Hire the Best CAD Designers
in Turkey

I am a Mechanical Design Engineer specializing in SolidWorks, product design, CNC manufacturing, and design for manufacturability (DFM). I help clients turn concepts, sketches, reference images, or existing CAD files into clean, practical, production-ready 3D models and technical documentation. My background combines hands-on CNC machining experience with mechanical design, so I design parts with real manufacturing constraints in mind — not only for appearance, but also for machining, assembly, tolerances, and production. I can help with: • 3D CAD modeling in SolidWorks • Product design and mechanical part design • Manufacturing-ready CAD cleanup • CNC-machined part design • Sheet metal design and flat patterns • Technical drawings for production • STEP, STL, DXF, SLDPRT, SLDASM, and drawing exports • Tolerance review and DFM improvements • Assembly design and interference checks • Reverse engineering from images, sketches, or existing files I have experience working with CNC milling, turning, sheet metal parts, mechanical assemblies, product housings, fixtures, and production documentation. My goal is to deliver clean, reliable, and manufacturable CAD files that help clients move from idea to prototype or production with confidence. If you need a mechanical designer who understands both CAD and real-world manufacturing, I can help.

I am a professional 3D Jewelry CAD Designer with hands-on experience in both jewelry creation and digital marketing. After graduating in 2021, I gained over 2.5 years of experience managing digital marketing for a jewelry company, including campaign management, product production, photography, pricing, website management, social media ads, SEO, and Google Ads agency coordination. Building on this experience, I pursued Matrix 9.0 jewelry design training and have been creating high-quality 3D jewelry designs ever since. I specialize in custom rings, necklaces, earrings, and bracelets, providing production-ready CAD files and realistic renderings. My combined knowledge of jewelry production and marketing ensures designs that are not only visually stunning but also market-ready.

www,celalettintoprak,com I design real products that get manufactured - not just 3D models. Manufacturing-ready CAD, prototyping, and Design for Manufacturing (DFM)-driven product development for industrial and consumer products. I’m an Engineer and Industrial Product Designer focused on manufacturing-driven product development. My background spans automotive, industrial, and consumer products, where I’ve worked as a Product Developer, Designer, and Technical Lead in production-oriented environments. I don’t approach projects as isolated design tasks. I approach them as systems that must survive prototyping, manufacturing, assembly, cost pressure, and real-world use. 📐 What You Can Expect Working With Me: - Clear, structured CAD suitable for iteration and production - Design decisions informed by manufacturing reality - Practical communication with engineers, suppliers, and manufacturers - Honest feasibility feedback (go / no-go when needed) - Designs meant to be tested, not just rendered 📐 Core Capabilities: - 3D CAD modeling (Siemens NX) - 2D technical drawings (AutoCAD Professional) - CNC, laser cutting, and sheet metal preparation - Injection molding–ready part design - Fixture, bracket, and assembly design - BOM creation and production planning support - Reverse engineering and scan-based modeling 📐 Injection Mold & Manufacturing Experience I have hands-on experience designing plastic injection molds and mold-ready parts, including projects for automotive and food-related products. ⚙️ I’m familiar with: - Injection molding–ready design, Core / cavity logic - Draft angles & wall thickness optimization - Parting lines and shut-off surfaces - Shrinkage and material behavior - Gate concepts (hot runner, valve gate) - Collaboration with mold makers and CNC shops - Design for Assembly (DFA), production validation - Engineering-driven product development - Long-term product roadmap support My focus is always on tool longevity, cycle time, surface quality, and cost efficiency. 📏 Typical Projects I Work On: - Automotive accessories and aftermarket products - Mechanically complex plastic or metal parts - Prototyping-heavy product development - Production validation before tooling - Redesigns for cost reduction or manufacturability - CAD clean-up and production conversion 📌 Primary CAD Tool: Siemens NX, AutoCAD and Geomagic Design X I work primarily in Siemens NX, which is widely used in high-end automotive and industrial manufacturing. I can deliver clean, fully editable STEP / STL / Parasolid files, and I regularly convert and work with SolidWorks, Fusion 360, Rhino, SketchUp, and scan-based data. If you use SolidWorks or another CAD system, this is not a limitation — deliverables are always production-ready and compatible. 📌 If you need more than a modeler—someone who understands how products are actually built and scaled—I can support your project from concept to production readiness.

I help startups and companies turn product ideas into manufacturable products that can be prototyped and mass-produced. My designs gained my clients 20,000+ USD in crowdfunding. I helped with dozens of patents and launched real ecommerce products on Amazon with 4-5 star ratings, which sold and generated over 1M+ revenue. I work with individuals, large companies and startups. Why Clients Choose Me: ✅Turn-Key Solutions: From concept to prototype, and all the way to mass production, I am with you at every step. I have done this before. I will guide you from start to finish. ✅Long-Term Partnerships: 80% of my clients become repeat customers, entrusting me with their ideas time and again. That is because I specialize in Design for Manufacturing and create realistic products that work ✅Efficient Workflow: My process helps my clients go from their dream product to a first sample of it made on a real factory in the shortest time possible. How? Detail-oriented and manufacturing-oriented design. And rapid design changes. ✅ Experience. I already helped tens of people turn their ideas and inspirations into real products that they can sell in ecommerce, get crowdfunded or patented. And I can help you too Client Success Stories: -I once worked with a startup struggling to bring their innovative power equipment concept to life. They had an impressive idea for a cost-efficient pellet-boiler but they didn't know how to make a physical product. I made a complete design for them and guided them to make a prototype and later achieve investor funding with my design. -I helped a military company create an innovative hybrid unmanned ground vehicle from scratch. Some of the solutions I offered there have never yet been implemented in the market. - I helped multiple startup entrepreneurs with small budgets with kickstarter campaigns to earn over 20 000 USD in donations to bring their ideas into market.
