Thank you, Thank you, Thank you. I have always been interested in resin casting and after watching your video I am excited about the process of making car bodies and parts. I am going to watch the rest of your videos. Also, I have never used resin before so I really appreciate you sharing the process of using it as this is how I learn more about it. Thanks. Jeff

[@BaronMcCausland]

How do you know how much resin to pour to get a complete fill? Since you have no venting to allow excess air and resin to escape, what becomes of the extra resin in the event that you over-fill the cavity?

[@turboflush]

So when scraping the clay.. is it level with outside of model? Leaving the thickness of model into the clay?

[@keithsmodelsandrcs6593]

Super talented id love the know how cause he makes it look so easy trust me its not as easy as u wish. Hes a natural great kooking resin cast too well done

[@m-rezaaghdamibaher7876]

[@smoothon]

Thank you for watching!

[@luistrujillo6320]

Great video!!!, I would like to know, how you decide between pour the resin into the bottom halft of the mold or through a channel just into the bottom area too of the mold? wich method is better and why?

[@aryehtench331]

Excellent video thank you so much!

[@smoothon]

Thank you for watching!

[@BaronMcCausland]

How are you ensuring a complete fill, and therefore void-free castings, without venting, gating, and spruing your tool?

[@smoothon]

The squish mold technique helps to eliminate these voids but there is a risk. Also, testing different amounts used to fill the mold can help determine the optimum fill level to allow air to be squished out.

[@AlenHR]

Man, I got hooked up on casting.

[@akluvr47]

how do you determine the amount of resin needed the calculator on the site doesn't explain how to estimate like a car body it only has solid object measurements?

[@alexv4700]

One year later ,watching this video and I’m wondering the same thing. But science to the rescue : use a graded water recipient, fill it to an specific level( like 1000 dm3), submerge the object, measure the difference, that’s your volume. The density of the resin should be easily available and from those two you’ll get the amount of resin needed( the mass).

[@NeilWB]

An excellent tutorial - but what to do if you do not have degassing facilities - i.e a vacuum chamber?

[@ryanbarker5217]

if you're mechanically inclined, there are tons of DYI videos. i'll buy mine, though, they're not horribly expensive. but, if you don't have one, you'll have to risk bubbles. based on what i've seen, you can reduce bubbles by pouring high, then tapping the sides of the mould.

[@mainstay.]

How do you know how much of the Task to use, so as not to get a lot of 'squeeze out' and thus preventing a 'thick' cast?

[@smoothon]

this depends on your particular application. This is a good question for our tech support team, can you send them a ticket here? www.smooth-on.com/support/ticket/add/agree/ Thanks for watching!

[@mainstay.]

@@smoothon Well I was obviously asking in regard to this application - the one you used in the video. Usually I pour water into the mold and measure the volume, but with a mold as this, I wondered how you did it. I guess you just discovered the volume of the car itself.

[@liveuntetheredmusepodcast4832]

Excellent video!

[@smoothon]

Thank you for watching!

[@pprotory]

Would like to see a video like this but using vent sprues and either injection or pour method.

[@Brakzillaa]

Pretty much the same thing. Just add a pour spout on the underside roof of the model upwards and a few vent sprouts on the sharp points of the bottom of the model. lol

[@طولون-ظ5ظ]

I am from Egypt, my friend, and I want a way to import the casting product that you mentioned, which is urethane. Thank you very much for this beautiful information that we can benefit from.

[@smoothon]

Thank you for watching! Here is a link to our distributors in the middle east. www.smooth-on.com/distributor-regions/middle-east-india/

[@Mrddrichards]

How about 3D Scanning the object and then using a Resin 3D Printer to print the mold halves? There are 3D Printer Resins intended for casting.

[@smoothon]

That would be one way to do that however silicone allows us the advantage of having a flexible mold that does not require mold release when pouring resin into the mold to create the replica.

[@fiskusmati]

How you dealing with thin screw holes seen in 6:58? You block them, and then later drill out in every casting?

[@RodderFiles]

How many clean bodys can you get from that mold ?

[@DAVEEYEINTHESKY]

thats was awesome, it would be great if you could show a video of making a cast with iron metal powder and resin to make a rustable model that can be put in a garden to get rusty with natural weather as im casting a life size robot head from a popular film and have already made the silicone mould and brought the iron powder ready to cast with my polyurethane resin. thanks

[@scottrados9413]

Ok Milo- excellent video, but the one question that I have which wasn’t discussed, was how to figure out how much resin for pouring the car itself?

[@makers_lab]

You can use water displacement. Fill a container on a scale with water sufficiently to be able to submerge the object, zero the scale, submerge the object without pressing on the sides or bottom of the container and the weight increase in grams will be the volume in millilitres plus that of anything suspending the object that was below the water surface.

[@georgew.penguin1154]

After making this part would all the other missing bits need to be cast from the same material? In other words could I just glue other parts made of different materials to this, like styrene?

Thank you.

[@golden_boi77]

transparent resins require vacuum. you require a large chamber to fit you mold into.

[@fuentesdrevon]

Hey I wan to do a casting or a scale car model like the one that you used on this video. But i have never ever done any molding or casting work. Can I use the same silicone that you used on this video without the vacuum spet? I dont have anything to do this step vacum out the air bubbles. The casting is for a proyect of a small car robot. And i expect a lot of tear and breaks if the casting is rigit plastic, on the process of testing the robot. So It would becaome handdy to have a few scale car models that are a little flexible and strong like the casting you did on the video.

Also no one mentions pressurizing of the resin to get it nice. Good products, just a few rants.

Hi, looking at your video and getting inspired, and I'm curious about setting up a vacuum degassing system, I'm wondering if there are any special requirements or considerations to think of when looking to purchase a vacuum pump for this application? If your vacuum chamber is for instance about 10 liters/ 2,6 gallons? Does the power/ liters/ pr minute of the vacuum pump matter? Or will a small pump jus take longer to produce vacuum in the chamber ? Thanks..

[@smoothon]

You will want an 8 CFM vacuum pump in order to pull the 29 inches of mercury required.
