Q & A

  • What is the main purpose of the video?

    -The main purpose of the video is to share lesser-known slicer settings that can enhance the quality and efficiency of 3D printing.

  • Why might someone switch to OrcaSlicer from other slicers?

    -One might switch to OrcaSlicer for its user-friendly interface, advanced features, and the ability to monitor the printer directly within the slicer without needing a separate browser window.

  • What is the significance of the infill threshold setting in 3D printing?

    -The infill threshold setting allows the slicer to switch from sparse infill to solid infill based on the model's geometry, which can be crucial for adding strength to specific areas without increasing the overall model's perimeters.

  • How can modifier areas be used in 3D printing?

    -Modifier areas can be used to add shapes or objects to a model and then modify that area of the primary model accordingly, such as increasing perimeters, infill, or changing the infill type, to add strength or save material.

  • What is a negative volume modifier and how is it used?

    -A negative volume modifier is a feature that allows cutting out the difference between one shape and another within a model, which can be used to remove unwanted parts, deboss logos, or create holes without needing advanced CAD skills.

  • Why is the 'close holes' feature useful in 3D printing?

    -The 'close holes' feature is useful for automatically closing up the X-Y holes in a model, which can be helpful when holes are not needed, such as for mounting with a command strip instead of using screw holes.

  • What is X-Y hole compensation and how does it help in 3D printing?

    -X-Y hole compensation is a feature that widens holes by a specified amount before slicing, which helps to compensate for the printer's tendency to simplify line paths, especially for round objects, and prevent issues like too-tight holes.

  • What is the benefit of using combined infill in 3D printing?

    -Combined infill allows printing infill every two or three layers instead of every single one, which can save a significant amount of print time without affecting the aesthetics of the model, as the infill is not visible from the outside.

  • How can variable layer heights improve the 3D printing process?

    -Variable layer heights allow the slicer to automatically calculate the necessary layer heights based on the model's geometry, which can save time and material by using larger layer heights where high detail is not required and smaller ones where it is.

  • What is ironing in 3D printing and what are its pros and cons?

    -Ironing is a technique where the nozzle is dragged slowly over a completed layer to fill in gaps with a small amount of extruded filament. It can improve the surface quality of the top of the model but may take a long time and, if not properly set up, can worsen the surface by scraping material to the edges.

  • What does the 'cut feature' in slicers allow users to do and why is it useful?

    -The 'cut feature' allows users to cut a model at any angle and keep one or both of the resulting cuts. It is useful for modifying models more easily within the slicer compared to CAD programs, especially for tasks like creating custom angles or dividing models for easier assembly.

  • How can the 'complete individual objects' feature help in a multi-object print?

    -The 'complete individual objects' feature allows a slicer to print one object at a time before moving on to the next, which can be beneficial for quickly installing or using individual pieces of a project without waiting for the entire print to finish.

  • Why is modifying settings per object in a slicer beneficial?

    -Modifying settings per object allows for customization of print parameters for different objects within the same print job, which can save time and material by applying different settings like perimeters and infill percentages to different parts of a model as needed.

  • How does OrcaSlicer simplify the process of modifying settings per object?

    -OrcaSlicer simplifies the process by allowing users to right-click an object, select 'edit' in the parameter table, and view and modify all parameters for all objects in one quick view, making it more intuitive and less time-consuming.

The video discusses various lesser-known settings within different slicers like Cura, PrusaSlicer, Bambu Slicer, and OrcaSlicer, which can enhance the 3D printing experience.

💡Infill

Infill refers to the internal structure of a 3D printed object, which provides strength and stability. The video mentions settings that allow for a switch from sparse infill patterns to solid infill based on certain thresholds, which can be used to reinforce weak areas of a model without affecting the entire print.

💡Modifier Areas

Modifier areas are a feature in 3D slicing software that enable users to add or modify specific areas of a model. The script describes how they can be used to increase perimeters, infill, or even remove layers in certain areas to add strength or save material, showcasing the flexibility of the slicing process.

💡Negative Volume Modifier

A negative volume modifier is a tool within slicing software that allows for the subtraction of material from a model by defining the difference between two shapes. The video script uses it as an example to show how one can remove unwanted parts of a model or create debossed logos without needing advanced CAD skills.

💡Close Holes

The 'Close Holes' feature in slicing software automatically closes up the X-Y holes in a 3D model. The video explains how this can be useful for models that have holes not intended to be printed, such as those meant for screws, allowing for cleaner and more functional prints.

