I second this. It's the best compromise in my opinion because unfortunately, you still have to title your videos for SEO, if you don't want your videos to get buried by the algorithm. Make the first part of the title as clickbaity as you want, but include the episode number at least so people know what they're clicking on. for example: "This took WAY too long! | Electric Porsche Build Ep X"
@ribtips305 I know this, but a new viewer might want to know some more details at first glance, how deep is the build into etc. providing a little detail wouldn’t harm, also it would make searching for the videos easier
The Design Studio collaborating with Jeremy here on the project👋🏻 First and foremost, the entire team at IJ Design Studio is thrilled and honored to be a part of this incredible journey with the Electric Supercar channel. Jeremy has made significant contributions to the community, inspiring many to embark on their own automotive projects. We've noticed several recurring questions in the comments section, so we thought it would be best to address them all here. Q1: Why 3D print the part itself instead of the mold? A: 3D printing molds for composite fabrication, such as carbon fiber and fiberglass, is indeed an innovative and widely-used approach in the automotive industry. However, we chose to 3D print the panels themselves for two key reasons. First, the complexity of the design: even with the most skilled and advanced composite fabricators, some designs are simply too intricate to be created using traditional molding methods. Given the thorough nature of this project, we aimed to create the best-performing part that seamlessly retrofits the existing chassis without compromising design, integrity, or functionality. At our studio, function is as crucial as form. For example, the lighting elements in this car are integrated within the rear bumper, avoiding unsightly cables. Even though this detail is rarely seen, it exemplifies our commitment to meticulous design and creative problem-solving. Q2: Why 3D print the parts instead of CNC machining a plug for molding? A: While 3D printing is relatively new compared to traditional reductive manufacturing techniques, it offers significant advantages, allowing us to create complex shapes and details that are nearly impossible to achieve with other methods. By leveraging this technology, we were able to realize the perfect design for this project. Q3: Why didn't you design locking mechanisms such as dovetails or keyways between the parts or flanges? A: We certainly could have incorporated locking mechanisms. However, since we are not printing the parts in-house (where we can control tolerances to avoid issues like shrinkage or oversizing), we opted to keep the parts simple. This decision also ensures better adherence to the printing bed, reducing the risk of errors. Q4: Wouldn’t printing it in multiple pieces reduce the part's structural integrity and make it more prone to breaking? A: It's true that using FDM technology to print parts that will be subjected to mechanical stress isn’t ideal. The layer-by-layer printing process can create weak points that are prone to delamination and UV degradation over time. However, by reinforcing the parts with composite materials, we can significantly increase their stiffness and strength, often surpassing that of traditionally molded parts. Q5: Isn’t this design too heavy for a rear bumper? Rear bumpers typically weigh much less. A: While the weight of the bumper is higher than anticipated, this is partly due to unavoidable changes in the printer settings. However, even with ideal settings, this bumper would still be heavier than a standard injection-molded or composite bumper. Why? Because this isn’t just a rear bumper. Typically, rear bumpers are cosmetic pieces designed to conceal safety structures. In this project, we’ve made the bumper an integral part of the car’s performance and safety features. For instance, the car’s overall length has been increased to accommodate the battery pack, which needs to be protected in the event of an impact. We’ve added an additional impact structure to create a safety cage around the battery pack, enhancing its protection. Moreover, the bumper supports the rear wing (which generates considerable downforce) and houses the taillight electronics, making it a multi-functional component rather than just a "regular bumper." Q6: Wouldn’t it be better to stick to the original Porsche design and parts instead of redesigning them? A: While using existing parts would have been easier and faster, it would undermine the ambition of this project. Despite Jeremy’s humility, this build is on a completely different level compared to others. Although it’s based on the Porsche Cayman’s highly capable chassis, this car will be transformed into something entirely new, aiming for hypercar levels of performance. We respect the spirit of Porsche and have incorporated elements of their latest design language as a nod to the brand, such as the rear light bar. However, this car is not trying to be a Porsche; it is its own unique entity, and the design reflects that identity. Feel free to ask any further questions. We’ll do our best to answer them. Cheers ❤
