| Stainless steel Grades | Description | Process | Advantages |
|---|---|---|---|
| 303,304,316.. | Most commonly used stainless steel Low carbon Better weldability and formability | 303, 304L, 316L, 410, 416, 440C, 17-4PH, Nitronic 60 | Household and industrial applications: screws, machinery parts, car headers, food-handling equipment, |
| EOS SS 316L | Most commonly used stainless steel Low carbon Better weldability and formability | 3D Printing (DMLS/SLM) | Medical, aerospace, applications needing corrosion resistance and hardness |
| 400 Series | Martensitic steels are extremely strong and tough due to higher carbon content, but more susceptible to corrosion in certain environments | CNC Machining | Applications that need less corrosion resistance, more hardness, or lower cost |
| 17-4 PH | 17-4 PH Stainless Steel is a high-strength, highly corrosion-resistant material that maintains its durability up to 1100°F. The PH in its name stands for precipitation-hardened, a type of treatment it undergoes to increase yield strength | CNC Machining | Medical, aerospace, applications needing corrosion resistance and hardness |
| 15-5PH | Higher magnetism than 304 and 316 stainless steel Oxidation and corrosion resistance | CNC Machining | Medical, aerospace, applications needing corrosion resistance and hardness |
| Duplex steel | Have a higher chromium content, 20–28%; higher molybdenum, up to 5%; lower nickel, up to 9% and 0.05–0.50% nitrogen | CNC Machining | Household and industrial applications: screws, machinery parts, car headers, food-handling equipment |
| Processes | Lead Time | Grade | Tolerance | Price | Applications |
|---|---|---|---|---|---|
| CNC Machining | As fast as 3 days | 303, 304L, 316L, 410, 416, 440C, 17-4PH, Nitronic 60 | With drawing: as low as +/- 0.005 mm No drawing: ISO 2768 medium | Qty & Precision dependent | Industrial applications, fittings, fasteners, cookware, medical devices |
| 3D Printing | 2-4 Days based on size | SS316L | DMLS/SLM - 0.150 mm | Lowest in market | Functional end use parts. |
| Services Name | Max Size | Min Size | Min Thickness | Undercuts | Radii Depth |
|---|---|---|---|---|---|
| For CNC Machining | Max Part Size: 600 mm | Min End Mill Size: 0.8 mm | Min Wall Thickness: 0.5 mm | Undercuts: Square profile, full radius, dovetail profiles | Radii: Depth: Depth must not exceed 12x drill bit diameter. For end mills, depth must not exceed 10x tool diameter. |
| For 3D Printing | Max Part Size: 500x500x500 mm | Min Hole size : 1 mm | Min Wall Thickness: 1 mm | Min Feature Size : 3 mm | Recommended fillet & Chamfer angles : > 45 Deg |
| For Molding | Max Part Size: 500x500x500 mm | Min Hole size : 0.5 mm | Min Wall Thickness: 0.5 mm | Ribs should be 40-60% the thickness of outer walls and should still maintain draft | Minimum draft angle of 0.5°, or up to 5°, for faces with medium textures |
Think3D has been a great partner for us in supplying COVID-19 test cartridges on-time despite the pandemic challenges. When we came up with a new requirement needing a workforce of more than 25 people, think3D took up the challenge and arranged the workforce within 2 days. I highly recommend think3D for any manufacturing needs.

As a professor doing research on new materials, I needed a strong industry partner to assist us. think3D perfectly fit that bill. think3D team is highly knowledgeable on all manufacturing technologies and the team is very prompt in responding to all our requests. My research has been very successful, thanks to think3D team.

We found issue with one part at the time of assembly and needed a quick replacement. think3D team has quickly responded to our request, redesigned the part and printed it using metal 3D Printing and delivered in 3 days time. The part came out really well and the design was better than that of the actual one.
