    Nothing wrong with Solidworks. I'm moving from a K&E drafting machine and skills learned 60 years ago with pencil and paper. It was time to learn 3D modeling and Fusion looked like the latest program. Besides, the price was right (free) for a hobbyist.

    Yes I agree with both you guys, I do have an old copy of SW but I never did get to grips with it (only because I didn't have a 3D printer) - the backup with Fusion is massive and yes Lars is good (even with his unusual New York/Danish accent!).

    My first obsversation on 3D printing is that it's like watching grass grow or paint dry! and I do realize that each pattern has to be destroyed in lost PLA casting.
    However it's extremely interesting and very good for the one off type experiments we tend to do.
    The traditional patterns and casting methods such as Neil uses are far from finished yet, they do need a bit of space (which I don't have) to operate, but I think still rule supreme when you need to do more than just experimenting.

    Of course a good printed pattern (smoothed up) and with built in draught (draft to our US friends) could still be a possibility for use as a permanent working pattern!

    Has your printer arrived yet Ken?

    Nope, but the polycast, plus pla, abs & nylon filaments are on their way. BTW Will, what slicer programme do you have? Eg, Simplify3D, Cura, Reptier etc.

    Haven’t gone thru this in any detail as yet, but it looks to be a fairly comprehensive guide (there are quite a few to look at though):

    There's a joint in the US called Ransom & Randolph who look like suppliers of investment slurry, but haven't found anyone in Oz as yet. Problem is that one doesn't want a 300 + litre tank of the stuff, 20 lit would be just fine.

    Back to 3d printed, patterns and coreboxes, I think it was Katinas who printed a comprehensive set of transfer port (plus other bits) coreboxes on his Zortrax printer. They looked pretty good.

    Just going through all the basic stuff, and Cura is doing well (there's millions of settings which I'll delve deeper into as I grow more confident) - just printed out a lot of crap I concocted in Fusion 360 - soon I will be able to make proper simple patterns and I hope to find time to try casting again this summer, so long as I'm not moving house for a while yet!

    You sure aren't slowly wading in at the shallow end Ken!

    Jeez, I hope you aren't right Will, what if I can't swim ????

    Yes, but you've had a little bit of experience - I've had none! that's why I had to get a cheapie so that I wouldn't lose a lot of money by stuffing a more expensive machine ie by trying to sort out any flaws ( inevitable in any machine - I like to doing that anyway) and learning what not to do at the same time! - trial and error, best way to learn, sticks in your mind!

    Already got a couple of problems, I stuffed up the USB input by pushing the plug in through a badly misaligned access window in the end panel, (not really needed, I can still contact it by WIFI if necessary).
    I've also found that on the Y axis the micro switch tries to click after! it hits the end of it's travel - bad for belts etc. (still very happy with the design though - just the sloppy building practices they use don't help - nothing that can't be fixed!

    Careful about the micro switch settings, also getting the basic Cura settings all correct for your particular machine.
    I do hope you will pass on your findings with the new consumables etc.

    At the moment I am finding a little bit more time to look in here again - this was the thread which brought me here in the first place.

    I've been using Slic3r because it came with my Prusa printer. So far it's been fine. There is a learning curve with 3D printing. It takes a few mistakes to get the print orientation and supports right. It is like watching grass grow. My solution has been to watch the first few layers to be sure everything looks good, then do something else. However, I have come back after an over night print to find a huge glob of plastic on the print head. These days I use a silicone cover to make it easy to remove the mess. My favorite 3D print guru is Makers Muse. He's Australian, but don't hold that against him. There are lots of other good videos as well.

    Lohring - I have more or less found everything that you have found to be true, yes I did have a few orientation mistakes with Cura too but went back to the start and worked out the settings and it's all fine now, but I'm still right down at the lower end of the scale as far as knowledge is concerned!

    Unfortunately things like silicon sprays make me feel ill (or do you mean that you use some sort of silicone fabric?).
    The hairspray I'm using doesn't thrill me too much either, (and don't take that the wrong way, I'm actually quite bald), but that and masking tape seem to work well together on my printer - I don't see any need as yet to use a glass bed (just extra weight and more stress on the machinery!)........ that's how I see it anyway!

    Yes, Maker's Muse is good too, my main source of info still comes from Lars, but there are so many of those type of videos, the majority of them are good and do help a lot with the learning process.

    Bottom line is though, we all still have to learn by applying ourselves and actually doing it and it'll be a slow process for me I'm sure!
