The MatterHackers 3D Printing FAQ

We get requested numerous questions on 3D printing, and rightfully so; it’s an advanced world! After spending numerous hours answering telephone calls and emails, we realized we must always most likely have a useful resource for some fundamental info, to assist these new to the wonderful 3D printing universe. So with out additional ado, welcome to the…

You have some questions, we have some answers.

You’ve got some questions, we now have some solutions.

1. How a lot stuff can I print with one roll of filament?

A: So as to reply this, we have to think about just a few issues. I’m gonna throw out some jargon, however don’t fear, I’ll clarify all of it in a minute.

• We have to know the scale of the article
• We have to know the share of infill
• We have to know whether or not or not the half requires help materials

For starters, we all know that every roll of filament is 1 kg, or round 2.2 lbs of fabric. So with a purpose to decide how a lot we are able to get out of this, we’d like a pattern half. We’ll start with one thing easy, like a chess piece. We’ll use a pawn for this instance.

So the very first thing that I do after I wish to decide the load of an element, is open up the software program MatterControl. (It’s a printer management software program out there totally free on our web site.) Then I drag the file for the half I want to take a look at, and drop it in the principle window. From there:

1. I click on “Superior Controls”
2. I click on Slice Settings
3. I’m going to the “infill” menu possibility
4. I set the worth to “.5”

Be aware that you would be able to set the worth wherever between 0 and 1. Infill is the plastic contained in the half that gives inside help. You’ve got the choice of creating it utterly hole, or making it utterly stable. For testing functions, we’re going to place it at a hefty 50 %.

Follow the arrows!

Observe the arrows!

Now:

1. Save your adjustments
2. Click on on the preview window for the half you may have chosen.
3. Change from 3D view to layer view
4. Press generate.

The window will now slice the half. As soon as it finishes, it offers you details about how a lot it weighs, how a lot plastic will probably be extruded, and a tough estimate of how lengthy it’ll take. As soon as you already know the load of your half, you may decide how a lot materials will probably be used. Merely divide the full weight of the filament roll, by the load of the half you want to create, and you’ve got an in depth estimate of what number of you can also make. Within the case of this small chess piece, at a 50 % infill, the quantity is 121.3.

Wow, that’s numerous chess items!

Aww, nobody told me I had to do math!

Aww, no one advised me I needed to do math!

If you wish to make one thing larger in fact, the method is strictly the identical. That’s except you print one thing requiring…

SUPPORT MATERIAL

Assist materials is just like infill besides it used on the surface of an object. Usually it’s used when an object has an overhang or bridge. Scorching plastic doesn’t droop itself within the air very properly, so on giant or sophisticated elements, it could be smart to allow help materials. Assist materials is a little bit of sport changer although, as a result of it does require additional filament. Simply remember to take discover of whether or not or not help materials is enabled earlier than you identify the full weight.

2. How lengthy will my print take to complete?

A: I briefly talked about above how when slicing an object to seek out out it’s properties, additionally, you will see a time estimate. Whereas that is pretty self explanatory, there are just a few layers to this that we must always think about. With out slicing the article, you may get a fundamental sense of how lengthy a print will take by understanding some key slicing choices. These are:

1. Layer Top
2. Infill
3. Print Velocity
4. Assist Materials

1. Layer Top is a reasonably easy idea. It’s precisely the peak of every extruded layer. That is the largest issue when figuring out the print velocity, as a result of quantity of layers adjustments drastically, relying on the enter worth to your layer peak. You could find this within the slice settings as soon as once more. It must be famous that you just can’t enter a layer peak that’s bigger than the scale of your nozzle, and nonetheless have the layers join. Typically talking, a layer peak of .2 mm will take half the print time of a print with a layer peak of .1 mm. In case your nozzle head is .5 mm, you may have many choices for the standard, and the velocity of your print.

2. We already coated the fundamentals of infill, nevertheless it’s good to recollect: when you improve the infill, the quantity of plastic used goes up, and so does the print time.

3. Print Velocity is a extra in-depth perform of our software program, and most printers include default settings which might be suited to their use. Nevertheless, when you actually wish to get your elements performed quick, that is the place to go.

4. Once more, we briefly touched on the fundamentals of help materials, however relying on the mannequin, it could add a major quantity of plastic to the print.

3. Why gained’t the plastic extrude correctly?

A: 3D printing is hard beast, and there are numerous potential the reason why your extruder is having issues. The very first thing to do, is to just remember to know what materials you’re utilizing, and that you’ve the right temperature settings.

Every materials has an excellent vary of temperatures*, so we’ll go over every in flip.

