    new to 3d and if i had hair i would have pulled it out by now

    hi from bonnie scotland
    well at the age of 57 i need something to do and learn, i have ordered a 3d printer from the bay and now it`s time to find the software.

    what i want to do is copy items and i thought 123d catch was what i needed and then i found out it no longer exists, i would want to put an item down then take the 30 or 40 pics of it then load it into the software and reduce or enlarge it before printing it. i am not looking at designing from scratch at this moment but simply taking the pics then altering the size before printing.

    now the question is do you guys know of an easy free bit of software which will allow be to do this?

    i would love to know your thoughts on this as there must be easy to use software out there that covers something as straight forward as a simple copy process, once i get used to that side of it i will no doubt look further into the fun of 3d printing but that is something for the future.

    thanks guys.

    the biggest issue I've had with trying to make a 3d model from pictures (never succeeded) is that you have to move the camera round the object.
    That said - here's the best way to do that I know of : https://www.thingiverse.com/thing:1762299

    What printer did you buy ?

    If making accurate, high-definition and printable 3D models from real objects was as easy and cheap as you wish it was, then nobody would spend thousands of dollars and hours on 3D scanners and their associated software. 123D Catch was an attempt at short-cutting the process, but it never really worked very well. I haven't tried the Thingiverse thing aardvark points out, but from the mesh in the picture it doesn't look like it manages to capture detail on small objects with any kind of fidelity. If you're using the meshes in something like an animation project, then a low-res mesh like this can be all you'd need, since the photo-texture mapped on top of it conveys an impression of detail as it moves. But for 3D printing, the detail needs to all be there in the mesh.

    hi awerby
    i never thought it would be easy and from what i have read im even more confused now, thats why i am on the forum asking advise and hoping that a few who understand these things pass a little of their knowledge over to us beginners.
    as i said in my op its only ornaments, actually i am going to copy 5 grand daughters garden ornaments before they are handed back, its a great way to get the printer running and me learning so no animation just solid items then at a later date when i am comfortable ith it i can copy parts of my lee enfield and make up the other three enfields i have which are missing parts, method in my madnes and i will save a fortune if i can print my own parts.

    thanks

    looks like a prusa I3 type. decent build volume too - which is good :-)
    137.88 !
    Even for a kit, with heated bed, decent psu - that's amazingly cheap.
    You realise it's a kit right ?
    ie: you'll have to build it from scratch.
    Interested to see how it goes - that's stupidly cheap.
    None of the pictures show filament being fed. Can't work out if it's direct drive or bowden.
    Bloody hell you can get them with delivery from uk warehouse for 129.99.
    wonder if they work :-)

    As far as the guns go - you'd be better off with digital calipers and designing from scratch.

    Have a look at Openscad. http://www.openscad.org/

    I find it much much easier to use than most cad packages as I don't have to draw anything :-) Just tell it what I want and where I want it and it does the rest.

    well its turned up and yes it is a kit which to be honest i never realized but i suppose i will learn a little more about 3d printers! so from what you have said about the printer it seems to be a decent spec for the price paid, lets hope it measures up then lol.

    yes i have digital calipers to measure the parts needed for the lee enfields, they are only wall guns so no one would know the difference anyway.
    i have found software which allows me to photograph the items from all angles so i will get on with that before using the final file into software for printing.

    what software are you going to use for the scans ?

    And yes you will learn an awful lot while building the printer :-)

    It's not quite as straightforward as: take 100's of perfectly exposed photos all under identical lighting conditions, let program make 3d model. Realise what you have is a distorted pointcloud and you need to convert that into a mesh and then try and repair the mesh and then convert it into an stl file. Then you'll need to edit and adjust it so that it almost-but-not-quite resembles the thing you took the pictures of in the first place. Then repair that so that it prints.

    That's been my experience anyway :-)

    Oh, and under no circumstances be tempted to buy a ciclops 3d scanner for $99 - you can have mine for 40+p&p, they simply just don't work.
    Somehow they've made a video that lets you think they do work - do not be fooled. They are completely and totally useless.
    Mine is still for sale though ;-)
