I waited to watch these after they were all posted so I could go thru them at my own pace, I have done 22 in like 4 days now. To be honest after watching Lars Christensen for a year or more now, I didn't really think I would learn much just brush up from another perspective. I'll be darned, I have learned something new in every one so far. Great Job & Thank You for taking the time to do something like this !!!!!!!

[@ProductDesignOnline]

Hi, Frank. I'm happy to hear that you're learning lots! I will continue to make tutorials as long as there are people watching. I appreciate you taking the time to watch and comment. Cheers, Kevin :)

Wow what a great tutorial :) best one here on YT for creating a mold. 12min and I was done without any problems. you made it so easy for us. Thank you. Keep it that simple please :)

[@joppepeelen]

im like 2 hours new into fusion 360 and you helped out allot already. love the mould videos. THANKS M8 !!!!

Great! This is exactly what I want to learn. Thank you so much Kevin！Your expression is clear and precise.

[@RuderalisFPV]

nicely done, and very clear to understand. so many cad tutorials are narrated by voices very difficult to understand. your tips along the way were helpful and didnt get in the way of the lesson. thanks mang

[@onkarkitekt]

Trust this video to pop up after I've done it the longer way. You did it with a very simple method in comparison. The registration hole and combine features 🖖🏾🏆

[@qcnck2776]

Nice video and thanks for posting. May I suggest the registration marks not be symmetrical. That change would help reduce chances of accidentally putting the two haves together the wrong way.

[@ProductDesignOnline]

Great Tip!!! Cheers, Kevin :)

[@Hollywood4Fun]

Thanks! I just made my first mold following your vid. Will now subscribe. Wish I knew someone with an aluminum cnc milling machine to make my mold. I shall scan the interwebs.

[@SethJayson]

Thanks for the refresher. I have made several of these that I use for press molding custom carbon-fiber bike parts. It's very easy to do -- you don't even need parting fluid, you can just use kitchen cling wrap over the mold and lay up the wetted CF, press, clamp (I use more cling wrap, stretched, to provide the compression) and you get perfect parts.

[@ProductDesignOnline]

Great tips! Thx :)

[@specialagentdalecooper5367]

Have to give this video a thumbs down. Tried printing the doughnut without the molds but it tasted like plastic mostly, only ate one half before I threw it out in the bin.

[@ProductDesignOnline]

Hi, Special Agent Dale Cooper. It sounds like you forgot to add the frosting and sprinkles. Those should drown out the plastic taste enough to were you could finish it. Cheers, Kevin :)

[@curtbixel7806]

Can you include a link to the sprinkles?

[@makingcookingfixing]

Thank you very much for your video! This was the best I found in regards to making mold boxes in Fusion 360! I will save it and use as a reference for my future mold making adventures!

[@joncue0304]

First let me say I LOVE this video series. I'm just getting into 3d printing and am finding this invaluable. That being said, there are a couple things I'd like to suggest for the mold. I've been in injection molding for decades, so I may have a different perspective. 1) This is petty, but at least in my experience, they're called locators. Never heard the term registration pins. 2) The pins are almost always cylinders with a chamfer on top. It's much more robust that a sphere. With molding by pouring the material in, this may not be an issue since there isn't any real pressure building up inside. Injection molding is different and would tear the spheres apart very quickly. The other solid option is a cone shape if it's difficult to line up the halves. 3) I would seriously consider adding a vent hole. Otherwise the air won't all get displaced and you'll wind up with a very porous part. They can be tiny so the final part isn't really effected. Injection molds have these and you can't even see where they are on the finished part. 4) Does the inspect function have the ability to check the knit lines? If using a hot material this is critical in the molding process. 5) You could optionally add ejector pins on the halves to aid in releasing the part. These leave marks though. Please don't take this as criticism, I can't get enough of these. You're series is by FAR the best one out there. Kudos for mentioning mold release and undercuts as well. Anyone starting in molding of any kind really needs to understand these things to be successful.

[@joncue0304]

Your videos are so good I felt I had to become a Patreon supporter. Never done that before. Made an account solely for that purpose. Fantastic work, I sincerely appreciate it.

