Default 3d printing

Hi all,

I have not seen a great deal of mentioning 3d printers on the forum, but I recently purchased one mainly to use for the layout. It was a DIY kit from China, but is very good. Has anyone ventured into this, and if so, apart from thingyverse is there any sites they know of to download models, either pay to download and print yourself or free sites. Many thanks.

Please can you tell us more about this DIY kit from China?

The topic of 3D printing has been discussed on this forum, but not recently. The freeware program you will need to learn if you intend to create your own models is called "Blender", but expect a steep learning curve! You will have to create your 3D model and export it the file format your 3D printer uses.

Blender is very hard to use.

Metasquoia4 is not free, but it is easier to use than Blender.

Mesh lab will convert a point cloud into a vector polygon. This would enable you to sculpt an object, such as an engine driver in clay, photograph it, and scan it into the computer.

Papakura will enable you to create an object in card to assess the feasibility of a 3D model without wasting time and materials on "experiments".

Papakura will enable those without 3D printers to create objects from 3D software in card. Once you are familiar with 3D software, it will be easier to make the transition to 3D printing.

VisualSFM is the program which will create a point cloud from a series of photographs. You will need a high spec computer for this application.

Could you let us have a link to details of the printer you purchased it sounds interesting. Thanks

Always avoid DIY kits that's my advice.... I had one, and didn't have any instructions, program to run it, nothing, been sitting my garage un used.
I have been watching the 3D printer market for some time, and done a lot of it including what's written on my topic.

Can get some good hi resolution resin printers from 400-550, which are good value for what they can do.
The filament printers are hit and miss, some are not bad, but need to pay mega money to get a decent print and reliably print.

The thing that strikes me is the extremely long time it takes to create an object, and then the amount of work you've got to do finish the object.

I think 3D printing is good for solid objects such as a pillar box, but not so good for things such as signal boxes which are more easily made from card,

Thanks for the replies, the kit that I bought is from here:

https://www.banggood.com/Tevo-Tarant..._warehouse=USA

I was though more after sites that had already models designed that can be downloaded.