💡X-Y Hole Compensation

X-Y Hole Compensation is a setting that adjusts the size of holes in a 3D model to ensure they are not too tight due to the printer's simplification of line paths. The script mentions using this feature to avoid assembling issues with round objects, like the Bambu spool winder.

💡Combined Infill

Combined infill is a setting that allows the printer to print the infill of a model every two or three layers instead of every single layer. The video mentions this as a time-saving technique that doesn't significantly impact the aesthetics of the final print.

💡Variable Layer Heights

Variable layer heights is a feature that enables the slicer to calculate different layer heights based on the geometry of the model, optimizing for speed and quality. The script explains how this can save time by using larger layer heights where high detail is not required.

💡Ironing

Ironing in 3D printing is a technique where the nozzle is slowly dragged over a layer to smooth out the surface by extruding a small amount of filament. The video script describes it as a method to improve the top surface appearance of a model, although it may not produce a perfect finish.

Transcripts

play00:00

Knowing the ins and outs of your Slicer of choice can mean stronger

play00:04

3D prints, faster print times, less time spent in CAD customizing

play00:08

your models and much, much more.

play00:10

And in this video I'm going to share a handful of lesser known Slicer

play00:14

settings that will help you take your 3D prints to the next level.

play00:18

Let's dive in.

play00:26

Before we dive into the actual settings, just a quick note: To the

play00:29

best of my knowledge, all of these settings are available in Cura,

play00:34

PrusaSlicer, Bambu Slicer, and so on.

play00:37

But personally, I've made the switch over to OrcaSlicer, formally known as

play00:41

the SoftFever fork of Bambu Slicer, which itself is a fork of PrusaSlicer,

play00:46

which is a fork of Slick three up,

play00:48

whatever, you get the idea.

play00:50

Whatever Slicer you are using, you should be able to find these

play00:53

settings, though they may be named just a little bit differently.

play00:57

If you can't find them quickly, just remember that your

play00:59

Slicer has a search feature.

play01:02

I'm sorry, but this video would be way too long if I stopped to show how to navigate

play01:07

to each feature in every Slicer out there.

play01:10

Oh, and if you haven't tried out OrcaSlicer yet, you really should because

play01:14

as you're going to see in this video, it is really slick, no pun intended.

play01:18

And it's definitely worth checking out, especially if you want to

play01:21

be able to monitor your printer in your Slicer without needing to

play01:25

go to a separate browser window.

play01:27

Oh, and I know that some of you may already know about a few of

play01:31

these, so feel free to use the chapters below to jump around.

play01:35

Alright, let's get into the settings, shall we?

play01:38

First things first, let's start with one of the more practical ones and

play01:42

one that I use literally all the time.

play01:45

This feature allows you to determine at what threshold your Slicer will

play01:49

switch from sparse infill, like gyroid or grid, to solid infill.

play01:54

And this is great because on many models with smaller details or limbs,

play01:58

you may want those weaker areas to be completely filled in without having to

play02:02

up the perimeters on the entire model.

play02:05

I use this a lot on my own Bitcoin art statuettes, especially my Bitcoin

play02:10

bull, to make the narrowest parts of the legs and the thin tail sturdier.

play02:14

This has made it much easier to ship them around the world without damage.

play02:18

Speaking of wanting to make specific areas stronger, many of you probably

play02:23

already know about modifier areas, but basically they allow you to add

play02:27

any shape or even another object to your model, and then modify that area

play02:32

of the primary model accordingly.

play02:34

For example, you could increase perimeters only for that area,

play02:38

increase infill, remove top and bottom layers, do a different

play02:41

infill type, and much, much more.

play02:43

This is a great way to add strength, save material, add mouse ears for bed adhesion.

play02:49

There are so many ways that you can use this, and it's super valuable

play02:52

if you don't want to apply those changes to the entire model.

play02:56

While we're talking about modifiers, I do have to mention one that you

play03:00

probably know, but for those of you who are newer and don't, it's a must.

play03:05

In the same way that you can use modifiers to change settings in certain

play03:08

areas, you can also use negative volume modifiers to modify a model.

play03:14

Wow.

play03:14

Say that three times fast.

play03:16

Don't let the fancy terminology fool you though.

play03:18

A negative volume modifier is just a way to cut out the difference

play03:22

between one shape and another.

play03:24

This can be used to remove parts of a model that you don't want, deboss

play03:28

logos or symbols into your model, cut holes into something that doesn't

play03:32

have them, or tons of other uses.

play03:35

This is especially useful if you aren't yet very confident in CAD software.

play03:40

So that's adding holes, but what if you want to remove them?