[@ProductDesignOnline]

Thanks, Jon! I really appreciate you joining my Patreon. Every little bit adds up and will continue to help me create more tutorials and invest in more/better equipment to improve them. Cheers, Kevin :)

[@ProductDesignOnline]

Hi, Jon. Thanks for the feedback. I'm always open to hearing things like this! To clarify, this tutorial was intended to be a very stripped down mold-making tutorial with the focus to be predominantly on Fusion 360's features. Because of that, I have removed industry terminology and tried to keep it at a basic level that a hobbyists could understand and use for small projects (3d printed). I do hope to eventually create some tutorials or a course that is more specific to Injection Molding. I have some experience designing and manufacturing for injection molded parts...although it sounds like you have more than me! I may have to pick your brain if I get around to making a tutorial for it. Thanks again for taking the time to leave and share this valuable molding info! Cheers, Kevin :)

[@joncue0304]

I see what you mean. Makes a lot of sense to do it that way. I would be happy to help any way I can, and I'm never to proud to admit when I don't know something 😂

Great video! It’s great for somebody who hasn’t had any experience in the industry. I’d love to see how you deal with more complex forms of moulds. Detailing mould design features in detail. I’d love to see some permanent moulds that feature some gated delivery, part removal pins or some sort of other industry standard procedure. It would really compliment the already great video here, staging your tutorials so they utilize a previous tutorial part on your channel.

Hello, thanks for the great video! Is there a way to offset the mould and the original body? Let's say I want a 5mm gap between the donut body and the mould. Even if it's not possible to do automatically, how might I do it for simple convex solids?

[@ProductDesignOnline]

You can use "Offset faces" on the solid body to add a gap, after the mold design is cut out.

[@fortifor5410]

Hi, Thank you for the nice tutorial. Just one question, does it need another hole for air to come out? If yes, which part should contain it?

[@TheObscuresausage]

Great tutorial! I do have a question though, would the registration keys require a bit of tolerance around them to ensure the moulds actually fit together nicely? If so how would you ensure there is say a 0.2mm tolerance in the subtracted keys?

[@ProductDesignOnline]

Yep! Use the Offset Face tool to subtract the desired tolerance (0.2mm total does work well in my experience). One note with Offset face is that it will apply to the whole face so you'll actually subtract 0.1 to get the desired .2mm total

[@TheObscuresausage]

Could answer a question only if you have time? I have a solid disk 25mm thick by a diameter of 80mm and I want to put 6 holes 10mm diameter each around the circumference 10mm off the edge. That is the easy part, im just trying set the stage for the part I cant do. Now for the hard part, I need each the hole to lean to the center of the disk 3 degrees and each hole follow the circumference of the disk leaning 10 degrees. can you help? I thoroughly all of your series that you put up. You make it so easy to follow.

[@ProductDesignOnline]

I'm always happy to help! However, I'm not sure I understand the last part of your question. I've got the disk part down and understand that you want to have circles around the circumference... but, can you please explain the degrees in further detail? do you have any reference image(s)? It seems like the 3 degrees and the 10 degrees contradict each other... or are they being applied to different circles? Cheers, Kevin

[@mattgrieve69]

Hi Kevin, a great video. With the two part mould you would need to create a negative of each part of the mould as a first step. How would I do that with the current mould part? For example I have a negative mould-then cut out in wax-use silicone to create your mould part-use your mould part to fill with resin-resin doughnut completed.

[@ProductDesignOnline]

Thanks, Matt. Not sure I'm following your question. Can you post pictures/details of what you're trying to achieve in my community space? bit.ly/PDOcommunity

[@UzunKamis]

Thank you for the great tutorial. I have a question about the registration spheres. Will top and bottom parts coincide? Or should we allow some tolerance gap to have a better closing of the two pars of the mold? Thank you.

[@ProductDesignOnline]

If you plan to 3D print, you'll want to factor in a clearance of approximately 0.5mm to allow the registration pins to align. This can be done with "Offset faces" command.

[@renwycksaludares7926]

@@ProductDesignOnline Hi, do you have a video on how to do these offset faces?

