Design Essentials for CNC Machining

In this episode, we discuss essential design considerations for CNC machined parts. The topics we will be talking through today are:

  • 6 ways to cut machining costs
  • Turning to Lathe for cylindrical parts
  • Moving between 3D printing and machining for plastic parts
  • Jigs, fixtures, and capacity relief

Protolabs Q&A: LSR

In this episode we answer your questions on Liquid Silicone Rubber (LSR) with Richard Anthony, an Application Engineer at Protolabs and our Injection Moulding Champion for Europe. See below for a list of questions answered in this session:

  • What is LSR?
  • What industries is this application used for?
  • What are the similarities between LSR and standard Injection Moulding?
  • What is the maximum part size for LSR?
  • What kind of finish can I expect from a LSR part?
  • Would I need to consider draft?
  • Should I anticipate sink with LSR?
  • Is the part ejected using pins?
  • Can I produce parts with undercuts and is there anything I need to consider here?
  • What types of LSR do Protolabs offer?
  • In optical LSR, is there any discolouration?
  • Can you mould parts in different colours?
  • Why am I not able to supply you with a different grade of silicone to mould my parts in?

Family Tooling and Multi Cavity Moulds

In this episode, we talk you through some important injection moulding extras that may support your projects: family tooling and multi-cavity moulds.


Protolabs Q&A: CNC Optimisation

In this episode we answer your questions on CNC optimisation with David Ewing, EMEA Product Manager – CNC Machining at Protolabs. See below for a list of questions answered in this session:

  • What is CNC Machining and why is it important?
  • What are the advantages of using this process rather than others?
  • What advice would you give on hole depth and diameter?
  • My current design is quite complex – what tolerances can I achieve with you?
  • There’s a threaded element to my part design, do you have any guidelines on maximum size I should go for?
  • I’ve heard about ‘burring’ but can you explain what this is?
  • What restrictions do I have with CNC machining?