Next time, 3D print some keyways between the parts (kind of like 3D puzzle pieces) so they are self-aligning and you don't need to worry about the popsicle stick method (plus, the keyways add extra surface area and support in different directions, so you aren't relying only on the glue to prevent shear along that plane). You can even design the keyways to accept some 1/2" bar stock for extra rigidity if needed.
@rthomp03 Yes, I was wondering why the 3D printing guys working with him didn't offer this solution to him, that would totally eliminate his need for cross sectional struts like he talked about too
The designer gave this reason: "Q3: Why didn't you design locking mechanisms such as dovetails or keyways between the parts or flanges? A: We certainly could have incorporated locking mechanisms. However, since we are not printing the parts in-house (where we can control tolerances to avoid issues like shrinkage or oversizing), we opted to keep the parts simple. This decision also ensures better adherence to the printing bed, reducing the risk of errors."
For the next large 3d print you need to bond pieces together I’d recommend doing flanges (either perpendicular or overlapping) gives a lot more surface area and you can get a bond nearly as strong as the layer lines or stronger depending on the print material. I personally like 1/2-1” overlapping flanges and I’ll usually use solvent bonding solution in addition to plastic welding the back side with reinforcement mesh. Ends up being very strong and much easier to ensure the visible surfaces line up properly and make a mold as the plug ends up far more rigid
that looks so awesome! one suggestion: use angled wirecutters to cut those staple pins. because when you wiggle those pins out, you might weaken those staple joints a little. love your work, been following you since the K1 Attack build. Wish I could work with you.
Wow, just wow. I do think printing a mold would be better, but this way you get to see final product and plan the molds better. Diffusers are normally attached separately, so that would be a good place to start. The front will be sick as it matches this end!
Nice work integrating the hot staples. We use them in the Collision Repair world quite a bit. They work great! 👍 Edit: HEAT SET threaded inserts work GREAT on 3d printed parts for screwing pieces together.
Might be a good idea to add locating features to the join planes (such as holes and pins) to reduce alignment errors especially on such large pieces. Loving your efforts and enthusiasm to rebuild yourself and expand your repertoire
Nice! Two remarks though; 1. I hope you have a place to send all that 3D printed material to for recycling once you're done (though you'd probably need to clean it up a bit as it would have to be pure. 2. Those 'moving' indicator lights look nice. It's my pet peeve that they always work like that. Where it only makes sense to animate it when used as indicator light. But blink steady when used as warning lights. Pretty please, try to implement that!
I have done a bunch of big prints not quite that scale. Simplest method to make alignment easy and strengthen joints is to use metal rods or bars. It is easy to print holes in precise locations in model. Can always drill out if too tight, though I usually print some tests to get right hole size for snug fit. Have used 1/8th steel rod for small joints up to 1/2 electrical conduit from Home Depot for large joints. Feel it would make it much easier for you. Can also recommend heat set threaded inserts and machine screws for joining parts. You can tap printed holes but have to have the whole the right size(printed or drilled) to not break the part due to expansion when tapping. Mechanical fixings are usually way easier and more reliable than glue on 3D printed parts in my experience.
Hey, I love what you are do here. It's been awhile since I've done any CAD work but, here's my idea anyways... 😀 Have you thought about putting holes in the mating surfaces for alignment pins? Using a chamfer at the bottom and top of the holes would eliminate need for extra 3d printed supports for the holes and give somewhere for the glue to ooze out of the hole without getting onto the flat matching surfaces. The way I'm picturing this is creating a subtraction part shaped like the holes you want in the main part. Then cut and pasting them wherever you want an alignment pin. The planes in the main part used from separating the big part into smaller parts could be used a guide for where the place this subtraction part. Idk if I make any sense but it seems like this would be easy to do in CAD and make putting the parts together easier?
This looks great! Two items though. First, I really hope you're looking at building more modularity into the whole unit somehow. Just imagine the smallest little piece breaks on the finished bumper on the road, you'd have to replace the entire thing unless you make it more modular! Second, are the tail lights large enough to be legal? They seem super thin. Other than that though, really looking forward to seeing how it all comes together!
