Some advice for you mate, I've been a jeweller for 40 years, so I know a thing or two. When cleaning up the ring, leave the main sprew on, it means you can hold it very easily while fettling the piece, you can even wait untill after the main polish to remove it. Just a tip. Hope you take no offence at the sugestion, and it helps.

Good video. I took an adult education class on Jewelry Making years ago taught by a very experienced person. I remember two good tips: 1) Coat the wax masters with dilute dishwashing spot remover before putting into the investment. It's just a wetting agent and will allow a more intimate contact between the investment and the wax. 2) Eucalypts oil dissolves wax readily and can be used to "polish" the wax master before casting. I think it would also work on the 3D printed master.

You can actually do the conversion from wax to silver using water displacement. If you have a measured amount of water in a graduated cylinder, you can drop your piece in and measure the difference. Take the difference and using the density of water, you can then write that down and do the conversion from silver density to water density. Google will tell you that in a split second, so it's not too hard. Add a bit extra silver to account for losses and sprewing!

Wax/castable resin is made to be equalvalent to water so to termin metal weight just multiple wax weight by the specific gravity of the metal then add between 5-15g for the sprue

I actually made a plaster mold of my old flask plugs and use it as a mold with PMC rubber from Smoth-on I use the PMC 121 I use the PMC 121 for both my wax molds and for making new plugs if I need to

In high school I did a lost wax casting in my material science class with a centrifuge to force the metal in to the cast. I had to carve my ring out of a blank and it was a learning experience

What class was it

for your purposes, set your scale to DWT. weigh (all spruing included) your piece and multiply by 10.5 for sterling silver, 8.5 for bronze (good for master molds) and 14.5 for 14k gold. also, you can eliminate the pitting in the cast by setting your casting temp higher, i would say go up from 950 to 1100

Great work with only a week learning the lost wax process.. If you're melting gold make sure you have a reservoir mid way down your sprues as that will trap any porosity if the button doesn't catch it all, Have a little look into sprue designs.. some people recommend not having a sprue hit directly at a flat spot on your piece, If angled slightly it helps for a smoother transition. Just see what works best for you, Great work fun video to watch 👍

Great video. I've been getting into lost wax casting for the past year and have been dealing with a lot of trial and error. I've had a nightmare of a time getting consistent results from using castable resin. I know some advice given to me was flipping the flask at something to allow more ventilation and also having the final burn out stage at a slightly higher temp. It sucks that the castable resin is so expensive. Have you been experiencing determination or contamination from using the graphite crucible. When I poor out the excess amount of molten metal into a ingot I see black stuff/impure metal. Also....would it be possible to blow out the residue from the flask with out damaging the mold? I assume the left over resin would come out but I can imagine the sudden temperature change could mayne damage the investment? Also it would cause some flames i presume.

I didn't realize there is so much work in casting. Great video.

I have seen that and it looks like it would be helpful

hi thanks for the video, its nice to see someone experimenting with CAD and casting. I have two tips - just use a sheet of paper wrapped firmly round the flask and taped rather than using expensive and messy tape, it does the job with no fuss and is much less messy. As for your maths - the specific gravity weight of silver is 10.4 so you will need 10.4 grams of silver for every one gram of wax or 10.4 ounces of silver for every one ounce of wax or resin. You also need to add an extra ten grams (or equivalent) for the button and tree. So for two wax or printed rings weighing a gram each you will need 20.8 grams of silver plus 10g for the button a total of 30.8grams. Weighing your base before spruing up and after will give you the most accurate weight. hope these two tips help!

alternative for the wax, you can use wax straws as well, as long as it all burns out of the plaster its all good

Wow man that's some serious machinery, I really like that you experimented before going for the 3D printing, great work! 👍👍👍👍👍

