The web is slowly beginning to understand the proportion of the 3D revolution, so it is populating itself with virtual warehouses of printable models. You can find a good overview of these virtual repositories in this post. Going to rummage through the databases we will realize quite easily that the projects are divided into 2 main categories, the ignored and the famous.
Among the most famous we find without any doubt the Benchy 3D model, one of the most printed models ever. But why all this success for this little boat? This boat is a real stress test for 3D printers, practically a concentrate of Monday morning in the office after a Sunday night of alcohol… is a summary of all the situations, more or less challenging, with which your printer sooner or later will have to deal.
What are you waiting for! In order to obtain comparable results, as in any self-respecting experiment, you have to start with parameters, if not equal, at least similar, and therefore first consider the factors to be taken into account for this print! You will undoubtedly need the STL model to be processed, you can find it at this address.
Once the printing is finished, the difficult part begins, learning to read between the lines what our printer wants to communicate to us through the result obtained. The different surfaces of the 3D Benchy model reveal typical problems regarding surface finish, model accuracy, deformation, and more…. If you have difficulty viewing the text you can refer to this easy guide — Cylindrical Shapes — The chimney is designed to define concentric cylindrical shapes with internal and external diameters.
These clearly show errors in roundness, this test, given the short time between layers can also signal lack of cooling or overheating — Overlap surfaces — Overlap problems are the plug of the side of the 3D print, you can notice them inside the hull.
If printed horizontally, the Benchy Bridge and roof will reveal the stepped level. If now you are not fully satisfied with the test and want to deepen it further you can move on to the measurement of all known parts in the small boat.
Comparison is a valuable tool, and it is even more important to compare the results between different 3D printers, assuming that similar printing settings are used. Below are the measurements of the various parts to allow you to compare to the tenth of a millimeter! The depth of the blind hole is The depth is 9. The depth of the flange against the hull is 0. Parallel inner surfaces are cut horizontally in the bridge.
Its outer diameter is The depth of the frame is 0. Most Viewed Posts. Post Views: Like this: Like Loading Leave a Reply Cancel reply.Benchy - Why so many problems?
Joined: Apr 23, Messages: Likes Received: Just a passing thought, but reading all the posts about printing the supplied benchy, the consensus seems to be that as supplied, it is almost impossible to print properly and there is a need to intervene to adjust the fans to avoid thermal runaway.
So perhaps I just don't understand the problem, but why wouldn't E3D produce a file that is printable with the BB? Seems like it is pretty pointless to keep giving people an unprintable file as a tool for testing their newly assembled printer Greg Holloway Administrator. Joined: Sep 4, Messages: Likes Received: It's usually because the print-cooling fan is not correctly positioned.
This means air is directed straight at the nozzle instead of below and away from it causing the nozzle to cool and trip thermal runaway protection.
The fix is to preposition the fan correctly. The hack is to unplug the fan or re-slice the benchy and reduce the fan speed so it makes the problem appear to go away. Seems like many people are doing it wrong then as I'm seeing a lot of advice to micro-manage the fan settings instead of re-positioning the fan.
Thanks for the input, I'll pay close attention to the fan position when I get my chance to build Joined: Oct 20, Messages: Likes Received: Finished my build's commissioning and configuration today, printed the supplied Benchy, absolutely zero issues with thermal runaway. Haven't touched the fan controls. I did, however, notice the side facing the fan is very saggy, unlike the side facing away from it, which would indicate my fan might be a bit lower than it probably should be.
I think. Alex Moderator. Joined: Sep 4, Messages: 2, Likes Received: The problem is to provide a file that will work for all the possibilities how you setup the box. This is no Ultimaker 2 where everything is "dialed in" because you have no real possibilites to adjust something. I myself had problems at first getting the homing and moving to the dock right. My head crashed in the back of the IR sensor hung at the ooze wiper.
The tolerances are quite low, only a few millimeters, and so is the fans positioning which is essential to get no thermal issues.When printing, unexpected challenges may arise that will need to be resolved in order to complete a successful print. Often times, the appropriate response to a printing issue is not immediately apparent.
This guide outlines some of the most common issues faced by 3D printing practitioners and highlights steps that may be taken to resolve those issues. This is comparable to a medical examination where the doctor inquires about the symptoms or behavior the patient is exhibiting or experiencing while being ill. Issue Details - This provides additional information on the issue from actions during printing or the results upon completion.
Cause and Suggested Solutions - This lists in order from highest to lowest probability the source or cause of the issue and suggested solutions to follow for issue resolution. Side profile of the printed part shows a bow near the bottom or next to the surface that was adjacent to the print bed.

