Im over here just wanting to cast car and gun parts lol. This stuff is incredible for lost PLA !!! Made a 68mm turbo housing using ESUN PLA on cad then used this stuff to make a negative mould. This is crazy ! Well worth the money !
How good is the detail and accuracy on the cast using lost PLA? That's my concern
I use this stuff to cast bronze at home and it's the cats azz! Thank you R&R for such a user friendly product!

Hi! Thank you so much for uploading this lovely video. It surely helped me in understanding the concepts and clearing up my doubts.
Keep up the good work! :)
You're very welcome! Glad it was helpful! Let us know if we can ever be of further assistance.
@@RansomRandolph mr robot may i ask you for a stainless steel cast i first apply the zircon sand and then the fused silica ( and do it dip it again in the slurry after i apply the zircon sand) ?
The sequence is always:
1) Dip in slurry
2) Drain slurry well
3) Apply stucco (sand)
4) Dry
5) Repeat for each shell coat (except final seal coat where no stucco sand is applied)
The stucco sequence is zircon (for the first 1 or 2 coats for steel) then fused silica.
@@RansomRandolph ty also whats the cheapest sand for stainless steel investment that i can buy from your website ?
Zircon is much more expensive than fused silica. I would first try using all fused silica stucco.
• Ranco Sil A for the first few coats.
• Ranco Sil B for the remaining shell coats.
If you do not get an acceptable surface finish on the casting, then you could replace the Ranco-Sil A with zircon sand and see if this helps the surface.
Thankyou mr robot
This might be a silly question but do you need to put this in a kiln afterward? Can you just bake it in an oven to get the wax out?
Sam, the mold will need to go into a kiln to fire it, which eliminates all of the organics and develops the strength for casting. If you have more questions, please feel free to email us at: technical@ransom-randolph.com. Thanks
Hi,
What SuspendaSlurry materials would be advised for casting brass components. Need to be supplied to Thailand. Thanks!
Zac, we will have our Sales Manager contact you to discuss.
I live in Australia and want to know if this is available there. Cant seem to find much in Australia. Cheers if you get the chance to reply
Hi William! Please contact our Global Sales Manager, Scott Todd, at: Scott.Todd@dentsply.com. Thank you!
Just another quick question. What price approx would it be for the slurry and sand? Cheers
Scott will be able to give you that information, William.
Should the slurry be stored in a low humidity environment?
Humidity control is not necessary for storage, but the humidity should be kept between 40-60% during shell building.
@@RansomRandolph so if the slurry dries out over time, one could simply add water and be able to use it again?
@@robinyilmaz1155 If the SuspendaSlurry has dried out, it is not salvageable. The material should be kept covered when not in use to prevent evaporation. When using the material, it is typical that some water will evaporate and must be replaced to maintain the viscosity.
@@RansomRandolph ah okay, but will it still dissolve/fall apart in water after drying, like investment plaster does?
@@robinyilmaz1155 No, this material will not dissolve or “quench” like an investment does in water after casting. This material will form a shell cavity that is broken away by a hammer or other mechanical means.
Any way I can buy some in Germany?