PLA: 190-210°C**
ABS: 220 -240°C
NYLON: 240C-250°C
LAYWOOD: 175-250°C
LAYBRICK: 165-210°C
SOFT PLA/BENDLAY: 220-235°C
GLOW IN THE DARK PLA: 185-205°C
PVA: 170-190°C

*These temperatures are suitable with most printers, however you need to at all times examine with both your producer or different 3Ders to ensure your printer follows the identical tips.
**Be aware for MakerBot Replicator 2 customers: The Replicator appears to run a bit cooler than different printers, so though it could appear that it’s working on the incorrect temperature, know that the default settings are most of the time right.

If you happen to’re having hassle with any specific filament. I like to recommend beginning on the highest really helpful temperature, and with every try, scaling your temperature again 5 levels till you attain the optimum temperature to your surroundings. It is also necessary to ensure that your filament is being fed into the extruder correctly. If there’s an excessive amount of stress, the filament can get floor out, or worse, break.

If you happen to strive a spread of temperatures to no avail, and also you’re certain that your filament is being fed with minimal stress, you might have a jammed extruder.

4. I believe I could have a jam, what do I do subsequent?

A: Alright, so you observed your printer has jammed. Don’t panic! There are various issues that may be performed. We’ve got a way more in-depth article, that might be able to provide help to additional, out there right here. It must be famous that jams might be very difficult, so it by no means hurts to get as a lot info as doable. Nevertheless, when you simply desire a fundamental rundown, I’ll strive that can assist you out right here.

The 2 commonest sort of jams are as follows:

• The print nozzle being too near the mattress, subsequently not permitting the filament to be launched*
• Leaving the warmth on whereas the filament sits unattended for an prolonged time period.

*This could typically be solved with a easy leveling of the mattress. Both with the {hardware} on the printer or by the automated mattress calibration characteristic in MatterControl.

There are two very fundamental strategies to unclogging your hotend.

1. Warmth your printer as much as a barely greater than regular temperature, and try to push the filament by. As an example, in case you have a PLA jam, we advocate heating to 220°C(245°C for ABS). That is a lot greater than is important for regular prints, however not excessive sufficient to be harmful.

2. Warmth your printer as much as the usual temperature and push the filament a part of the way in which by. Then, permit the filament to chill to about 80°C (135°C for ABS). After it will get to that temperature, slowly retract the filament till the drive block is evident. In the most effective case state of affairs, you’ll pull up something that the filament bonded with whereas scorching, thereby cleansing the hotend and drive block. I might advocate that you just do that on occasion anyway, as a result of buildup within the extruder can sometimes trigger jams.

5. How ought to I retailer my filament?

A: At this level in your 3D printing profession, you might have come to know that filament is one thing that must be taken care of, to a sure extent. You see, most kinds of filament soak up moisture from the air, which might make it brittle or degrade. Within the case of one thing like nylon, it will possibly produce bubbles within the print. Let’s cowl the fundamentals for every sort of filament.

PLA/ABS: After we ship these supplies, we now have them sealed in a bag with a packet of dessicant. Whenever you recieve the bundle, it is high quality to depart them within the luggage earlier than you utilize them. When you open the bundle, it’s completely acceptable to place the filament with dessicant in a big zipper storage bag, or one thing comparable.

LAYWOOD/LAYBRICK: The packaging for this filament exposes this filament to the open air, so that you need not fear about something out of the atypical. Preserving it someplace dry ought to suffice.

SOFT PLA/BENDLAY: Just like the earlier filament, these supplies don’t should be saved any method specifically. Simply holding them from getting instantly moist must be greater than sufficient.

NYLON: Nylon however, is EXTREMELY succeptable to absorbing moisture. Even in a reasonably dry envirionment, it will possibly soak up the greater than sufficient to disrupt a print in as little as 24 hours. Fortuitously, this filament may also be dried out. For that reason, it isn’t solely essential to retailer your filament in a sealed bag with dessicant, however earlier than printing, some clients have discovered it helpful to dry it within the oven at low temperatures (200°F) for an hour or two.

GLOW IN THE DARK PLA: One other filament that should be stored in a sealed bag. This among the many barely extra absorbant filaments, so deal with with care.

PVA: Whenever you buy this filament, it’ll are available a sealed bag with a dessicant packet, typically two. This can be a water soluble filament, so holding it dry is completely mandatory. If it will get moist, it’ll in a short time turn into unusable. I like to recommend holding it within the unique packaging so long as doable. If it’s worthwhile to put it in a zipper bag, think about doubling down on dessicant.

Usually when you comply with these tips, you should not have an issue. There are occasional exceptions, as not all environments are the identical. It must also be famous that frequent temperature fluctuations appear to extend the possibility of creating a filament flip brittle.

6. Why gained’t my prints keep on with the mattress?

A: That is depending on two components: Printing materials, and print situations.

What we’ll do right here is break down every materials, and the optimum print situations for every one. (These are all assuming the mattress is correctly degree, which is VERY necessary.)
