Bienvenue à OpenBuilds.

À noter que la grande majorité des conversations sont en anglais, mais il y a quelques francophones de cachés ici et la.

Bonne année 2015 !

 

cool idea

 

Not to go off on a tangent, how does one program an inclusion in a 3D printer ?

The bars would have to lay flat and not stick out more than a layer (that's thin as heck, no ?) so they won't get in way of printer's head. Or can one program the printer to go around obstacles ? If so, would one print a 'gutter' (probably half the depth of inclusion to drop or snap it in without messing up alignment) and then carefully print around and over it to eventually 'swallow' it whole ?

As it relates to CNC routing/milling - showing I'm still green, how would one also control the generated g-code to mill/route things in a specific order ? The latest release of SketchUcam mentions using layering and ordering them as needed to work areas with 'specific' tool.

I'll have to play with this ability and the generation of 3D g-code soon enough. Off to my build/resource, so I don't "pollute" this build with my learning. I guess one would have a program generate in segments and manually link them for finished g-code before sending to his/her machine to mill, router or 3D print accordingly ... Easier said then done (for me at this stage).

 

Is that just like an expression to refer to a bicycle or a motorcycle (using tangential wheels, blabla ...) or are you riding one of these on those sunny days :


As for the aluminum (or anything else) strengthened 3D printing, anything is possible. It's more a question of being worth the trouble ... errr ... effort, or, more important, the cost. It would be a good way to get rid of the scrap metal though : bury it in 3D printed parts.

Maybe just use the carbon fibre laced filament from Proto-Pasta (see KickStarter here). Only 144$us for a 2 kg spool of 1.75 mm, plus shipping (about, what, 4x cost of regular filament?) with a dual extruder or filament swapping while printing, strategic use of the 'CF' filament should add strength where needed (?)

Proto-Pasta is also about to come out with a stainless steel laced filament ...

Some say 2015 will be the year for all that is 3D printing.

But are we now leaning to 3D printing specifics (or theories) rather than a CNC router/mill build ...

 

Have you seen the more recent filaments, some with likes of 20% carbon fiber ? Should help make the 3D printed parts much stronger/resistant. Although the cost might climb ...

 

I think someone had mentioned at one point, somewhere, maybe not here in OB forums, to make sure to have edges, including that of holes and any other openings, be made extra thick (more 'fill') while the rest can be 'lighter'. (How many commas can one have in one sentence ?!) Then again, I should take a peak at your design as you might already have done that given the 'pretty stiff' results.

Just a passing thought ...
