Hi ! As result of the previous post, I performed an upgrade of the Z Nut holders, the parts are stiff not any problem there. I was curious about the shape of the linear infill, so I cut the part and actually

Hi ! Just a short post about the print quality. When there are sharp angles you have vibrations that are generated given the weight of the moving parts, the quality of the chassis as a whole and other

Hi ! As said in the previous post, I am changing a lot of things on the Bed Supports due to bending issues. Before I just put 2 2040 profiles and link them with two 2020. It was not a good idea due to

Hi ! I saw this announcement yesterday, I found it very interesting, even if we are still lacking details or use cases. The MELD process is a 3D Metal Printing based on Friction welding, more specifically

Hi ! Long time I did not post anything on my custom 3D Printer. I still have a bunch of parts stuck somewhere in the world. Hopefully, I received recently improved belts made of PU and 6 steel wires. So

Hi ! Yesterday I was at the AddFab in Paris, France (not Texas :)). It is an exhibition of French 3D Printing Professionals: manufacturers, software, services around 3D Printing, prototyping and so. It

Hi ! I saw this Prusa Filament Changer and I think it is worth to have a look at. Previously, they used 4 extruders that was feeding a single hotend through a join coupler. They had issues especially with

Hi ! Just a short post about the thermal insulation of the HotEnd and the HeatBed. Why ? The thermal insulation reduces the energy wasted to heat the bed or the hotend. Your heatbed/hotend will heat faster

Hi ! Just a few things about the extrusion flow on FDM printers and the need for a tight control/measure of the speed, the temperature, and the "position" of the extruder to allow to detect missed

Hi ! I just want to share my enthusiasm when I see this kind of robots inspired by nature It seems there is something on the actuators, I found them small Links:

Hi ! Any FDM Printer has either a direct drive or a bowden extruder. There is a third way: the remote direct drive extruder. Quick Recall A direct drive extruder has its name implies pushes the filament

Hi ! Tool Change like the ones implemented in CNC is very appealing for 3D Printers. I want to implement one at some point on my big one. Why ? You can automatically change your print heads for different

Hi ! I found a previous publication of the paper I cited in It covers the effects on the nozzle diameter and the layer height on the part strength, it is a complement to the previous publication. Paper:

Hi ! I found this short paper discussing and showing few interesting things on the relation between PLA Temperature, the effect of a cooling fan, its print speed, its cooling and few other cases. Paper:

Hi ! This is a very short update on the previous AR2 6 Axis robot. The kickstarter is live. The robot is provided as a kit of aluminium parts for less than 1200 $. Given the amount of parts and the machining

Hi ! Bunnie wrote an interesting post on the IQ Motor. This is an integrated motor with position, allowing closed feedback loop. The main target is the drone market, but it will be quiet nice to have such

Hi ! A short post about a 6 Axis Robot that I follow since a while, his creator is going to launch a Kickstarter campaign. The first iterations were made with 3D Printers, the last one is implemented in

Hi! I had many issues with the hotends/extruders on my Makerbot clone. I received parts to perform maintenance but it never happens as planned :-). To keep it short, I managed to adapt the existing hotend

Hi ! I found 2 promising projects of such Pellet Extruders that are on the commercialization path. Recently I wrote a short post about the Kickstarter campaign of the Gigabot Pellet Printer, where the

Hi ! This post is about my Vintage AKAI AM-2250. It has failed sometime ago. My question is the following: is it worth to repair it or to hack it ? This amp is from the late 70's begin of 80's, it is a
