Creating Molds

I need to create a mold and wonder if the 3d printer can do this.

Thanks

Hi @salayna,

A couple of weeks ago I came across this video.

I am sure it will be interesting for jou

Yes, it can be done easily with 3D printer. Just print out with PLA (PVA can be burn out)or PVA(PVA can be dissoluted) , And make a mold out of the printed object, and get rid of the printed materials, and you got the Mold leave behind.

Is there anyone in Ottawa that I can discuss this with? Thanks

salayna · 2015-09-10T12:43:24.000Z

Can you do this?

Yes, a 3D printer can be used to create molds. It is a very common practice to do this. Of course, the complexity and surface quality of the mold and the success of creating the desired mold with a 3D printer is dependent on the 3D printing technology used. Extrusion type printers (FDM, FFF) will generally make rough surfaced molds of limited complexity. Other technologies, such as those used in the ProJet 3510 series, are capable of producing smooth surfaced, highly complex molds.

I am in Ottawa at Envirolaser.

Hi Steve, thanks for the info. Mine would need to be smooth aside from lettering on the top. I want a oval 5 ounce mold with the word faith on top in cursive writing. Sounds simple right?

salayna · 2015-09-10T14:38:38.000Z

Can I email you a picture of what I want?

Hey @Randy_1, you should get your printer back online, so @salayna can email you: https://www.3dhubs.com/ottawa/hubs/envirolaser

3DSteve · 2015-09-10T15:24:43.000Z

Before we can relist our ProJet HD 3000, 3dhubs will have to modify their estimation software as it doesn’t accurately reflect the costs involved with MJM printing.

3DSteve · 2015-09-10T15:28:01.000Z

Sure. Just call me first.

salayna · 2015-09-10T20:57:53.000Z

I sent it to you. Hope you received it.

salayna · 2015-09-10T21:08:56.000Z

I have seen this. My hope is that I can do this with a 3d mold that can be created with the printer.

Clean3D · 2015-09-10T21:30:24.000Z

Depending on the complexity of the mold, I may be able to help you with my Ultimaker 2.

salayna · 2015-09-10T23:49:41.000Z

Saw it before and love it.

salayna · 2015-09-10T23:52:41.000Z

If you email me I can send you what I am trying to do. salayna2006@gmail.com

We may be able to do this depend on what is your end result material of the mold. We currently have PLA materials,that can be easily burn out. Or we can get PVA material in that will dissolved in water. Our MasterRap 3D printer will able to create super fine and smooth surface since our printer have exceptional capability to print layer thickness could possible down to 10 micron thickness level. And We are located in West side of Ottawa.

You can check out our hub profile where a sample of 25micron layer thickness was printed with ultra resolution. And if your shape is simple Oval, with cursive letter on it, it should be simple, no need to using burn or dissolved method. As we also have experience create rubber mold from plastic LEGO piece object similar to the example video that you post. We can take a more detail look into your project if you email your object to:

Hi all,

We have some experience in doing this with various materials (rubber and latex).

You want to make an AIR-TIGHT mould, so use a thick wall!

Otherwise the material will go places you don’t want.

And making a low pressure chamber with a plastic box and a vacuumcleaner can help bigtime!

If you have specific questions - don’t hesitate to ask