[@theblindspot985]

I had the same question. In practice I have found for my printer that .5mm is a bit loose and .3 is very snug. If the offset plane feature isnt working I would create a sketch on the plane draw a circle with diameter of the sphere and use the revolve tool to cut your two components using the offset tool in the sketch to create the correct size circle.

[@automaticprojects]

Love this series (and your other Fusion tutorials as well). What filament do you recommended for making molds? I've seen some sites recommend PETG, others ABS or ASA? I would've thought TPE or TPU would be easiest to bend apart. I've also printed in PLA, nylons, and PC, so curious what you've found works best for holding epoxy resins? Thanks.

[@ProductDesignOnline]

For epoxy, I've always used PETG or TPU. What I've found matters more is using a 'mold release'. I typically use this one - amzn.to/3HjFPY1 and if you're in a pinch to get a project done you can sometimes get away with using PAM from the grocery store - amzn.to/3zIwhE6 PETG is better to have 'crisp' detail and surfaces, but does not work well for complex parts as you cannot really bend it...so you need to split the mold into 3+ pieces. TPU is the opposite, though you'll lose quality and detail depending on what your'e trying to achieve.

[@automaticprojects]

@@ProductDesignOnline Makes sense and very helpful. Thanks!

[@tepan4d]

[@CadmonShum]

[@Ratkill]

Depending on the material a compression style mold might be best. Same process, but you can extrude the periphery of the mold halves into a male and female complimentary protrusion. This can allow you to exert more force on the media to be shaped without it shooting through the seams.

[@yvesmartin324]

Can we superlike videos? Thanks for the awesome work

[@Zebra66]

Thank you for this and especially for making it short and to the point. Worked perfectly.

[@bhein67]

I found this very informative. If you were trying to split and align the item in the box (for making a sand cast mold) would the process change? Do you have a video on that? (sorry, I'm not sure how to search your video library). I plan to be making brass and aluminum flywheels approximately 4" in diameter and 3/4" thick with features on both sides so a 2 part mold is required. If I knew how to link to a video I could send you an example of the models I build if it would help explain this. I really am enjoying your videos. You are very good at explaining what you are doing in a simple manner for those of us that are "technologically challenged" Cheers from Canada

[@ProductDesignOnline]

Hi, bhein67. Depending on your model, you may need to make a 3-part mold. It really depends on the shape, as any potential "undercuts" would require additional ways to remove the mold so you don't mess up the object.

[@Master2master]

how would someone add tolerances to the registration pins? Wouldn't it be better to have some offset in those spherical cuts?

[@ProductDesignOnline]

Hi Doug. 1. Click on the doughnut file link a360.co/2qfRsZx 2. Click the blue download button. Select Fusion 360 Archive file type and then type out your email. 3. Download the file from your email link 4. Open up your data panel in Fusion 360 (grid icon in the upper lefthand corner) and then select the blue upload button. 5. Select the doughnut file from your downloads folder and then hit "upload." Once uploaded double click on the file to open it up. Here's a video on uploading files - kzbin.info/www/bejne/ioenYYyim6ydg5I Let me know if this clears it up! Cheers, Kevin :)

[@douggrant4008]

That was interesting...I imported it and the did a drag and drop to the design panel. It came in exactly like the others - standing on the edge. Then I watched the video and tried double clicking instead of drag-and-drop and it was in the correct orientation. Why is that?

[@ProductDesignOnline]

@@douggrant4008 I think I know what may be happening. What is your default modeling orientation? I'm guessing you have the Z-axis set to be up? In the doughnut file, the Y-axis was set to up, which could explain why when you open the file it's sitting at the right orientation, but when you insert the doughnut into your current design the object is on its side. Let me know if that was it! Cheers, Kevin :)

[@douggrant4008]

Yes, that is the problem. Is it better to leave it that way in Fusion360 and change it in the slicer, or should I change my preference in Fusion? Or, doesn't it really matter?

[@ProductDesignOnline]

@@douggrant4008 It really doesn't matter. Fusion 360 used to have the default set to Y-up, however, they recently changed it to be Z-up. I try to stick with defaults so it is easy for everyone to follow along, but that's why my older tutorials will have Y-axis up and the latest ones have Z-up. If you're mainly planning on 3D printing then it wouldn't hurt to have everything oriented with the Z-axis up... just one less step (rotating the model) when you get to your slicer. Cheers, Kevin :)

[@ProductDesignOnline]

Correct!

