  • With the amount of open bed, cheaper printers, a lot. Keeping them inside does not prevent them from entering the environment. As well we need to breath to start with, so airflow will take it outside. Add vacuum cleaning and waste disposal. Unless the plastics are trapped and melted into larger clumps. They get into the environment. This is why they are so dangerous.

    Even with enclosed printers. Unless very well filtered and some plan for disposal of that filter that prevents this. It’s just an extra delay.

    Some plastic types are better than others. And I honestly think development of thermo plastic replacements is better than stopping 3d printing.




  • Multihead printing is still in the early days.

    Agreed but then so was 3D printing as a whole 10 years ago. It is open source design started by Rep Rap that put us where we are now.

    Im a about to be beginner. Recently retired through disability. So finally have time to play with the subject. So yes, at some point I’d like to come back to you and take you up on your offer. ATM im saving to buy a Elegoo Neptune 4 Pro. And from there I have some projects to do then will start building my own design based on an open design I looked at in the past. (cant remember the name of my head)

    Thanks very useful. More or less what I expected but great to get confirmation. Humidity here is 30 to 60% averaging the higher end more often. So def need decent drying chamber.

    Yep, I knew the tent was more about retaining the heat. Just considered the hose a useful add-on. It is good to know you think that will be adequate as I could not find much online.

    Do you think mixing colours at diff layers will be an issue as long as I keep both rolls in drying chambers?

    Again, thanks for taking the time. It is fantastic to get some confirmations and advice from someone who has used the stuff before I spend what little cash I have.

    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.

    Nods nylon pA6 is much more heat resistant hence the choice.

    But the main reason is the bilge will get engine oil and diesel in it. These destroy other plastics over time. Abs and nylon or peek etc are the only long term options.

    Nylon is also stronger for mechanical parts IE small gears etc. While I can see me playing with that. It is not my main intent. Clips and specified mounting boards and frames is the main task.






  • Hard to be sure without knowing the exact tech developed. How efficient that is on defferent fuels will have an effect on how much effort is placed into gaining those fuels.

    Of course if real options exist the easiest to obtain fuel will be used. Capatalism will ensure that. Though honestly so would most other systems.

    But let’s face it. If mankind was able to generate plenty of cheap energy.

    The people profiting of limited resources supply now. Will not go away. And invest what they have in controlling supply. So expect some fairly unpredictable polical moves during the roll out.