Thank you so much for this video, its really helped me understand how this machine is used and what its for, My daughter is doing a degree in design and jewellery and will finish as a gold and silversmith with design knowledge, she will then need to go and do a apprenticeship for 5 years or so to perfect her skills , one of the things i want for her to have is a proper studio at home where she can feel free to design, explore and make pieces how she wants to. She has been using illustrator intensively in the design process and is very good at it and its great to see the use of the resin printer as thats what they are doing at the moment, the beauty of this of course is that you can reproduce the item time and time again however you do lose the "on off" ability skill that you get from hand making the piece and the uniqueness of it that you get by using wax yourself. It is a pity that you didn't include in the shoot the actual pour of molten metal into the flask and show it being put under vacuum. Thats what I understand the machine does so negates the use of a centrifuge completely by using a vacuum pump to suck the metal into every part of the mould. I use 3d printers quite a lot but using plastic not the new resin ones so I am not sure exactly as to the quality of the finished piece, is it better than a normal 3d printer using abs or pla? On PlA prints I sometimes find I use a spray automotive filler to get rid of any imperfections before I spray them but you were saying this is down to the burnout in the kiln not being perfect . Well basically this is a piece of kit I need to add to the list to complete the studio for Georgie rather than a centrifuge so its time to spend some money, over here they cost around the 600 euros mark in europe. Every one of these machines seems to be exactly the same just with a different badge on it, They appear to be all made in china which is fine by me if they are not made anywhere else. Again thanks a lot for the video and good luck.

Have you tried printing your sprue ups in resin instead of wax? I find that it tends to work quite well, improves flow.

realy informative video.the sprue burnt out perfect because it was wax..not so the printed medium.so for myself its wax every time.

Forewarning, I have not yet finished the video, but I just wanted to give you a heads up! If you connect your piece to another "tree limb" instead of directly off the main sprew, then it will make cleanup much easier for you afterwards. It will mean that it requires *slightly* more silver to cast, but it can obviously just be repurposed and re-cast as scrap. Edit: Never mind!

Hey hey im not sure if you already knew the tip im gonna give you but if you put pure lemon juice in a heat safe bowl like a chocolate fondue set with a candle underneath you can get the soot and other things of the silver:). There is a specialised acid goldsmiths use but personaly i liked the lemon juice trick better because i had my workshop in my bedroom:p.

The more you mix the plaster the faster it sets, the mixing breaks up the starter crystals into more starter crystals. I would place the plaster in the vacuum before adding it to the mold. Thats how we dental techs do it.

Ive been doing casting for about 5 years. The purpose of the investment and correctly mixing it is to minimize the air bubbles in your casting. I would suggest stop using the mixer for the investment thats why you invest it twice in the vacuum once in the bowl and then in the flask. But thats just my opinion lol

I've done last week's casting. For better results let the plast sit for 24 hours Whole temperature should be 1500ﾟ And you're one hour old should be 1000ﾟ And the plastic should be a mild cherry red. And your sprue technique is crude and awkward smooth and elegant Your other whole times look good

Throw some wet cardstock(like the back of school notebooks) between the hot flask and the red silicone/rubber seals on the casting chamber, just cut them to be the same sizes as the seals themselves. You should not have a problem with the rubber melting. They also sell high-temp seals if you want to go with a more professional set-up.

Couple of comments from an engineer, I've done regular casting, but not this. Other than expense, and depending on how you set up your print for infill, you can cut back on the amount of material used, but I would just print the whole tree.... That is, measure up and model the main sprue, and hang your castable pieces on it as a model. Bonus there is that your CAD program can tell you the volume, so you know exactly how much metal you need, less losses and having some extra for shrinkage. By using less than 100% fill, you obviously will use less material, but that also means there is less material to burn out in the oven as well. I too, agree you may be a bit low on your melt temperature to get good flow. A bit higher will help. A gentlemen said he puts his metal in the vacuum pot to degass it prior to pouring, you can do that, but I wouldn't just put it on the silicone mat as he did, just get a little bit more of that aluminium oxide mat material, 1/8 or 1/4 inch should be fine and put that under the crucible to keep it from burning. It will be plenty porous enough to get air past. I do not know however how much that will lower your melt temperature... boiling anything in a vacuum will lower it's temp, so you may even need to reheat it. A thermal gun to the side of the crucible should get you close however, and would be a good check to see if your table furnace temperature is accurately calibrated. I did enjoy and learn a lot from your video, thank you!

Hi! I just saw your video. I have just started too in wax casting for the last 3 months. One advice I can give you , that I found out the hard way, is better to design and print the sprue with the ring and also the tree. I design everything the tree, the ring with its sprue and print everything in the same batch and then put them together with a drop of resin and then cure it with UV light and Everything stays together. Other small thing is the time of burnout I have better results at least with 4 hours at 1,350 degrees. Hope this helps you, I need help learning to polish the pieces when the come out, I have mess a lot of pieces because of this, so after all the hours put on it to mess it up at the end is so frustrating. I can send you images of how I design the sprue and trees. Bye

Hi, can you advice me on a kiln question. My power supply in Singapore is 220v so the US made kiln would not work and using a transformer is out of the equation. Is there a another way to melt the wax away without this kiln?