My favorite thing in the world is sharing the hard work of a maker. Simplify3D announced that they are releasing their visual troubleshooting guide for 3D printing. Anyone who has had experience 3D printing will tell you that there is a common list of problems that nearly everyone experiences at some point.
This troubleshooting guide may help to considerably speed up the process of tuning your printer. While the solutions listed to these common problems do include specific settings for the Simplify3D slicing software, the company was nice enough to also explain the common reasons for these issues, allowing you to utilize this for whatever software you are currently using.
How to Solve the Most Common 3D Printing Problems
The large, well photographed pictures make it easy to understand exactly what they are referring to, a task that can be quite difficult when many of these issues sound very similar when describing them. Enthusiasts may also point out that there has been a somewhat visual troubleshooting guide available on the Reprap Project wiki for some time.
However, the one from the RepRap community is a bit of a mess to navigate and find your issue. I really like how Simplify3D has approached this, and have noticed a few tweaks I could probably make on my own machines! Latest Caleb Kraft. By Caleb Kraft Caleb Kraft. Related Stories from Make:.

There are plenty of useful tips to learn that can help improve your 3D printed results! The first layer does not stick to the bed and the print quickly fails. Printer does not extrude enough plastic, gaps between perimeters and infill.H 265 fpga
Lots of strings and hairs left behind when moving between different sections of the print. Extruder is clogged or jammed and will no longer extrude plastic from the nozzle tip.Should you 3D Print in ABS? Probably not.
Very thin, stringy infill that creates a weak interior and does not bond together well. Gaps between the outline of the part and the outer solid infill layers. The nozzle drags across the top of the print and creates a scar on the surface. Gaps in the corners of the print, where the top layer does not join to the outline of the next layer.
Side walls are not smooth, lines are visible on the side of the print. Gaps between thin walls of the print where the perimeters do not touch. Very small features are not printed or are missing from the software preview. Extrusion amount tends to vary and is not consistent enough to produce an accurate shape.
Warping of large parts, particularly with high temperature materials such as ABS. Poor surface quality on the underside of the part where it touches the support structures.
Dimensional issues where the measured dimensions do not match the original design intent. Sagging, drooping, or gaps between the extruded segments of your bridging regions.

Layer Shifting.So I have some experience with 3D printing, doing it at my school. But recently, I got a new Ender 3, and so I'm need to learn Ultimaker Cura, which I thought would be good to use for it. In adding some basic upgrades to the printer, I thought it would be a good idea to get some benchmark using 3D Benchy. On my first print of Benchy, I saw some salmon skin artifacts, as well as some random bumps on the sides of the Benchy, and some random lines on the deck.
On the result, most of the salmon skin was gone. However, the other problems still remained. Right is second Benchy print- after TL Smoothers are added. I'm pretty sure that I can fix the lines on the deck of Benchy by turning combing off.

Please, correct me if I'm wrong. However, I'm not really sure about the bumps on the side of Benchy though. I don't believe it's a problem with my filament because the bumps are consistent.
All bumps are in the same spots, on both prints. Maybe it has something to do with the extruder doing this circled below in BLACK in the Gcode attached if you want to look at itbecause the areas where the dots are seems to correlate with the places in the Gcode where the extruder does this. If this is not the problem, what is?
How do I fix this? It's found mostly in the layers just after layer What I think might be causing the problem is circled in black, though I'm not sure if it actually is the problem. The original Gcode is attached if you want to look at it. I thought someone might answer by now.
In general I get better quality if the speeds are all the same - every speedup or slowdown causes over or underextrusion and I get these bumps like this. Also printing slower is better as then the pressure is lower in the nozzle and less likely to splurt out like this.Bmw f30 turbo failure
However, I still got the same resulting bumps, which the only difference was that they were a tiny bit smaller.Frustrated with Fused Filament Fabrication? Read our 3D printer troubleshooting guide to the most common 3D printing problems and their solutions. Discover how and when these 3D printing problems occur, and the steps you can take to avoid them in future. This can also result in horizontal cracks in upper parts.
As the ABS or PLA filament cools it starts to contract very slightly; the problem of warping arises if the plastic is cooled too quickly. The first layer does not stick properly, and some parts come loose. There are unwanted lines at the bottom. If the nozzle is too close, blobs may be the result. Also important: the print bed has to be as clean as possible. Fingerprints on the plate can prevent the first layer from sticking to the plate. One of the rods in the Z axis is not perfectly straight.
The printer failed to provide the amount of plastic required for printing the skipped layers. This is called temporary under-extrusion. There may have been a problem with the filament e.
Friction has caused the bed to temporarily get stuck. The cause may be that the vertical rods are not perfectly aligned with the linear bearings. There is a problem with one of the Z axis rods or bearings. The rod could be distorted, dirty or had been oiled excessively.
There are cracks on the sides, especially on taller models. Because of this, adhesion in the upper layers is lower. When the print head moves over an open area otherwise known as travel movesome filament has dripped from the nozzle. Under-extrusion is when the printer cannot supply the material needed or as fast as needed. Under-extrusion results in thin layers, in layers with unwanted gaps, or in missing layers entirely see 3D Printing Problems 5: Missing Layers.
There are several possible causes.
First, the diameter of the filament used does not match the diameter set in the slicing software. Secondly, the amount of material that is extruded is too low because of faulty slicer software settings. Alternatively, the flow of the material through the extruder is restricted by dirt in the nozzle. We will continue to provide another 10 common issues concerning 3D printing.
