3D PRINTING (PART 15)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 First serious failure…After exactly 4 years of regular use, I experienced the first failure which is due to an aged component. Although Peek is a very strong material, it did not sustain any longer the thermal strength which it endured for years. This critical part is responsible for guiding the “cold” […]

3D prints: Stevenson screen

Building a basic weather station today is simple and cheap thanks to specialized integrated circuits featuring temperature, humidity and pressure sensing. Up to now my favorite is the Bosh bme280; you may easily find it ready for use on small PCBs, easy to connect on any prototyping platform. Adafruit industries is selling a very convenient […]

3D Printing (Part 14)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 The heating plate is made of two symmetric printed conductive layers ~1.5 Ohm each. As printed on the heating plate you may wire them for use with 12 V or 24 V power supplies. As we need to add an extra power supply the choice for a 24 V power supply […]

3D Printing (Part 13)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 Many PLA rolls were fused in my Welleman k8400. So far, it has been a good servant in spite of few breakdowns, mainly due to clogged nozzle or improper adjustments. Careful cleaning and fine tuning solved all  these problems except one which is my fault. As I was taking apart the […]

3D Printing (Part 12)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 3D printing can be tiring for the nerves… For a week or so, I was enable to print full size parts without enduring severe problems such as splitting layers, irregular faces and even gaps. Here is an illustration of the prints before the fix (on top) and after the fix. The […]

3D Printing (Part 11)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 3D printing is awesome. I am even wondering how I could live without it. I mean, in my professional, domestic and makers life. Before 3D print, I would have used wood, metallic wires, sheets of PVC or even cardboard to build parts in the quick and dirty mode. Just before 3D printing, […]

3D Printing (Part 10)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 Almost shocking ! As I was not very satisfied with the quality of my prints, and after experiencing a strange awful printing incident (Wires every where, big melted material blob on top), I started having some sort of concern about temperature readings. I used a very thin thermocouple connected to a pro […]

3D Printing (Part 9)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 Open source printers are for ? … They are for mods, hacks and tweaks ! The first obvious modification (not to say immodestly improvement) deals with the cooling air blower in front of the print head. Most the air flow would splits on the Y axis rod, some would re-converge thanks […]

3D Printing (Part 7)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 After many hours of parts design and many rolls of ABS fused in our Makerbot Replicator 2x, it is time to write a little review on this nice printer, just be before it comes obsolete because of the new announced Makerbot products. The Replicator 2x is doing what it was supposed […]

3D Printing (Part 6)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 I can still hear my father saying “The right worker is the one who owns the right tools”. Time, experience and my own thoughts lead me to slightly change this declaration into “The right worker is the one who is capable of making his fit for purpose tools”. This sentence not […]
