I want to print a model of an animal cell.
What I have so far: I managed to use different colors to print out the different parts of the cell.
My question is: what is the best way to connect plastic 3d printed parts?
Glue? Melted plastic? I need it to have a strong connection and not very visible when used well, and preferable dries fast.
For ABS print, I recommend acetone. It is not a glue, but it will dissolve the plastic a bit and if you apply it to both connecting parts and push them together, they will stay connected after the acetone dries. However, it does not dry very fast and you have to be careful not to destroy the object.
For PLA I usually use regular super glue (Cyanoacrylate).
After doing the processes that hroncok described, the edges of the print can be finished with a 3D printing pen. The pen extrudes filament as a regular print head does, but is hand held. The filament can be extruded on the previous gap between the two prints. It will melt between the two sides and can be finished to create a smooth connection point.
For ABS I use a gel super glue (Loctite is my current favorite), it seems to slightly melt the ABS parts together and makes for a great bond. A slurry of old scrap ABS and acetone also works well, though I find that it will evaporate even if left in a closed mason jar over time. The small nozzle applicator and the fact it doesn't seem to evaporate makes super glue the better choice for me.
The gel super glue works "OK" for PLA but I've had parts fail after taking a small tumble. I just started using this acrylic cement for PLA. It cures very fast but seems to slightly melt the PLA in the same way the ABS options do.
For internal seams I like to put a bead of "high performance" hot glue over the seam. It's just a bit flexible and seems to do a good job taking drops.
Lastly I really like (but haven't mastered) friction welding parts together using a Dremel. Matt Griffin at MAKE Magazine did a great write up on the technique here.
it together easily. I've generally heard mixed reviews about different printer sets and I don't have the budget to get one of the higher end models. Found this little number on Amazon : [REPRAPGURU] DIY RepRap Prusa I3 3D Printer Kit With Molded Plastic Parts USA Company https://www.amazon.com/dp/B01E06IHJ0/ref=cm_sw_r_cp_tai_PgmYxb6DMARET Given the pieces of requirements, do you see this working...I'm new to the 3D printing world, but I've been doing some research over the past couple weeks. I need a printer that is decent enough to make prototypes using simple 3D software (I use Blender
I frequently have to print a range of different parts each with different geometrical features. So far, I generate each part's optimum printing parameters manually. To be able to print such parts more efficiently, I am planning to create a "library" of individual geometries, each with its unique set of optimum printing parameters. The issue I am facing here is in combining all the different... the joints between each different STL mechanically weak that can be snapped by hand. I wonder why such meshing is not possible. I realise that if each solid on the plater is assigned different printing
I've heard of 3D printed ears, limbs, and muscles. I assume if you were to attach one of these ears to a person, it wouldn't have a sense of touch and other properties that a real ear would have. So which properties of real human parts does 3D printing allow and which properties is 3D printing not capable of reproducing using current technology. And how do you predict those technologies will change in the future to further improve 3D printing? Also can someone explain how human cells can be printed? Would this involve some kind of cell-plastic filament? How would the cells survive, etc
I'm trying to find the correct way to read and understand the dimensions of a 3D printer. For example, if I read the following dimensions for the Robo 3D R1 Plus as 10x9x8 Inch - I want to know what 10 stands for (does it mean print height?), 9 (depth?), and 8 (width?); etc. I'm not sure if I'm assuming correctly. I know this should be simple, but I'm not sure where to reference the proper... to the height. Would this be the universal/standard way of referring to build specifications for all 3D printers?
I am following this video series to add auto-leveling to my Prusa i3. https://youtu.be/awsI9bMndJA I have printed the parts I need and have the servo and ss-5 endstop in my cart at Amazon. What I need to know is what wiring I need to connect the endstop to the RAMPs board? I bought this printer as a kit and all parts were included so I am learning slowly. The switch http://www.amazon.com/gp/product/B00HPLBAYW?psc=1&redirect=true&ref_=ox_sc_act_title_3&smid=AZHZ102UTKBMA Thanks!
I'm considering buying this package, the Kossel, as my first 3D printer. It's not the cheapest model, but apparently a high resolution and stable, which is what I'm after. The question is, what is the life expectancy of this printer, given the component list? Assuming the printer is constructed properly and properly taken care of, but used once or twice a week for several hours. Is it possible to make an estimate of how many years this particular printer could be used before it starts showing signs of wear? Parts list: 1x Complete set of platics for Kossel Mini (PLA) 1x Kossel mini
have. What I am looking for: a hotend mount plate that tightly fixes the hotend while having some holes for screws to mount it to the horizontally moving x-y drives. As I cannot print yet, it needs... be able to put any screws through it along the flat axis. also I would have to glue the layer with a 16mm hole on top. Not to say that I don't own a drillbit of 16mm diameter... Are there some completely different ideas around which I didn't think of yet? Additional info: the x-y axes are made from a scanner bed and an underneath mounted dvd drive laser positioner. Ideally, I'd want to mount
for different types of plastic due to shrinkage, and print settings (% infill, in particular) would be important to have thought about and evaluated to some extent, but I'm not sure about what else I might be missing. So my question is to anyone who has designed anything to be modularly printed. Have you really had to think carefully about the engineering side of the print? Or am I simply...For a while now, I have been thinking about designing things such as small bedside tables, game/dvd/bluray racks for 3d printing. I've always thought that making them modular would be a good way
So, have a plastic car part I want to duplicate because the driver side part is broken (I have the passenger side part) and It isn't sold anymore. It's a small piece that would be an excellent candidate for a 3D printed replacement. I know there are companies I can send a 3D model to that will happily print it for me, but I also need to create a 3D model from the part. Is there a company or service that I could mail the part to that would return it along with a 3D model of it?