[@johnvaldes2165]

Great tutorial. I was wondering how would you make a mold for a complex piece? I want to for some statue figures that have one leg bent other straight.

[@ProductDesignOnline]

Thanks, John! Sounds like you'll need at least a 3 part mold (or more pieces) depending on how the leg is bent. Essentially, you can follow the same process, cutting in 2 or more directions at once. I'll have to do a more complex mold tutorial at some point.

[@Swarm509]

I suggest looking up tutorials from prop and cosplay makers online. There are a number of good tutorials on complex mold making practices that work best. Take those and you cam then apply what you learned form this tutorial to that. From my experience you will be wanting to make a flexible master mold so it will be a multi part process. Lots of ways to do this though, and after a while you just have to learn from experience... good and bad!

[@dariacompati8070]

Hi! I made the top invisible but you still can see its ghostly shape, and no matter how I turn the bottom part I can't place a sphere on the top of the bottom - it ends up on the top's top.

Hi, paranajape. The Donut file was actually built in another 3D program.

You can use "offset faces" to offset them a defined amount away from the tool or original part

[@vincepugliese911]

Further to my comment above (or is it below now?): As already alluded to you may wish to break the symmetry inherent in the registration pins for better location. Might I suggest converting one of those spheres into a cube? Also you should model an outlet port so that the air has somewhere to go as it is displaced by the mold material. Again thanks for an amazing series of videos?

[@vincepugliese911]

Make that an exclamation mark!

[@ProductDesignOnline]

haha. Thanks, Vince! I agree, making some different registration marks (shapes) would definitely help! Thanks for watching. I'm glad you're enjoying the videos in this series. For more free content please hit Subscribe and share my videos with like-minded people. Cheers, Kevin :)

[@keithallen6004]

how did you create the icing on the Donut?

[@jcv71]

This is weird, but after I create the rectangle and extrude it just like you did, it doesn't allow me to select the extruded rectangle from the Target Body. I can only select the Tool Body (the Doughnut). Why is this?

[@julmjur3752]

i just made a mold that doesnt need to be split it is a cookie mold and when i made a mold with the combine tool and the new component is now the final mold when i rcport it to cura its just a hockeypuck.. and i dont know what i did wrong i tried several times but no result :(

[@Prof.Polymath]

Not sure why but my body wouldn’t split using this due to an intersection error?

[@michaeld954]

i imported an stl model and im trying to make a mold of it but it will not let me select the model when combining

[@ardianmusliji8349]

Hey what about the part about print tolerence, we cant print exact dimensions and expect parts to fit

[@ProductDesignOnline]

Hi Ardian - great question! For this demo the mold was just for fun, so I was not concerned about tolerances. If you're looking for exact dimensions then you will have to do some tests. The tolerances really depend on what type of 3D printer you're using, as they vary drastically from consumer level printers to commercial grade printers. Cheers, Kevin :)

[@ardianmusliji8349]

@@ProductDesignOnline thanks for the reply you're awesome! I was just hoping to maybe see which way you would go about it when it comes to modeling tolerences. My tolerance is 0.06mm

[@ProductDesignOnline]

@@ardianmusliji8349 Unfortunately, Fusion 360 doesn't currently offer an easy way to do tolerances while using the split or combine tools. If you're planning on 3D printing, I actually recommend adding tolerances in your 3D printers slicing software by slightly scaling the mold. Alternatively, you can scale the object in Fusion 360 before you go to create the mold. Cheers, Kevin :)

[@krystiankosowski4617]

You can set tolerance on cura and other slicers different on two half of object

[@tristinkurtz2394]

hey so I'm having a problem where its says the plane isn't in contact with the object I'm trying to split. Do you have any idea what would cause that to happen?