I love this project and everything you do, thank you for sharing all of this with us! The plastic welder is amazing, those little staple things are cool. Now, I know nothing about 3d printing, but for a big piece like this, wouldn't adding some male/female joints save a lot of the work you had to do in this video for creating stable unions? **EDIT** I continued watching the video, and I see that this bumper is just a placeholder. So maybe the extra modeling work wouldn't be worth it, especially if you're just going to be using it as a structure for shaping the finished product.
Love the bumper you guys made it is so sharp! If you have rigidity problems maybe look at using another 3D print to make a buck that you can use to make some carbon fiber skins and glue them on the inside. Not thick heavy carbon.
With the plastic welder staples, I'd recommend turning the staples so that they're parallel to the seam as you'll get more coverage with each staple since it has more intersections with each zigzag. Applying them perpendicularly only gives the staple the one intersection at the seam. Since it only crosses at the one point.
Next time if you have interior surfaces that you don't care about, you can create flats that allow you to clamp pieces together. In addition, you can instead of creating flat slice planes make interlocking puzzle piece splits OR "staples" you can insert / press in.
JB Weld has two products specfically meant for plastics. Plastic Bond, and Plastic Weld. The Weld like the Goop has a solvent that "melts" the surface. I use the bond on PETG prints all the time. I have had layers fail before the bond. I saw you used regular JB Weld
Surprised to see Stirlingkit sponsor this video. Being a common user of their store. In the process of building a skyline RC by using a engine i bought from their store some time back. With them being like a wholesaler of scale and model engines. A lot of companies they work with can give them bad rep. But their customer service is amazing.
Really great design! I think the Acrylic light bar is too recessed inside the bumper, though. I think it should stick out more. Also, I think it is a good idea to think about maintainability and access before the design gets too complicated. Don't make things difficult for yourself.
You could also make it a shell and used spray fibreglass reinforcement on the inside and body work the plastic but very inspiring as someone with a huge printer you got my brain ticking now 😂
For such a big project I think it would have been best to use dowel-pins (instead of those sticks) Also 2 component glue would IMO been the better choice. It comes with self-mixing tubes which make applying much easier. They also sell them with different curing times which would have given more time to adjust those parts and assembly
Since you're using LEDs for taillights you reminded me of something I saw decades ago in I think it was in Mechanix Illustrated. And LEDs would make it easier to do. They showed a car and the taillights were designed to turn red when you were braking. Green lights for when you were accelerating. And when you were coasting they were amber. You can tell exactly what the car in front of you is doing. Accelerating, Coasting or Braking.
Street Bandito integrated some flanges into the bits for the electric Z. He was then able to use small clamps to keep them together while the glue cured
Looks awesome! Any thoughts about splitting it into multiple pieces? I worry what happens when someone hits a shopping cart into it, replacing the whole thing if it gets damaged seems nuts.
It may be too late at this point, but I'd consider making the entire thing out of multiple pieces such as the diffuser being one large piece, the side vertical aero pieces being separate, and then the rest of the bumper being one piece. I might even suggest the upper spoiler section being it's own separate piece. This would help making the mold for the composite material way less complicated. If you damaged the diffuser portion, you would just need to replace that portion versus the ENTIRE rear bumper.
Try some 2-Part plastic epoxy. Similar to products like Gloop, 2-part plastic epoxy has a solvent that causes the plastic to become pliable, but some have an extended cure time to allow more working time. When cured, it offers 3000+PSI strength... the surrounding plastic material will break before the joint does. Loctite, Gorilla, and JB Weld have some of these. (must be used in well-ventilated area)
it's gonna be almost impossible to make a mold out of this. You must consider that at the design phase. mold making has certain requirements. (draft angles, parting lines etc) that certain cad programs can help you with . if someone asked me to copy this bumper, i would flat out deny.
You should have collaborated with an experienced woodworker, those guys can figure ways to clamp pretty much anything. Nice work tho, bumper looks cool!
Great project! When I work on car parts, I use NOVOL CARBON 300 - carbon fiber putty. You’ll be amazed at how well it bonds with 3D printed parts and decorations, creating a super strong and lightweight finish
Looks cool, but I personally would have gone with carbon fiber. It would have taken a bit more time depending on how it was done but would have probably been stronger and 1/2 the weight.

