Hey G'day people,
Ok I am not new to CnC I have built my own after having purchased a kit and finding out the things I didn't want and the things I did want. Once I found out what I wanted my build was relatively easy.
But but but,,,,, I wanted to make a particular stirling hot air engine and just fell over by chance on an article.. as per link for a 3d printed hot air engine... yup I'd never seen one before so I purchased the plans ahead of a 3d printer as I can always use the same plans for my CnC anyways.
Reprap-Windturbine: Stirling
So I have no idea if spending $300 gets you nothing or $1000 is the same as spending $300..
I asked the seller of the stirling plans what type of 3d printer he used and he said a 3d prusa.. means absolutely nothing to me atm.. so Dr Google to the rescue points to eBay and we have the following..
2017 3D DIY Upgraded Full Quality High Precision Reprap Prusa i3 DIY 3d Printer | eBay
and another similar (to me they look the same)
Print 6 materials Geeetech Reprap Prusa I3 Pro X 3D Printer MK8 shipped from AU
the above is used by some to print R/C planes..
Before I go building one myself from scratch or purchasing one for bigger $$$ are those two printers good enough to do the job of printing that Stirling Engine.
The thing that killed me when I bought my first CnC kit was it was terribly slow, a job which now takes me 3/4 hours to carve was 12 hours.... so my question is how Fast or Slow are these 3d printers..
If printing that Stirling Engine is a 20 hour job Im already not interested and would want to invest in something quicker. If the resolution of the above printers is the print looks like a 150 year old wrinkled skin Im also not interested.
I understand and have seen High Resolution printers in the many thousands... I'm not after perfect more to the point looking for something Reasonable and not aww gawwwd that looks orible for the first comment ..
I nearly dipped in for a liquid resin 3d printer which was selling for 1/3 its retail price... I went cold when I spoke to the guy selling ... Printing was High Res .. tick... Printing was abysmally slow XXX ... It used proprietary cartridges for the resin with a chip of somesort cost of cartridges was XXXX so that went of the shelf quickly.
In Short is there any reason why I wouldn't/shouldn't buy one of those printers considering the cost is pretty minimal and would they do the job..
Once I have one I guess the rest will come..
Cheers and avagreatday from the colonies downunder..