[@ProductDesignOnline]

Hey Tristin. Are all of your bodies turned on in the Fusion 360 browser? Make sure the lightbulb icon is lit up. If that's not it, then please share your file and I'll take a look. Share your public link as a reply to this comment. Here's a video explaining how to share a public link - kzbin.info/www/bejne/aInVlKWai5JrgtU Then, please write a separate comment letting me know you've replied with a link because KZbin flags most links and I don't always get notified. Cheers, Kevin :)

Hi, Kevin 11:11 I'm wondering what "registration keys" is

[@ProductDesignOnline]

Great question, CHO성진. In mold-making, a registration key is a shape that is intentionally added to help ensure that all the parts of the mold line up correctly after taking it apart. It ensures that each time the mold pieces fit back together and that they don't slide apart in the mold making process (however, usually a rubber-band or latch is required to hold the pieces together). One thing to note - in this video I simply made half spheres...but you could realistically make the registration keys any shape that allows one piece to be taken apart from another. Cheers, Kevin :)

[@devstefancho]

Product Design Online Thank you! I understand it so useful information

[@ProductDesignOnline]

@@devstefancho You're welcome :)

[@fyzobaba]

Why can't I select the inner structure which is the tool bodies when I want to combine?

[@sammewhinney5967]

I tried giving more register keys to the top and bottom components. I split the top and bottom halves to quarters and they gave me an error saying "There was a problem combining geometry together." what should I do?

[@ProductDesignOnline]

Hi Sam. This error is typically caused by some sort of geometry not being fully closed. To check this, you can turn off the design history. Right-click on the top-level component in the Browser > Select "Do not capture design history". Then, while in the Design workspace, select the inspect dropdown menu > validate. Using the validate feature will help you verify the quality of the bodies. If it finds any errors it will attempt to repair them by stitching them together. Let me know if that helps. I'd be happy to take a look at your file if you'd like. Cheers, Kevin :)

[@thomaswahahauw560]

What about a compression mold where we need a pushing part

[@wizardOfRobots]

How did you make the doughtnut though!?

[@mdtanjeebhossain6708]

Did you make the doughnut using the sculpt workspace

[@ProductDesignOnline]

Nope, it was made in Blender :)

[@mauriziopagnotta8873]

Salve bel video! È possibile farlo con una mesh come oggetto? Nel senso che al posto della sua ciambella in solido ci fosse una mesh.... grazie mille. Perché ho un oggetto in mesh e volevo creare lo stampo per iniezione.

[@ProductDesignOnline]

Ciao Maurizio. Questa è un'ottima domanda. Sfortunatamente, i file Mesh non possono essere utilizzati con lo strumento Combina. Dovresti prima convertire la mesh. Puoi imparare come convertire la mesh, qui - kzbin.info/www/bejne/ppi6iImZgpqMgLs Saluti, Kevin :) English: Hi, Maurizio. That's a great question. Unfortunately, Mesh files cannot be used with the Combine tool. You would need to convert the mesh beforehand. You can learn how to convert the mesh, here - kzbin.info/www/bejne/ppi6iImZgpqMgLs Cheers, Kevin :)

[@mauriziopagnotta8873]

Purtroppo ho un file con molti dettagli e in fusion usando il reduce mi spariscono tutti i dettagli ho provato a convertirlo con il programma free cad ed esportato in file step ma quando lo vado ad importare il file in fusion non riesco a lavorarlo perché è troppo pesante e non è molto dettagliato

[@ProductDesignOnline]

Learn to pronounce Grazie per il chiarimento. L'opzione migliore sarebbe quella di utilizzare un programma basato su mesh per creare lo stampo. Suggerirei "Blender" o potresti crearlo in "Autodesk Meshmixer". Saluti, Kevin :)

[@mauriziopagnotta8873]

Ok grazie mille molto gentile.... ma una soluzione per far sì che il file solido che ho con molte facce che lo rende pesante,non c’è un metodo che le unisce tutte e rende l oggetto con una sola faccia per renderlo più leggero? Perché così quando vado a selezionare un punto sull oggetto mi seleziona quella minima parte invece mi serve che quando vado a selezionare in qualsiasi punto mi seleziona tutto. Grazie mille

[@ProductDesignOnline]

@@mauriziopagnotta8873 Sfortunatamente, i file mesh non funzionano bene con Fusion 360. A seconda dell'oggetto potresti essere meglio se riesci a ricrearlo da zero. Altrimenti, sarà più facile lavorare con un programma mesh. Saluti, Kevin :)
