Canyon Prints 3D Bicycle Parts

Did you know that...

Canyon uses BigRep ONE large-format 3D Printers to iterate, optimise, and prototype new bicycle designs faster than ever. In this video you can see why Canyon chose to use a BigRep ONE.

Johannes Thumm, Senior Design Engineer at Canyon said; "We started a very exciting new project, where we wanted to rethink the way a mountain bikes needs to look."

He continued; "Thinking beyond the limits of traditional manufacturing and trying to see what's possible with new technologies like 3D printing." (more…)

The BigRep ONE 2022 New Features!

BigRep have revamped the BigRep ONE for 2022 following owner and partner feedback. Check out what's new below. We are particularly excited to see that there is an official full enclosure that will make printing of more advanced materials easier, stop the unexpected failures due to tripped interlocks and of course keep fingers out of the build area overnight. Read on to find out where the BigRep Team have taken this machine! (more…)

EMV-25VBB CNC Kit – The story

Over in the shop we are running a preorder for the CNC conversion kit. Here we would like to give you a bit of background on how it all came about and our design intent. From day 1 of ordering the EMV-25VBB milling machines, the CNC conversion kit was always going to be an option we would offer. As the development reaches commercialisation and release, let us give you a bit of background on how we designed and thought the project through. (more…)

Extruder mechanism upgraded: Bondtech Dual Drive

Since early July, we have a had a very successful working relationship with Bondtech, the Swedish company producing Dual Drive extruders. The Bondtech extruders without question have brought a step change in reliability of extrusion. Main characteristic of course is the driving mechanism used: Twin counter rotating hobbed wheels.

CAD mock up of R8 Spindle and QTC tooling

Drawbar tension for R8 and MT3 collets to work safely with QTC tooling?

We have been asked on a number of occasions, and seen in a number of forums, the question of "How much tension should I put on my drawbar when I use  Emvio (or Tormach) repeatable Z tooling?" This question is a very common for those looking to make a pneumatically actuated drawbar using Belville washers. So what do you need to know about Drawbar Tension? (more…)
Emvio Engineering Nema 17 stepper motor damper installed

Damping the sound of stepper motors on 3D printers

Most of us that tinker with 3D printing have wondered how to reduce the groan and squeal of the stepper motors driving us nuts. Especially when long prints are involved! For a while now we have been using and selling our own vibration dampers that place a rubber buffer between the stepper and the printers frame. The rubber is thin and stiff enough to maintain accuracy of the stepper motor while reducing the vibrations being transmitted to the body of the printer. (more…)
BCN3D Sigma 3D Printer

Exciting times, European 3D printer that kicks ass!

After looking around for a the hottest 3D printer to try, we have finally settled on a brand that will give the top players a run for their money.  So we would like to tease you all with the new kid on the block: BCN3D's Sigma   Pretty sleek. Serious engineering going on and a CE mark to boot. Where can you start?
  • Enclosed design with 210x297x210mm build volume
  • Dual heads independent that park when not in use
  • Profile linear rail, not round bar, on the axes!!!!!!!!!
  • TOUCH SCREEN!!!

3D printing obsolete machine parts

Being thrifty in the time of turmiol and economic difficulty is imperative to survive as a company. This has been the case with Oyzo manufacturers Giokarinis of Samos. Every summer we return to Samos for around two weeks to return to our roots and the directors of the company are close personal friends. It was over a glass of ouzo that we started discussing that their factory would have to reduce production in as they were having issues with sourcing spare parts. Bearing in mind that the machines are mature and well used, the original manufacturer had sold up and there are capital controls in place, it was almost impossible to source and import parts. We took on the challenge to design and manufacture some of the more critical wear parts: the bottle neck grippers (more…)

Quick change and repeatable Z tooling for MT3 and R8 spindles?

Industrial and hobby machinists alike all have the same pet hate when it comes to changing tools whether using a Bridgeport knee mill or a bench top CNC mill:

"It takes too long!"

Lets explore this topic and how Emvioeng.com will help small and large workshops alike become more efficient.

Web Browser based CAD? OnShape seems to think its OK

It is not often that the CAD industry gets shaken up as much as it has in the past 12 months. First we had Autodesk Fusion 360 coming out with a Cloud based service and we have recently received word of OnShape.

The pedigree of OnShape could not be purer, it is spearheaded by the founders of Solidworks, an industry favourite for as long as I can remember.
