Poly Lactic Acid (PLA) is a great 3D printing material for early stage prototyping on simple geometry parts, made out of biodegradable corn starch. Because this material is relatively cheap, you can cost effectively 3D print multiple iterations of an early stage part design.PLA could be CNC machined but it is typically not available in sheet stock or rod form.
|3D Printing||2-4 Days based on size||White & available in all major colors.||FDM - 150 µm|
SLA - 40 µm
|Lowest in market||Strength & complex geometries|
|Injection Molding||20-30 Days||White & available in all major colors.||As low as +/- 0.030 mm||Qty & Precision dependent||High strength, Good surface finish.|
|Services Name||Max Size||Min Size||Min Thickness||Undercuts||Radii Depth|
|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|
No, ABS is more durable than PLA.
PLA can be machinable but PLA is generally not available in blocks form.
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.
