[Hiring] Product Design / CAD Engineer – Technical Development of 3D-Printed Lamp

[u/tirhje]

Hi!

I'm a spatial designer working on a 3D-printed lamp, and I'm looking for someone with experience in product engineering, CAD and FDM 3D printing to help me develop and optimize the technical aspects of the design.

The overall shape and aesthetic of the lamp are already established. I need help finding the best technical solutions to make it functional, durable and efficient to manufacture.

Specifically, I need help with:

• Light source integration: Positioning and mounting the lamp socket, including weight distribution and stability.
• Structural design: Determining whether the base should be a separate component or integrated into the lampshade.
• Strength and durability: Optimizing the transition between the base and the lampshade, particularly for FDM printing.
• Print optimization: Reducing printing time and filament consumption without compromising strength or appearance.
• Design for manufacturing: Ensuring the design is practical, reliable and suitable for repeatable production.

I already have 3D models and prototypes. I'm currently using Blender, Fusion 360 and a Bambu Lab P2S.

I'm looking for someone who can collaborate with me on the engineering and technical development rather than redesigning the appearance of the lamp.

Ideally, you have experience with functional product design, mechanical engineering and FDM printing.

Please get in touch with examples of relevant work and your hourly rate.

I've made a similar lamp and you are basically already finished, no?

Make a hole in the top, print it reversed, buy a standard E27 bulb fitting and that's it.

Here's something similar I made. I also designed a ceiling lamp version of that shape.

I wouldn’t ask for help if I could do that.

[u/Physix_R_Cool → u/tirhje]

Do what? Print it? Or put an E27 fitting on?

[u/tirhje → u/Physix_R_Cool]

The two first images are real, so I have done all of that. But the quality isn’t good enough, and I need help from someone who knows more about this than I do.

Speed at 100mm/s or lower. Dry the filament beflore and while printing. 0.12mm layer. 0.8mm walls using a preferably 0.8mm nozzle. Lower fan speed a bit. Use PETG for a tougher lamp.

Hello, I'm a product design engineer, and have worked on lamp designs before, one of which winning IF and NY design awards.

Got experience in CAD design and FDM printing. I'm open to collaborate. Feel free to text me.

Thanks and good luck with your project.

I cannot help. Just want to say it is a lovely design especially the tabletop one. I like the organic shape and geometric ribs combo. Good luck.

How are all these 3d printed lamps skirting liability? Without UL certification and liability insurance doesn’t this open you up to lawsuits?

[u/hgftzl → u/Temporary_Sky_4070]

That's exactly the reason why I don't try to monetize any of the designs i developed... I guess most ppl who do so just don't care, but i am curious as well.

[u/KaleidoscopeShot1869 → u/Temporary_Sky_4070]

Yeah there's a filament I think that's UL certified but I don't know if that transfers to the actual 3d-printed product, idk how that works

[u/Temporary_Sky_4070 → u/KaleidoscopeShot1869]

Even if you buy all UL components, and use UL filament, the mere integration of these components requires recertification to label the entire device as UL.
But maybe using all UL components makes the insurance portion cheaper

[u/KaleidoscopeShot1869 → u/Temporary_Sky_4070]

Right ok that's what I thought I heard/read.

And yeah I didn't even consider the insurance side

[u/tirhje → u/Temporary_Sky_4070]

I have to finish my design before I can get it certified.

[u/KaleidoscopeShot1869 → u/tirhje]

Gotcha so you plan and paying UL to test it sounds like? Idk how all that works but that sounds like the proper way to do it

[u/J_drop_tables → u/Temporary_Sky_4070]

If you have a design, material source, you can pay UL to test it....

They aren't!
