TIPS WITH TONY: Prototyping with Hard Metals

Last week we discussed prototyping with soft metals like aluminum, copper and brass, so this week we turn our attention to hard metals and processes (3D printing, CNC machining and injection molding) used for rapid prototyping in low volumes.

Hard metals that are offered in three different manufacturing processes at Proto Labs: direct metal laser sintering (DMLS), CNC machining (CNC) and metal injection molding (MIM).

Stainless Steel
Stainless steel (SS) is one of the most widely used metals in our material library and is available in three different grades and all three services: 3D printing, machining and molding.

  • 304L is only available for machined parts and offers a higher tensile strength and good corrosion resistance while offering a slightly lower price than other stainless steel materials.
  • 316L is available in machining, industrial 3D printing through direct metal laser sintering (DMLS) and metal injection molding (MIM). 316 offers an improved corrosion and chemical resistance over 304 while offering a high temperature tolerance.
  • 17-4PH is also available in all three manufacturing methods and offers a higher yield and tensile strength with good resistances to corrosion. 17-4 also offers a higher magnetism of all our SS offerings.

DMLS lugs help build the ultimate urban utility bike

San Francisco is an ideal backdrop for a bike culture to thrive. Its temperatures remain consistently mild year-round, and its landscape seamlessly blends hills, streets and shoreline. Bicyclists commute to work, run errands, transport groceries (and their kids), and climb rugged bike paths to Bay Area overlooks. And that’s just a Monday.This fusion of task- and recreationally minded biking activities amidst the natural and man-made architecture of San Francisco was the inspiration behind Huge Design’s recent entry into Oregon Manifest’s Bike Design Project. Along with the California-based design firm, organizers of the national competition asked teams from Chicago, Portland, Seattle and New York to create an urban bike that most represented their city. Teams included both a design firm and frame builder — the San Francisco team being composed of Huge Design, bicycle fabricator Forty One Thirty Cycle Works and engineering partner PCH Lime Lab.
