    For the USA, I can recommend Matterhackers for good stuff. Their build series PLA is the lowest price and the quality is quite high. I've not had to call, but probably can, as they list a number in...

    The items you construct aren't going to be 1.75 mm or 2.85 mm thick and will have strength from the design, the layer adhesion and other factors. Things will break and if left in sunlight or exposed...

    I've found that my filament behaves in a similar manner, as if there is a contaminant entering from the filament end. It seems to be necessary to do as you have done, snap off pieces until the...

    @TayZc1, I found an amazon item that presents the dimensions: https://www.amazon.com/Pack-60ml-Syringe-Disposable-Hydroponics/dp/B07H3MH52R If you can confirm that these values match the item you...

    @SonofRojBlake, It's good to see your progress on this project. I suspect that unless the overall atmosphere of the posts from Christopher changes appreciably, he's just building up a post count that...

    A quick search for Velleman K8200 modifications present result with no indication of anyone converting the kinematics of the printer in the manner you describe. You would have to create a completely...

    If you can make a sheet of glass work for you, that's a good option. Aim for getting borosilicate glass, as it's more tolerant of the temperature changes. Another option would be to replace the bed...

    Could the printer be a Tronxy P802M rather than the one you've noted? I searched for the printer name and the results were null.

    80 mm / sec is moving right along. A couple of things to try would be to slow by 10-15 mm / sec and/or increase the temperature by 5-10 °C. This does not address the inconsistency of the defect, but...

    The small size of the holes would require a resin printer, rather than a filament printer.

    Your english is doing just fine.

    The process I used is adaptable to any shape and is called boolean subtract. One creates the primary shape, then the secondary shape (cylinders in an array) is...

    This was more a representative sample than a final model, as until now there were no specifications. Does the model resemble your objective, if one ignores the dimensional aspects? That is, the top...

    In the example of a flower pot shape, I envision a truncated cone. This would put a number of vertical cylinders either slicing through the perimeter of the cone or it would create a volume in which...

    It's difficult to picture the type of part with which you begin. Is it primarily a flat structure, similar to a grate used to keep debris from passing? Is it a blocky structure, similar to those...

    Most slicers have a selection of infill patterns from which to choose. My slicer defaults to a simple rectangular grid, which is vertically coherent and would certainly provide for straight-line...

    If the surface of the STL is manifold (has no gaps or discontinuities), you can use Meshmixer to remove the internal flaws. There are two methods. One is to use the Make Solid feature, but if the...

    If you have other filament with which to try, that would be another point of information. 60 mm per second is a pretty good speed, but what happens if you drop it to 40 mm per second? It appears in...

    The inconsistency would mean the moisture idea isn't valid. It's really difficult to tell from the photo and the limitations of the information available.

    At first glance, that looks like overextrusion, but your comment about unused filament makes me wonder if you have moisture in your filament.

    If you have a food dehydrator, run the spool in that...

    An inexpensive food dehydrator is one of the better ways to clear a spool of excess moisture. I've seen references of duration from four hours (seems too short) to seventeen hours. I've forgotten a...

    A popping sound would indicate excessive moisture content in the filament. A clicking sound can come from the extruder motor, indicating a clog in the filament path.

    Soft PLA is a product, but I don't think it would hold up well to the heat. There are TPU filaments which are flexible and quite strong. The rigidity of the part depends on the design and the number...
