I am looking to buy a 3D printer for my son (and for myself too). We want to print, not tinker, so it should be something that gives great results right from the start.
Can you guide me to a sensible choice?
My first choice would have to be the Prusa MK3S Plus but it is outside the price range I am shopping for, except if I buy used – would that be bad to do?
Realistic choices:
- €380 used Prusa MK3S+, with 10 days printing time
- €400 new Prusa Mini+
- €250 new Ender 3 V2 Neo
Criteria:
- High quality, no hassle. I want to print, not tinker.
- Preferably (semi)assembled.
- Auto bed leveling.
- Auto error detection (filament, power, etc.?).
- Budget up to 600 EUR/USD including extras, excluding filament.
- Speed is not important.
- Size is not important.
- Must not be cloud-based.
Questions:
- Surface?! Smooth, os satin, or textured? (Why) Should I have more than one kind?
- (Why) Do I need an enclosure?
I’ve owned 3 printers, all cheap. For what I spent fixing it upgrading them I could have bought a Prusa. More than saying my next printer will be a Prusa, I can say that I actually have one on preorder.
Also, I will never buy a fdm without a bed leveling function. No, it’s not necessary, but if you want a low frustration printing experience, it is - in my direct experience - essential. Prior to having abl I would keep an eye on every print start. With abl I send a job to the printer and check on it when I get around to it.
Go for the used Prusa MK3S+. People used to pay a premium for assembled and tested printers. As long as you can get the printer to you without being banged up in shipping it’s good. Really shipping would be my biggest concern.
I have a MK3S+ and it just prints. I print for my Etsy shop and don’t really feel the need for a backup printer. I have 1600+ hours of printing on it. In that time I’ve had one nozzle clog and one blob. I do a little dust filter on the filament so i don’t often get clogs https://www.printables.com/@Fohn23_807562/collections/641537
I’m totally happy with just the smooth sheet. The textured sheet is supposed to work better printing PETG but I’ve been able to get perfect PETG prints on the smooth sheet using windex as a release agent.
Speed is not important? Are you sure? Is this your first printer? I though that too at first, but trust me, you are most likely going to want speed more and more once you get going. Also, 3D printing is pretty much synonymous with tinkering unless you have some sort of business model in mind, but if you do… (see comments about speed).
My take, go with lightly used mk3. Market is primed for two reasons - first, in US at least there is just less of a sellers market lately for anything used and with recent Mk4 release people are looking to sell to upgrade.
Wish you luck with whatever you end up with and have fun and don’t be afraid to tinker!
If you can trust to that used mk3, 10 days is nothing, I would go for that one. My average print time is 6h so it means someone printed like 40 prints and I could do that in bit more than a month of average use. They are made for way more hours.
High quality, no hassle. I want to print, not tinker.
Sadly, there is some thinkering involved even with $2k+ machines. Getting prusa over ender is like paying more to dodge desing flaws, faulty parts and crappy support, its not buying plug&play machine. Its still hobby grade machine. Most important is to have loads of patience and prepare for learning advanture, but thats super fun IMO. Once you master your machine, after you experienced many failed prints on it, you can then proceed to plug&play workflow.
IMO, assembling your first printer is highly recommended, it will help a lot in the future. Auto bed leveling is pain that you need only if hardware is not built in low enough tolerances, so if you can get printer that prints good without abl its even better. Speed is super important, print time is quite huge on even fast printer. You can expect 12h print for some 15x15x15 cm part with 0.4 nozzle and 0.2 layer height. And thats quite optimistic guess, some prints take days to finish. You will always balance between speed and quality. Using 0.8 nozzle can push 4x more flow with proper hotend if quality is acceptable. So its not just about axis movement speed or acceleration, its quite important how you model your parts and how good you are with your slicer. Using different infill or model orientation can be a big thing sometimes.
About size, smaller machines are more rigid but can print smaller parts obviously. Since printing is super slow, smaller is better for cheap machines imo, but kinda limiting if you want to print long flat parts for example. Prusa mini have cantilever X axis, so it has to be much smaller or use much higher cross sections for same rigidity as mk3. Rigidity is actually a limit for your max accelerations/speed without losing on quality.
Also, I wouldnt put filament sensor and power features on the list. Lot of people disable them due to issues they cause, it sounds more usefull than it is. 1 kg of filament is like 24 hours of print time and its not hard to guess if you have enough material for a job (slicer will tell you how much you need). If you lose power printer will stop and probably make scarf cuz heated nozzle will heat everything around it. If thats not on the visible part, you can messure your print and continue from there, or just print top part and glue them together. Its quite hard to continue without noticable mark afaik, and UPS is probably the right way to deal with it. I lost power 4 times in 7 years, found that a lot, but was lucky cuz printer was on idle every time.
Start with PLA since its the easiest to print and suits most people. PEI sheet with no enclosure will work easy, but make sure A/C or window is not blowing air on one side. Enclosure is still amazing, it protects printer from dust, isolates some noise and it makes environment temp more stable which is super important, especially for materials like ABS. It can also help in keeping your filament dry, especially if you want to print PETG (filament drier is recommended and almost must have for PETG anyway). Its safe to start without one, but deffo plan to get enclosure in the future (even cheap ikea lack will do).
Just as a heads up,you claim to say that speed and size is not important, but trust me, speed and size is always important for 3D printers. Minimum size (except for unique situations) should be around 8"/200 mm cube. For speed, I think the Voron kit was (one of) the fastest ones out there. Now your budget won’t allow for one of those printers, but they are a good way to compare the ones you are considering.
I only have experience with the Prusa Mini+,and I have had it for 2 years now and have barely had to maintain it. But, still, the only printer i’ve owned.
I’d go prusa mini at this price point. It’s a really reliable little machine, and easier to build than the MK3 and others. Enders are really not worth your time, trust me, I had one.
I just upgraded from Monoprice Select 3d (not what you want) to an Ender 3 S1 and am super happy. I’d recommend the S1 over V2 for you if you think you might want to ever print flexible filament
I got mine for $299 USD on Amazon
You’ll want an enclosure if you want to contain smell or if you want to print in ABS (of any size, as drafts will fracture the print before it cools)
If you live near a Microcenter you can get it for even cheaper: https://www.microcenter.com/site/content/specialoffer3dprinter3i.aspx
This deal is not always limited to new customers. I bought a month or so ago on sale at this price and I shop there regularly.
I’d recommend the Ender 3, I have the Ender 3 Pro v2 I believe, and it’s been very reliable and worked right out the box. I got it on sale at micro center for $100 USD, I’ve heard they go on sale fairly regularly.
Assembly is easy. It doesn’t have auto bed leveling, but the adjustment knobs are easy to use (look up some videos on using a piece of paper and moving the X and Y location of the extruded to level).
It doesn’t have error detection, but I’ve seen some mods online that use an Arduino for this. Even with error detection I don’t think it’s recommended to print unattended due to fire risk.
It comes with a removable flexible textured print surface with heated bed. This texture helps with print adhesion by keeping the part being printed secure while printing. And for fragile parts, you can remove the print surface and bend it to help remove the part after printing is finished. This has worked nearly flawlessly for me, compared to earlier printers where people would use painters tape/glue sticks/etc to help with bed adhesion.
An enclosure is a nice addition, but not really necessary unless you’re doing large prints or really trying to push the boundaries of what you can print. The idea of the enclosure is that it keeps heat in to prevent the part from warping as the extruder moves up along the Z axis. For small parts the heated bed will provide enough heat. You can build one out of plexiglass and 3D printed brackets, or an ikea coffee table (look online for examples).
