Given that I've designed and successfully produced a wide range of products, including some functional appliances in my 10-year career, I've gained significant knowledge about not only SolidWorks designs but also practical requirements for 3D printing. My proficiency in Solidworks uplifted the designs I once tried from scratch till what do my clients envisage.
Not only do I know the demands of a significant project like yours, but also have resources to meet them. Since your project entails making a working appliance, which will effectively dispense rice to a bowl, requires thorough understanding efficient gravity-fed technology and compliance to specific material - PLA for the essential parts. Over time, I’ve amassed satisfactory knowledge about materials used in 3D printing – PLA being one of them, which is perfect for your project.
In conclusion, with your bid background and my proficiency in Solidworks, extensive experience in designing functional appliances effectively and safely using PLA in 3D-printing, you're assured your product will be designed at utmost precision and delivered error-free to suit your need. With me, not only you are hiring a freelancer but an artist eager to manifest your vision into reality. Thank you!
