cad for design orthopaedic envelopes/corses?

[GiulioB]

Hello, everyone. I would like to build a line of orthopedic busts to help adults with curved foams to support a static posture for a long time. the technique I have in mind is to traction the patient, "scannerize it" with a 3d scanner, import his 3d model into a cad program, and then through the program "build it around" the bust. the envelope must dress its torso, then be modified in the program itself to add the due thrusts. shape, thickness, hook: I have to manage everything. the final product would be printed on a wide format 3d printer.

But I should learn a software cad from scratch, and I wonder: what? Would you have a suggestion? For example, would it be possible with solidworks? (right I see that it is the most popular).

Thank you, if I can add something to clarify I will gladly do.

to achieve this type of work, a cad can accurately read the result of 3d scanning and manipulate it to achieve a manageable model on which to build the corpetto. Once you have ascertained that the chosen software can interface with the result of the scanner, good or bad all modeling cads of the same price band of solidworks have a surface modeling module (for some, perhaps, it is an additional package) that can be used for this purpose with the creation of relatively simple forms and the possibility of exporting a stl file. based on the technique and the printing material that you use, the model may require any adjustments to make it feasible and support the loads without breaking, but, as written, are functions that generally the cads of this band have.
note on the margin of the project: the idea, if not innovative, could be valid but, without the support of an expert who knows what and where to correct, you risk to realize an object that, instead of bringing benefits, goes to impose a wrong posture to the patient.

since you will use prelatively targeted surfaces on a cad that manages them easily.
You don't need it to be parametric, since every project will run itself.
over 25 years ago I used thinkdesign to make plastic molds and, compared to other cads, I found it very intuitive and easy to use. was an Italian product made of bologna and did not cost a bang (then ) .try to inform you
Hi.

I would say that powershape could do for you, certainly you do not learn to do something like this from today to tomorrow

having to process scans I would direct myself on a special software, like geomagic. you can choose solidworks+geomagic for solidworks, or geomagic design x. if you want to make a more mechanical modeling.

or if you feel you have to make a freer modeling, you may also consider freeform geomagic.

I would be rather curious to know which scanning technology you rated. digitizing a human bust, I don't think it's trivial operation.

Thank you. I'm trying to clarify my ideas, I'm evaluating what you said.

I answer:

I know what to do.

I presume free, but I am not sure, because I have in mind only the final product, I never even opened a cad program anyway there would be, at least at the beginning, "mechanical" components beyond simple joints between plastic parts.

if the modeling you have in mind is: "I take a sheet of paper, wrap it around the patient, cut off the excess part, I make some hole in the middle, give it a thickness, fitting the edges, to the limit I build some reinforcement", then a cad is fine. even a parametric like solidworks can work. better if you have integrated effective reverse engineering functions.
If you want to "take a mass of clay and pushing and pulling the form I need", then approach freeform.

I was hoping you'd surprise me with something specific. I'm afraid the patient has some difficulty staying still all the time of the acquisition.
edit: I saw a video... I'm almost surprised!

I start from the patient's torso model. Once I imported the model on the software cad, first of all, I need to "dress it" with a plastic layer of some millimeter, whose thickness must vary depending on the area (also very substantially). at this point I work "hand" the surface so created, narrowing it and widening it, pulling it, pushing it, etc. to give it a new form. then I add connections and hooks, and I make aesthetic finishings if necessary.
I'll have to do tens or hundreds of prototypes, so wrong is not a problem. I have at least 6 months time to make a full-immersion in one or more software cad.
I'm looking at freeform now, it seems to me to do the case!

edit: I'm also looking at fusion 360 with powershape.

 

[GiulioB]

at the end freeform seems to me the most suitable. I would say the problem is solved for now.

I'm glad you could have been helpful. Keep us updated!

I had already "studied" blender, that is, trying to figure out if he could at least do what I have to do. what I arrived at is that, with a blender I can start from scratch to create a form, but instead: import a pattern of chest and head and "dress it" with a layer of material of a certain thickness?

I found an add-on doing it now (it's called wasp):

 

[flaviobrio88]

depends on the time you have, and especially on the business if I were you I would go on a pure modeling software on surfaces.
Maybe it has n good reverse engineering and a deformation tool that can meet your needs:
Consider that a tool that allows you to deform surfaces saves you many times modeling from scratch.


blender is a good compromise if you don't have too much tolerance needs.
