designing for 3D printing is different from other mechanical and metal designs. You need to think about how the printer works, how it will be constructed, strength and other mechanical properties.If you aren't familiar with 3D design, but want to learn, nothing will stop you. The #Fusion360, #TinkerCAD and #OpenSCAD communities have thousands of tutorials on #Youtube and they are some of the best communities I've ever been part of.@3dprinting #3dprinting

@OpenComputeDesign The #Reddit 3D printing communities are also amazing and very supportive. If you have a specific use case, I am subscribed to most of them and can easily point you in the right direction.Then you also get the #Discord communities created by most #Youtube creators. If you find a creator printing things and projects you like, most of the time they have a Discord server with like minded people.@3dprinting #3dprinting

@OpenComputeDesign In regard to strength. It depends on what you want to do. You can share some parts you made I can give you some advice.The strength of the part is dependent on the material you use. PLA is a soft material, but very easy to print. It is usually the beginner material, however some professionals still use it because it is cheaper in some regions.Personally, I print with ABS. It is more difficult to print with, but has a higher thermal resistance than PLA, which can become soft in direct sunlight. It however needs an enclosure and has some other problems, but it is quite strong.Then you get PETG, which is like the in between. Most people move to it once they get the hang of it. It has the ease of PLA, but more advantages of ABS.Then you get TPU, the flexible filament. Some people never touch it, depends on your use-case. It can be difficult, depending on the stiffness you want.@3dprinting #3dprinting

@OpenComputeDesign Then you get Nylon. Now we are moving to the more difficult materials.Nylon needs higher temperatures, my printer for example can't print it because I can't reach those temperatures. I also think it needs an enclosure and is notoriously frustrating because it absorbs moisture very easily, which ruins filament btw.Other more engineering materials aren't worth mentioning here, because they require expertise materials, but you can easily find lists of 3D printing materials.https://www.matterhackers.com/store/c/3d-printer-filamenthttps://all3dp.com/1/3d-printer-filament-types-3d-printing-3d-filament/https://3dinsider.com/3d-printing-materials/@3dprinting #3dprinting

@OpenComputeDesign The strength is also dependent on your gemoetry. Of course plastic isn't as strong as metal, but do you really need that strength?Sometimes metal seems very strong, but plastic will also work, the metal is a lot stronger than what you actually need.Then we also have some tricks in the 3D printing world, we manipulate our gemoetries. We print in different orientations and use different temperature settings. Here are some good videos on the topic:https://www.youtube.com/watch?v=fbSQvJJjw2Qhttps://www.youtube.com/watch?v=YzZqJtEOWjEhttps://www.youtube.com/watch?v=chCmwSdQzcEhttps://www.youtube.com/watch?v=3-ygdNQThAshttps://www.youtube.com/watch?v=M3bwJx8ZkMAhttps://www.youtube.com/watch?v=bG8dlxTX3AIhttps://www.youtube.com/watch?v=uAoZCpXoPWohttps://www.youtube.com/watch?v=z3aUGmfnmIgAl these videos are made by #CNCKitchen, a great #Youtube creator that does many experiments.@3dprinting #3dprinting

@OpenComputeDesign The noise and smell of a 3D printer is dependent on the material and printer you use.As mentioned before, ABS and ASA has a strong smell, PLA doesn't. Some wood filaments can also smell very bad I've heard, but never printed with them.The noise of the printer is dependent on the printer, fans and speed you print at. Mine can be as soft as a normal desktop PC or be louder than the average volume I watch #Youtube videos at. It depends on the speed that I print at. People mod their printers, add quieter, smaller or bigger fans. I have a nosier fan now, but I added extra cooling fans because of my enclosure.The enclosure also muffles the smell and noise, so it depends.@3dprinting #3dprinting

@OpenComputeDesign Just a side note. Until now I have been speaking about #FDM printing, you also get #resin printing, but that is more for other stuff like mini figures.Personally I don't have one, have any experience, but know a lot from the content I watch online.It requires more workspace, safety equipment and tools, and I invite an actual user of resin printers to please advise due to their experience.Personally, I don't think resin printing is the thing you are looking for@3dprinting #3dprinting

@OpenComputeDesign Finally, the cost.You can spend anything from $100 to $10000 on a printer. It is like drones. You get what you pay for. I would personally stay within the $300 to $1500 range for a hobbyist printer.Filament cost depends on the filament you use. I use ABS, it is more expensive in other regions, but for some reason I get it for almost half the cost of PLA.It also depends on how much you print. I print a lot, for me. I go through a spool in about 3 months, which is about 1kg. Other people can print a spool out in a few days with a single print.It depends on the size and density of your prints.@3dprinting #3dprinting

@TavisB @OpenComputeDesign I lost my smell and taste completely after COVID, haven't been able to smell mine since.Makes things difficult when printing and building circuits. Before I could smell a short circuit, now I just see the smoke coming from my breadboards or feel that my chips are red-hot!

@OpenComputeDesign @TavisB It has been two years, hasn't gotten better, learned to live with it. I avoid stuff that has an awful smell and taste, some stuff has a pungent smell, and then I just set reminders for food, ovens, irons and anything that can burn. Oh, and a smoke alarm on my printer.

@OpenComputeDesign Do you have photos of the sorts of things you want to make?In contrast to everyone else responding here, my experience is with resin printing. I do print structural things, including mounts for microcontroller boards. Suitability depends on exact application. I often use nylon-infused "tough" resins.You can also use prints to make molds to cast things in more durable materials.Safe handling practices recommended, including good ventilation.

@Stark9837 @OpenComputeDesign @3dprinting I also have no 3d printer yet. One of my wishes is to print ag pipe fittings. The common Philmac fittings we usually use often have me assembling a chain of adapters etc and they’re not cheap. It’d be great to make each end and some intermediate tube as a single item. Strength concerns me.

@cs @Stark9837 @3dprinting I don't think I've ever worked with ag pipe, but I have had to do a fair amount of plumbing. And oh god the fittings and adapters. I had a spot once where I had to bring two 1" and a 3/4" iirc drain pipes on opposite sides of structural beams together and feed it into a 3" run. I just about had a panic attack when I saw how much the parts for my solution cost.

@OpenComputeDesign Apologies for the delayed response. I had to run off to an event.I think you could get workable parts at that scale from either SLA or FDM printers. FDM might be a little easier to wrangle in the environment you are describing (less concern about toxins in your living space).Stuff like that should be pretty easy to model in something like FreeCAD (FOSS) or Fusion360 (commercial but, free for hobby use).

@OpenComputeDesign @Stark9837 @3dprinting Aye, that's often my pain point too (not to mention just ftting the required combination of fittings into a space occasionally). And of course every joint is an opportunity for leaks and tightening difficulties, and the threaded ones eat teflon tape regularly.I've certainly had a few threaded fittings fail under mechanism load (generally not the water pressure, which is mostly static load from tanks higher up the hill). It's be good to print exactly what I need if they could be made suffiently string and water tight. And can a 3d printer print eg BSP threads with sufficient precision?I'm mostly using this brand: https://www.philmac.com.au/products/