Cmon leave him alone, much more thought went into for views/show than actually doing the stuff.

I cant stop looking at this bumper w/o being reminded of a 959 rear end. What a cool project. Thanks for sharing
Glad you liked it!
That looks seriously amazing!! Great work!!!
Thanks so much for the support!
This was very fun to see the first 3D printed body part come together! It really looks like a wild, exotic design. Congratulations!
Thanks Dean!
The bumper looks awesome. Go with thin panels (5mm), and use 0.5" steel rectangular tubing for support. Then you can just fiber glass over it.
Nice!
Nice bumper. You know, Modix can print that entire bumper in one print? Their largest printer might be able to print your entire car.
This looks so cool!! can't wait to see it completed
Me too!

WOW! That's the most beautiful Porsche bumper l have ever seen.
@richardike2342 thanks Friend!
Keep going! Can’t wait to see the full body on the car!

Looking at the first parts being glued… you could have printed some features that interlock, instead of just a flat surface to glue
Wow this is going to look amazing when done😮
Thanks for the comment!

That is really impressive work. Can you maybe do a video on how you sliced everything?
Love the bumper you guys made it is so sharp! If you have rigidity problems maybe look at using another 3D print to make a buck that you can use to make some carbon fiber skins and glue them on the inside. Not thick heavy carbon.

you can have the joints overlap to aid the structure and also have enough area for the bonding agent to bind
Next time if you have interior surfaces that you don't care about, you can create flats that allow you to clamp pieces together. In addition, you can instead of creating flat slice planes make interlocking puzzle piece splits OR "staples" you can insert / press in.

I think the Acrylic light bar is too recessed inside the bumper, though. I think it should stick out more.
Also, I think it is a good idea to think about maintainability and access before the design gets too complicated.
Don't make things difficult for yourself.

Also, I've used a 3d pen to join two printed pieces - first I would melt the edges to create a "valley", then lay a bead of the same material
I would love a custom 911 997.2 rear bumper with the 992 style LED rear light bar!
Looks awesome! Any thoughts about splitting it into multiple pieces? I worry what happens when someone hits a shopping cart into it, replacing the whole thing if it gets damaged seems nuts.
I will be making molds for carbon fiber parts
Good shit man… I’ve been working the buck for my rear clam for the last month, maybe month and a half and it’s only 80% there…
You have to make these parts to sell to 987 and 718 owners!!! i would buy the kit once it is done!
Nice!
Panel bond would’ve been far superior
Badass 3D printing job! Do you have the info anywhere for that Tetris song? Really liked it but can't seem to find it.
That’s a crazy design
✌️
It may be too late at this point, but I'd consider making the entire thing out of multiple pieces such as the diffuser being one large piece, the side vertical aero pieces being separate, and then the rest of the bumper being one piece. I might even suggest the upper spoiler section being it's own separate piece. This would help making the mold for the composite material way less complicated. If you damaged the diffuser portion, you would just need to replace that portion versus the ENTIRE rear bumper.
I probably will
Sick !
✌️
Try some 2-Part plastic epoxy. Similar to products like Gloop, 2-part plastic epoxy has a solvent that causes the plastic to become pliable, but some have an extended cure time to allow more working time. When cured, it offers 3000+PSI strength... the surrounding plastic material will break before the joint does.
Loctite, Gorilla, and JB Weld have some of these. (must be used in well-ventilated area)
Good call
Fast set methacrylate adhesive would work great
Thanks for the comment!
it's gonna be almost impossible to make a mold out of this. You must consider that at the design phase. mold making has certain requirements. (draft angles, parting lines etc) that certain cad programs can help you with . if someone asked me to copy this bumper, i would flat out deny.
You should have collaborated with an experienced woodworker, those guys can figure ways to clamp pretty much anything. Nice work tho, bumper looks cool!
That would be cool!
you can print some jigs to hold the pieces in place while you glue/clamp.
Good call
The bumper looks amazing. But from engineering and assembling perspective I would probably separate it in couple pieces. But good job
Great project! When I work on car parts, I use NOVOL CARBON 300 - carbon fiber putty. You’ll be amazed at how well it bonds with 3D printed parts and decorations, creating a super strong and lightweight finish
Thanks for the tip!
Really nice video
Thanks a lot
Adding wood dowel holes on both sides would be the best idea so far…
Noted!
Is your plan to make a mold out of the plastic? If I missed that, I apologize. Looks awesome!
i would actually buy this. if you designed to retro fit 992 lightbar onto cayman ill buy it in a heart beat .
Interesting 🤔
nice but will it hold in speeds and bumps and other stuff ?
Final part will be put of carbon fiber
Looks cool, but I personally would have gone with carbon fiber. It would have taken a bit more time depending on how it was done but would have probably been stronger and 1/2 the weight.
Carbon fiber is the end goal. Going to make a mold from this
👍 nice. I was concerned the plastic might soften in the sun, but if it's just for a mold, then you're one step ahead@@electricsupercar
@@electricsupercar Ah, great job my man, great job! Please post that process, I love working with FRP, CF. and mold making!
Best way to join large plastic is the welder :)
And adding some pins or other features to help with aligning them.
The 100th like!👍 Well done!🎉
Yay! Thank you!
I'm also using 3D scanning to create some small car parts. Could you share which software you use for car body design?
I use SolidWorks
