Hello there! Newbie to actually using crafting tools beyond “theory”, so I’m at the precipice of “fine, I’ll do it myself” and outsourcing the fabrication of items.
I will be needing to print out 18 copies of what is essentially a 100x120x40mm box; the cheapest online option I found quoted me at ~$11 a pop, so, $200 to get that done.
The class to learn the FDM is $100 (I thought it would be cheaper than the resin, but I just checked and saw I was mistaken); on top of the makerspace fee of $75/mo puts me at ~$175 as well.
That means the deciding part of my equation depends on expected pricing for filament.
I know members are responsible for consumable materials; looking at the Prusa MK3S+ says I’ll need a 1.75mm filament, and there are all sorts of price variations there… so in short, I guess it’ll be better to just hit you with a list of concise questions:
TL;DR QUICK N EASY QUESTIONS
What software should I use to model the designs for 3D printing; I know that you can change the density of “solid” prints, but I’m not sure if that takes place in the design phase or is a setting you tell the printer, etc. (attempting to manually create “thin” walls exponentially increased design complexity and I imagine plays hell with the 3D printer’s automated routines for creating supports and such).
How much modification of the 3D printer should one expect to do? I see that with the MK3S+ you can change nozzle size, but the manufacturer specified “Layer Height: 0.05mm - 0.35mm”; does this reasonably extend to layer width? (I might be mis-applying a term, but “kerf” error by any other name)
How expensive do personal prints end up being; or rather, what’s a good metric to determine the cost of materials? This in part goes with an answer to question , is there a way I can figure out how much filament will be used in a print ahead of time? Is it as simple as saying “volumetrically, it should be 100mm^3, but I’m setting the infill to only 25%, so therefore, it’ll be 25mm^3”
is there ASMBLY preferred filament for the machines?
I think that about sums up the questions. A good few of these I imagine would be answered in the 3D printing class; but hopefully you can’t fault a guy for “trying (to learn) before buying (the class)”, y’know? I’d like to imagine joining would mitigate a lot of the upfront costs of just doing it all myself, but I’ll likely also need woodshop safety/lasers class; so without materials and just through classes alone to get oriented with ASMBLY practices, I’d be about $315 in the hole, which is a bit of a bummer considering my project is so technically simple.
Essentially, it feels like I’m doing something wrong when my back of the napkin math has my “board game box” idea winding up to be so expensive any way I cut it, and I’m not sure if these prices are reasonable or not and that I just need to shift my perspective and scale
Thanks for your time in advance!
