I have never used a 3d printer. But have done a little research.
Be great if someone could confirm my intention is sane.
I have loads of Linux experience so my plans relate to open source all the way.
First off I am brassic(poor). So looking cheap all the way. My brother and I have a tiny narrowboat we are refitting. And plan to use the printer for stuff within the boat.
Due to this printing PA6 to go in the bilge is important. (Diesel and water bad for most other plastics)
As we are both vision impaired and old. The idea is most of the electrical mountings etc will be self designed and painted to make future access quick and easy with our rapidly worsening vision.
So my plan. I am looking at a elegoo Neptune 4 pro.
Because it is cheap but great value. Uses kipper. And seems easy to modify as I grow in use. Also supports temps needed for PA6 etc.
But I will need an enclosure to work with PA 6 and a dryer.
Dryer is cheap not an issue.
But I’m thinking of a tent enclosure. Some good well insulated ones on amazon for £50 with hose to vent out smells.
Will one of these tents be suitable for keeping temperature stable while printing PA6. And can anyone offer other advice for cheap solutions to make this easy.
On a related novice front.
Gue to the vision. One of the projects is to print mounting boards for din rail fuses etc. The idea being to mix colours.
Ie flat surface faces from and back in white. The the inner support fram in a bright colour. This will mean holes to support thumb screws etc for easy low vision future maintainance. IE easy to find the pre set screw holes.
This plan means I can swap colours when printing layers so should be easy without over (for me) briced multi head printer.
But can anyone share experience with doing this with nylon. IE how dose delays in printing the layers while swapping filament t effect the linking of those layers.
As I say complete novice o the actual doing this so any advice will be helpful.
Polyamide is a huge pain to work with. It absorbs water like hell, warps, needs high temperatures, and post-processing is hard.
Did you consider using PETG/ PCTG? They are also very strong, don’t absorb water nearly as much, are easy to print and are UV resistant.
Do you already have experience with CAD modeling? Most programs are Windows only, and the only “good” software I found is Onshape, which isn’t FOSS.
PA6 nylon is the best for strength and chemical resistance. As some parts need to survive in bilge water for a decade or so. Diesel oil will rut them. Nylon plastics are best for this and heat resistance from hot engine. As parts will be used their as well.
Yeah I know it is one of the hardest to work with. Hence the tent and dryer comment.
Would be fantastic if someone with experience in it can tell me if the tent solution is good enough.
Worst comes to worst all have to build a frame enclosure, and it is only a few parts where nylon is required. So I can learn.
The fact that the neptune is able to print at the temps needed is one of the reasons I am considering it.
As for cad. I have lots of experience with blender. While it is not designed for true cad. It is very capable of the levels I need.
Also, FreeCAD has grown hugely since I last looked into it. So way more practical to use if I get into anything more complex.
