    3d printers.

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all.

    I am looking to buy hubby a 3d printer for Christmas this year but know next to nothing about them.
    Like a lot of things, the more I read, the more I get confused.

    I have seen a couple of people mention them here so thought I would turn to you guys for some advice on which one would make a good purchase.

    Please try and keep it basic

    Ok keeping in mind Im not affiliated with anyone, sell them, know everything, just an enthusiast, much like my coffee.
    Now 3d printers or Rapid Protoyping Machines, are printers that use filament (picture a roll of wire, but its 1.75 or 3mm thick plastic) in materials such as ABS plastic (can give off odours) PLA and PLA+ I used to print with ABS but mainly use PLA+ and it works fine.
    Each material has its own characteristics, ABS, very strong but melts at much higher temperatures and is better suited to machines that have an enclosed box to print from such as a 3d Print Systems UP+ or UPMini, both of which I own and can speak from experience. They come with proprietary software that take the STL file, which is the format 3d printers use to print an object, polug it in load and press print.
    Think of an inkjet printer, it prints along an x and y axis to print something, 3d printers work the same except add in an Y axis or vertically,
    You use "slicing software" that take a 3d model and "slices it" picture an apple, and sliced horizontally in .1 .3 increments vertically. So, you have an x y plane ie looking from above the model which tells the printhead or extruder where to go then add in the Y axis gantry or vertical plane and as the machine squirts melted plastic on one sliced level, it increases height and prints another level, level upon level then creates your 3d printed object!
    Hope I explained that ok,
    Now 3d printing machines have severe brand loyalty worse than ford vs holden vs ecm vs la pav vs azkoyen, get the picture?
    No matter who you talk to their machine is likely to be the best. Don't be put off my non "brand names" like MakerBot etc, just because a machine is 2k in value doesn't mean its going to print better thana 200AUD machine, trust me I know from experience.
    Having some technical knowledge is advantageous, if not theres 4million facebook groups and youtube sites to choose from.
    If hubby knows one end of a screwdriver from the other, I do however recommend the ender 3, it comes in whats called a shortform kit, ie flatpacked. Took me 20mins to put it together, downloaded a file from Thingiverse.com (free site designers upload files for all to use under creative commons licence - ie you cant make money from most designs but free for personal use, but you can flick the designer a few bucks to say thanks - recommended)
    YOu download a file processor like Cura, load your file, like this morning I printed a portafilter holder and portafilter thingy for the sette 270 to stop grind spilling everywhere, pics to come! And 3.5hrs later model printed and being used.
    Now also keep in mind there can be some finishing to be done on the models, usually not much. Undercuts or where there is nothing the printer will add in whats called support material,
    Picture a portafilter on a bench, there is areas that do not touch the bench under the filter basket holder and handle, the slicing software will add in easily removed support pieces so the printer can "print in mid air" kinda thing, these are usually easily snapped off, depending in what resolution you print in, ie draft quality or final hi res you might need to sand paint etc.
    When I first started using these I was printed costume replicas and parts, think Ironman helmet things like that, theyd all need sanding, finishing painting etc, now unless your Legacy Effects (makers of Ironman suit) and have about 400k for their printer, a 200 one can get you there, just takes longer and more after work required.
    But for most gadgets kicknakcs and well, loads of coffee related items an under 500 printer will do just fine.
    I made some additions for my Mazzer mini grinder week or so ago and you can see the simple things that can be printed and used almost straight away.

    I hope this sorta helps you understand a little more about them.
    Please ask away your questions and Ill try to help best I can.
    robusto and OCD like this.

    Most helpful yes, thank you.

    I was looking at the Flashforge Dreamer but now I am not so sure.
    It looks like the one you have suggested would be just as good.
    So I am currently looking at the Ender 3 Pro or possibly the Ender 5.
    Is it worth paying for the glass bed for the Ender 3? As far as I can tell there is no glass bed option for the 5.
    Also is one brand of filament better than another or is it much of a muchness?

    Technical wise hubby is actually an Electronic Engineer so no issues there. I just can't ask him anything because our son and I are doing it on the sly.

    Thanks again.

    YES TO GLASS BED!!!! I bought a glass bed or borosilicate glass from that A to Z company (sorry non site sponsor) for like 25 I think,
    flash forge Ive heard good things about so no real issue there, but printers are sorta printers, enders do fine till you work out what you need and the build plate is a good size, I printed an ironman helmet on one

    I hope this doesn't confuse things, however some of the newer models do 20% carbon fibre / 80% nylon. I only mention it because if I was an engineer that would be my go-to technology.

    A 1Kg roll of the carbon fibre mix costs him about $75 (however 1Kg of that is as strong as about 10+Kgs of the others). My brother landed a 3D printer in West Oz for about $A2,500 however he also ordered the stainless nozzle to match. No idea of the brand.

    Thanks TampIt.

    We decided to start out basic, we went with an Ender 5.
    If he wants to upgrade then I will leave the research to him so he can decide what really suits his wants/needs.



    Thanks all for your imput and I'll let you know how he goes in due course.

    Thanks again.
