prototyping: sla or 3d printing?

[CADEnrico]

Hi.

I made 2 models (base + cover) and would like to make a prototype.

the external dimensions of each model are: 50 x 30 x 10 mm^3

in the past I made prototypes in protogen or xt 18420 material and I found myself very well, only they are a little expensive.

I read that it is possible to make prototypes by 3d printing and I wanted to ask the forum:

1. What features does the prototype have in 3d printing?

2. Does the 3d printing cost more?

Hello, and thank you in advance

hi enrico, I think 3d printing has a better definition while the sla is roughly 0.025mm for 3d, 0.1mm for sla.
greetings and

 

[IPdesign]

can you better define the type of 3d printing?

In fact we have understood,
but for 3d printing I have ideas a generic clutch
you mean a 3d printer type fdm
or a sls, or still with photosensitive resins?

Hi.


As I told you, I made prototyps in sla with protogen or xt 18420 resin and I found myself very well. In particular, the surface finish is very smooth and the dimensional tolerances are 0.1 mm which is excellent.
The only problem is the cost.

I'd like to know if someone made prototypes in 3d fdm printing and how they found themselves in terms of cost and accuracy.

hello and thanks for the answers,

Consider that I speak to you as the owner of a 3d fdm printing service,
So I'm interested in it and I could give you info that they bring water to my mill:biggrin:

As far as precision is concerned, I don't think you'll find yourself surprised, on x/y axes, accuracy is well below 0.10 you've encountered.
for the z axis instead we have the mechanical limit of the fdm technology that consists in the layering layer that could be of
0.25/0.33 when using new machinery (sizes 768 or 1200 )
0.25/0.17 if new generation printers are used (elite size )
up to a 0.12 if you use other end machines for high productions (stratasys )
costs : it is the black beast of those who deal with it as in my case provide a service to third parties and each company generically priced that believes more congruous for its market according to the service rendered. (speed, quantity etc.
)
It should be said that costs generally vary and for some technologies of a lot if the number of pieces is higher than the single.
in fact the technologies that exploit the laser can optimize and of a lot the yield of the production process filling the area of work as the dead time of the machine is given by the preparation machine and then from the change of layer (the laser is very fast )
different speech in the fdm where a thin thread of abs is melted and deposited.
I always like to simplify the description as if it were a milling machine that works on the contrary, one removes material and the other adds it.
in the latter case it is well understood that you have no interesting advantages in performing multiple pieces at the same time. and consequently this falls on costs.

In my humble opinion, the costs are equal on small batches,
the choice therefore must be oriented to the needs of the customer.
depends on the customer in fact segliene a product compared to another according to the use that must be made, evaluating and tapping with hand the various technologies.

Obviously considering different suppliers you can always meet with companies that decide to adopt incorrect commercial policies and of doubt value, I refer to how many work undercost or with poor raw material, and this applies to all categories of products.
in the end the result is to provide a low-cost product but with absolutely diffuse features from how much a serious company could provide with the only result of putting in bad light a category that strives to bring to its customers always the best of technology and innovation.
but here in all sectors I exist the "furbi"

non e' un problema.

valuable and detailed information!

Let's see if I understand correctly:

Is 3d fdm more convenient in case of 1 prototype at a time?


I have 2 models, between today and tomorrow I go to your site and send them to you for a quotation.

thanks for your time,

much depends as I told you from company and company.
In general I am more competitive on 1 or 2 pieces per type, while I have to leave the step on 5 or more pieces.

for the quote you can also send the models to studio@ipdesign.it soon and I hope to bring to try also the aps

I would also be interested in printing a prototype... I will contact you shortly for a quote! Thank you.

I look forward to your request
do not forget to mention cad 3d in the same :biggrin:

 

[Protigy]

try photosensitive resins in addition to fdm could be useful for comparison... I'm gonna put some water in my mill. :biggrin:

Hello.
I read your discussion about the occasion to ask you, I have to create prototype the problem is that they are two pieces made up of different materials that you have to frame and hold. one must be made of hard plastic other instead must be silicone rubber.. Now I need the prototypes of both pieces but one of the two must be of the elastic consistency of the silicone so as to have correct ink besides evaluating the elasticity of the same piece as I planned or not to have a rigid shape drowned inside the same in case of unstable... I don't know if I explain, you have any idea how I can get this prototype... (picture seat 3d)

I think yours can be a job to do with a connex

 

[modelleria trend]

I have just purchased a 3d printer of the latest generation, an important investment for our company that realizes and develops models for footwear funds , I would also like to do service , i.e. print out third-party projects , make available my printer for rapid prototyping after compensation .
Is there a website that promotes this service? thanks nicholas silenzi 3282710641 modelleriatrend@gmail.com

 

[paolofo]

as already specified by ipdesign, 3d printer is a very generic term, the ideal is to indicate the technology used, stereolitography, sintering, fdm etc.
Moreover, remember that every technology entails pros and cons: surface quality, mechanical resistance, cost.
the best ratio of these parameters must be based on the characteristics required for the model.

Good protigy, let's hear it! ! !

 

[fast3d]

seems to be the bicomponent you're looking for. If it were so ip design is right, connex is the only solution. ask for a quote info@fast3dsrl.it specifying well the shore to and the desired functionality.
