That’s where your math are wrong.
The A1 isn’t two time faster than the Mini it’s just bigger. So yes you can put more parts on the bed but the production time will be very similar. The A1M Swapmod will only take 5min more because of the build plate swap.
So for the same production output the power consumption between the two will be really close. And it will probably in favor of the mini (Mini ave. power 80w vs 95w for the A1).
And you didn’t took in count the human labor in your price. And it’s the most expensive post ^^’
In his example where he is making 10 objects per A1 mini plate, wouldn’t a A1 produce a given quantity in half the time since it can print 20 vs 10? Isn’t that two times faster?
I think he meant “I set up both A1 minis” otherwise his math is wrong.
No the A1 can’t produce parts faster than the Mini. Same speed/Accel, same volumetric speed.
So if I can only put 10 parts on the plate of the Mini and it takes 4 hours to print and it will take 8 hours on the A1 to print 20 parts.
In that case, it make a little bit more sense. But the power energy cost still would be in favour or the swapmod. (Minimal idle time, bed almost always at constant temp).
And for the maintenance thing. The A1M swapmod will wear faster but only because it will produce more parts. And you can easily swap the swap mode in less than 1 min, put on another Mini. And do the maintenance. Virtually zero down time on the production line ^^
Sorry if we are all a bit annoyed that you are coming onto a community forum with 400+ positive comments and leaving a comment saying that we are all wrong and that something we are all excited about is completely pointless. You are totally right on this
Another forgotten benefit is no delays due to cooling and heating.
There is no downtime for cooling down and heating up between prints as the SwapMod solution removes the plates when they are still hot.
Without a SwapMod the user has to be at the printer exactly when the print completes, wait for it to cool sufficiently to safely remove the parts without cause deforming them and then starting a new print, with bed-level and getting back to the correct temperatures.
Here’s a little chart I made to visualize it, I included 1xA1 since I erroneously thought it might have some benefit. I bolded the manual plate swap times.
Wow, thanks for making this effort. A while ago I started coding a web-tool, which calculated such things, but have not finished and left it halfway. The idea was that you enter your print-job, needed amount of parts and your availability days and times. The tool calculates the printing cycles while changing plates manually and compares it with the automated setup. I hope I will find time to finish it one day. The formula to calculate the output of regular printer setup turned to be more challenge than I initially expected (at least for me) and I was to lazy to write an algorithm function.
But as you already noticed the calculation for the automated setup is quite easy and this is also one of the benefits IMHO.
Cost of the setup
A1 mini combo + swapmod + 8 smooth plates
350 + 70 + 825 (20 during the sales) = 620€ (580€)
Vs
2 A1mini combo + 2 smooth plates = 750€
Added advantages:
I don’t need to have 2 spools for each colors or respool
I don’t have to dry 4 spools but only 2.
Reduced the human labour. Ideally only one human intervention per day. So at least 6 times less than a dual printer setup.
I had zero lost on 450 parts, all the parts look amazing.
if the printer brakes or needs maintenance, I can just swap the A1M with a new one (plates, swapmod and AMS are still good). 620 + 200 = 820€. But the production is not affected where if one of your printers is down the production output is divided by 2.
