I am reviewing the options of going to a 3D printer for a few parts I now have blow molded and CNC'd. Anybody have any experience with this?

No experience in 3D printing, but from what I have seen it appears slow for a production process, more suitable for prototype work. That being said I have no idea of the quantities you require so it may be a viable option for you

 

You really can't beat injection and blow molding for speed and quality if you already own the molds.

Mainly I was looking at a CNC'd part out of UHMW I have made and if the ABS would be up to the task. Time isn't an issue if I can bring the cost ($12.50) for a blow mold part down to below $3.00 to print.

 

Still looking into this. Also looking to buy files to print skulls. Cool stuff.

Can you print yourself a print machine?

We have an objet we use for prototyping here in San Rafael. It is pretty slow (print overnight) and the material is very expensive and they are the only supplier.

A 6" x 6" part may run close to $35 in material.

OUCH!

 

Which unit do you have, MakerBot?

 

Is that a solid part?

I wanted to build one last year, just use it for thermoforming molds. Forget $3/part. More like $30. It's not regular plastic that is used for blow-molding, injection-molding and thermoforming, it requires some pretty expensive resins that cure right after they exit the nozzle.

I'm seeing PLA (organic) and ABS as the two most used filaments. How can ABS be expensive?

 

I've also seen that polycarbonate can be and is used.

There is plastic, and then there is plastic that needs to have the precisely controlled viscosity to flow through an electroviscotic nozzle in picoliter volumes and cure on contact while having the requisite stability to store for extended periods in the printer and then flow on demand through capillaries.

 

Might be why it's expensive.
