I’m convinced Prusa and Bambu pricing is very simular; their printers just aren’t always an apples-to-apples comparison. When considering enclosed, metal framed, coreXY printers, the Prusa Core One can be purchased as a kit for $950, but the Bambu X1C is $1150. (I highly recommend the Prusa kit options for new owners so they can get familiar with maintaining their machine.) At the mini end, you have the same $200 difference, but in the other direction. The Prusa Mini+ kit is $430 while the Bambu A1 Mini is $220. However, these Bambu prices are currently shown as discounted and I’m not sure if they ever go up to their higher MSRPs. Therefore, I don’t like how Prusa is the only printer brand in this guide with an “expensive” warning.

Edit: Perhaps it would add more clarity to instead include the MSRP in parentheses beside the individual printers listed below.

I’m not sure what you’re woooshing here. If your saying that you were being sarcastic and you do recognize they were using affordable hardware, then that was understood. That’s exactly what I was responding to.

They used their Prusas and cheap filament to print pipe fittings that exceeded residential plumbing pressure requirements by 4-8x across the different materials. Filament cost was 3-17x cheaper than commercial fittings. Overall this study was a success. I think this price-point of printer hardware is a perfect match for the application. Any quality improvements from a more expensive “professional” printer would be wasted on these kinds of simple, low-precision designs.

Yes we are talking about home-teir 3D printers here. They used a Prusa MK3S printer and Prusa XL in this study. Also, they tested PLA in addition to PETG and ASA.

I don’t think it’s wrong to default to the kit. I wish more companies offered that option. If you’re going to be maintaining them, you need to be very familiar with how it goes together. However, I agree with your point if you’re buying in bulk. It will get really annoying to assemble multiple units back to back. Though, I believe Prusa offers discounts for repeat buyers, so the assembled option would drop in that case. Also, the Prusa Core is their latest release and we haven’t seen any deals yet. The Bambu X1C price I mentioned is the current sale price. MSRP is $1200. Going back one Prusa generation to the MK4, a fully assembled printer is only $1000 at MSRP. I still think Prusa and Bambu pricing is very comparable.

Regarding the MMU: yes, I’ve had two. I’d summarize them by calling them trash. They have both been collecting dust in a box for years. I eventually found that they were not worth the effort, but regardless, I don’t believe that old accessory has any bearing on the printers themselves. If a Prusa printer did have any substantial issues on release, I would at least be comforted by the fact that you won’t be stuck with it. The upgrade kit options, extending from the early MK models through to the MK4, and now to the Core One demonstrate that commitment. I can’t think of any other manufacter doing something similar.

E: cleaning up some typos.

I believe the only thing Prusa is withholding from open-source is their PCB designs as of the MK4 and Prusa XL release.

I’m curious what you’re referring to when you say Prusa doesn’t have the best track record on initial release. I started with two MK3s at work, upgraded them to MK3S+s, and now to MK4s. I didn’t have any trouble along that upgrade path and I was always an early adopter. We also have a Prusa XL. If you are still on the MK3 model, perhaps you haven’t had much experience with their newer models. However, the MK3S is six years old now.

Regarding cost, Prusa seems very comparable to Bambu for similarly speced printers. Specifically, looking at printers with an enclosed print bed and metal frame, the Bambu X1C is more expensive at $1100, vs the Prusa Core kit at $950 (assuming your comfortable assembling it yourself).

At home, I’d sure love to have a Voron to tinker with. However, for a print farm, I wouldn’t consider anything but a Prusa these days.

From what I’ve seen, middle of the road 300 mm Voron V2.4 kits are around $1300. I believe the lowest I’ve seen was around $950, excluding printed parts (which the same company was selling separately for over $200). When I tried compiling a BOM with self-sourced high quality parts, the total reached over $1700 before I gave up on that idea. Where have you seen $600 kits? If these are still available, I may consider one. However, I’m hesitant to go with a kit that may have lower quality components. Personally, I’m really excited for this new Prusa and will probably pick up a kit once they are available. Unless, of course, Vorons are really that affordable.

A Voron V2.4 for cost of this kit ($950 / 1050 EUR)? Sure buddy.

This is not their first core XY and they redesigned the hotend with the PrusaXL and MK4. As far as I’ve seen, they are the only printer company using a strain gauge in the hotend for bed leveling, that they also use for detecting clogs while printing. Also, the new printer’s price is comparible to the similar model from Bambu with a metal frame and enclosed print bed (X1C). And, as you pointed out, they always maintained the same serviceability (I’ll add upgradability). Therefore, I definitely don’t agree that they are playing catch up.

You mean scrambled porn, right?

From your source:

{The upper flow is faster and from Bernoulli’s equation the pressure is lower. The difference in pressure across the airfoil produces the lift.} As we have seen in Experiment #1, this part of the theory is correct.

Sure, it might be more complicated and there are other forces at play. Also, top and bottom air molecules may not reach the backside of an airfoil at the exact same time, but that doesn’t diminish the effects of this pressure differential on lifting force.

That lift explanation is innacurate/incomplete. While there may be some equal and opposite forces depending on the angle of attack, the primary reason for lift is due to Bernoulli’s Principle. Airfoils have a rounded upper surface with a longer path for air to take, relative to the underside. This requires air to move at a higher velocity over the top, and since A1 x V1 x P1 = A2 x V2 x P2, pressure over the airfoil decreases. It is this pressure differential that creates lift.

In regards to aircraft, Newton’s third law of motion applies to thrust from a propeller or jet engine.

To listen to…

I must say I don’t like the idea of a social-credit-score bot.

Regarding your implementation, I saw the summary of your own comments elsewhere in this post and I noticed all the annotations were on upvoted/blue segments. Other summaries you posted focused more on negative/red segments. Would it be possible to enforce a minimum of 1 or 2 from both categories?

Also, would you be kind enough to read my tea leaves? Am I an acceptable citizen of the Lemmy community?
