Hello

Somebody remember the topic about 3d printers?

I think I saw some messages about this ...  Huh...  

I´m printing COX tee dee parts and assembly the plastic engine.

That is an accomplishment. 3d printers are not as easy to set up as most people imagine.

While uniform objects are relatively easy, once you get the printing speed, flow of the molten plastic, layer height, nozzle temperature and bed temperature set properly! This takes time and varies by material.

However, objects that have protrusions - like the venturi - are very difficult to set up to avoid the plastic sagging before it has hardened.

I am impressed with this.

But mostly trial and error! I use ABS plastic and this needs higher temperatures but I use it for structural parts (and it is fuel proof). I have the burns and blisters to prove it. (I can't resist touching things to see if they are hot!)

Modeling COX engines with 3D Printer Empty Video-run

Post  jmcalata Sat Feb 27, 2016 6:55 am

Ja, ja, ja ... curiosity killed the cat ... Ian you do not touch hot parts with the finger.  lol!

Here the video-run of COX Tee dee .15 with PLA material.



I still do not have hot bed and can not use ABS, only PLA.

Hot bed is optional for my ·D printer Hephestos called I-Phrusa 3 of Bq

Also clear plastic show piston movements into cylinder. lol!

It has created the cylinder with transparent PLA to see the movement of the piston within the cylinder . Jmcalata and soon finished the set where the case will also be translucent so you can see the crankshaft with the rod. Babe Bee .049