If you ask me, the divots and scratches don't really matter on rougher pieces like the mandalorian ring, I think it rather adds to the piece overall. Also I highly recommend a silicone spatula instead of a wooden spoon for scraping out the bowl, it also cleans up both bowl and spatula much easier so you don't risk getting old pieces of plaster inside the mix, and also a lot quicker when washing out!

Try blowing bottled oxygen into the sprew button hole once the flask reaches the casting temp. Then place back in oven. The oxygen will remove any resin that may have attached to the walls of the investment.

How much did it end up shrinking by (the cast part from the size of the original print)?

Looking good.

Thanks 😁

Would it not be possible to 3D-print a negative of the object (basically a re-usable mould) in resin and cast wax forms in that to use for the metal casting process? I'd say that would speed up the build process right?

You might be able to do that but idk how well the wax would work in it as a mold. They have a clear silicone you can use for mold making. This is great if you want to make the same item over and over but if you are only going to make like 1-20 of them it might be better off just printing them.

Hello, Thank you for making this video. Did you get any porosity on the end product? You think this method can be used on yellow or white gold?

Porosity? also yeah you can do this with golds, copper, silver and brass if you wanted to.

Very interesting video! What sort of plaster do you use and where can I buy it?

Great video. I have a question. Do you know Geoff Thomas design? His rings have incredible detail. Can you get that level of detail with this vacuum process or would it require a pressurized vacuum system?

I just casted 15 small pendants in silver.. they are very detailed. What’s the best way to polish them to remove the “silver dullness look” ? I spoke with a jewler and he told me you can’t really polish them to much as the details will be removed.

Electric mixers may seem like they're saving you lots of time, but they are adding significant amounts of air bubbles to the plaster. Hand-mixing may be significantly more work, but will not give you so many air bubbles.

Yes but it’s limited working time plaster so you need to speed things up, and a vacuum chamber takes care of the added bubbles. So it’s the better way to do things.

@Shane Johns is correct. The best way to mix plaster materials is put your water in the bowl first and then sprinkle the plaster in a handful at a time , then leave it to soak for a few minutes, don’t agitate it or mix it yet. After a few minutes when it’s all soaked , you can mix it , you’ll find it’s super smooth and creamy and totally lump free. Minimal effort , no whisking. The more you mix and agitate the mixture , the quicker it will go off.

@@GomeowCreations I'll keep my eye out for them! We're getting into copper growing on resin prints as well. It opens up so many doors! All the best of luck! I'm currently buying some of your equipment too. It's nice to see them in action. You're gonna do some great work... I can tell. 😉

Great video. A bit late to it but here is a tip from a modeling point of view. Learn a bit of 3d modeling software like blender and create the tree in 3d and print it. You can get better channels and then you can attach that to the base. I would only do the channels and a min section of the tree due to print time and size and stick that to the wax.

Good points and yeah I have been casting a lot more in my new work shop and that would be helpful but I have also got a lot better at setting up items to cast 😁👍

I have found better luck with the porosity issue (the little holes in the cast) by using 50% new silver to 50% old, or pre casted silver.

if i use 2 inch by 2 inch flask to use one ring how longer will take to burn out in the kiln oven ? and how sooner can burn out time can be possible ?

Ah, good memories. I did a lot of lost wax casting in the 80's. There are so many better tools and technologies these days but the basic process is still the same. You can avoid most of the measuring with investment and water with a couple rules of thumb. To figure out how much investment you need, put your flask in the mixing bowl. Fill it with the investment powder, lift the flask up so it is clear of the investment, then put it back down in the bowl. Pressing it through the investment until it's sitting on the bowl itself. Fill the flask with investment powder again and you'll be pretty much spot on for how much you need. For water, we used a flexible metal spatula, like a heavy icing spatula. Start adding water and mix, keep adding water slowly until the investment slumps off the spatula when you tip it a bit. If it doesn't slump it's too dry, if it runs off before you tilt the spatula it's too thin. And when mixing the investment don't stir, but instead work the spatula from the center of the bowl to an edge. That both crushes any lumps of investment and also avoid introducing air into the investment. True, you can vacuum it out but the less you add the better :) With a little experience, and some trial and error, you'll be amazed how simple the investing process can be. Great video, full of good useful information.