play03:44

Not to worry because there's a Slicer feature for that - close holes, which

play03:49

is a dropdown option under slicing mode.

play03:52

This is the one that I actually discovered by accident, and I spent a

play03:56

long while trying to figure out why my holes weren't showing up after slicing.

play04:00

Basically it gets the Slicer to automatically close up

play04:03

the X-Y holes in your model.

play04:06

Now, you might wonder why you need that, but I found it to come in handy for a

play04:09

lot of models that may have, for example, screw holes, but which I prefer to

play04:14

mount with a command strip, for example.

play04:16

Instead of fixing the modeling CAD or having an ugly hole that you

play04:19

don't need, you can just click one dropdown and the holes are gone.

play04:23

Okay, we've added holes, removed them, but what about compensating for them?

play04:28

Allow me to explain.

play04:29

One of the challenges with 3D printing is that the printer will simplify line paths,

play04:34

especially for round objects, which can cause things like holes to be too tight.

play04:39

This was particularly problematic for me when I tried to assemble

play04:42

the popular Bambu spool winder that everyone's been printing.

play04:45

Fortunately, you don't need to resort to filing your holes, get your heads

play04:50

outta the gutter guys, or modifying the models in CAD because you can

play04:54

instead use X-Y hole compensation.

play04:57

What this does is basically widen your holes by the specified

play05:00

amount before slicing them.

play05:02

I've used this feature to add a little bit of extra tolerance in

play05:05

models, and it saves so much time, frustration, and broken print.

play05:10

Speaking of saving time and frustration, now is a great time to

play05:13

thank this video's sponsor - PCBWay.

play05:15

As I'm sure you know, PCBWay offers incredible prices on custom PCBs, plus

play05:20

fantastic sign-on bonuses, but did you know that they also do custom sheet

play05:25

metal fabrication, injection molding, CNC machining, metal 3D printing,

play05:30

and like half a dozen other things?

play05:32

So whatever project it is you are working on, if you are looking for

play05:35

a great fabrication service to help you add functionality or quality

play05:40

from one piece to a thousand, PCBWay helps you save money and time.

play05:44

Visit the link in the description below to support the channel, and

play05:47

thanks again to PCBWay for being this channel's longest standing sponsor.

play05:51

Okay, let's get back into the video.

play05:54

Speaking of saving time and effort, here's one that I would hope most of

play05:58

you already know, but which for some reason isn't enabled by default on any

play06:03

of the print profiles that I've seen.

play06:05

Combined infill allows you to only print infill every two or three

play06:09

layers instead of every single one.

play06:12

This will mean thicker layer lines for the infill, but since nobody sees

play06:16

the inside of your model, it means that you can save a ton of time on

play06:20

printing without sacrificing aesthetics, which is a great segue into...

play06:25

Here's one that I'm always surprised people don't use more.

play06:29

You may not realize it, but certain parts of your models simply don't need

play06:33

small layer heights to look great.

play06:35

Conversely, other parts such as spheres need incredibly tiny

play06:39

layer heights to look even decent.

play06:41

So why not save time here where it's not needed and invest that time where it is?

play06:46

That's where variable layer heights come into play.

play06:49

You simply specify the trade off that you want on a continuum between speed

play06:53

and quality, and the Slicer will auto calculate the necessary layer heights

play06:57

based on the geometry of your model.

play06:59

You may just find that major swaths of your model don't need anything more than

play07:04

0.2 millimeter, and that's time that you can save or better use elsewhere.

play07:09

One such elsewhere is with the use of ironing.

play07:12

Ironing is a practice whereby your nozzle is dragged over a completed

play07:16

layer extremely slowly against the grain of the previous pass.

play07:21

While this happens, a very small amount of filament is extruded

play07:24

to fill in the remaining gaps.

play07:27

I'll be honest, ironing doesn't lead to a picture perfect surface.

play07:31

It takes quite a long time, and if it's not dialed in, it can even

play07:35

make your surface look worse by scraping material off to the edges.

play07:39

So if you need a surface to look perfect, it is better to have that

play07:42

side face the build plate or sand it.

play07:44

However, if that's not an option and or you want the top of your model to

play07:48

look just as good as possible, then definitely check out ironing because

play07:52

it beats sanding your models by hand.

play07:55

Here's one that I've only recently begun using more: The cut feature.

play07:59

Many of you know that you can cut a model by syncing it into the build plate, but

play08:04

recent versions of PrusaSlicer and its derivatives also offer the ability to

play08:09

actually cut a model on any access at any angle with the option of keeping

play08:13

one or both of the resulting cuts.

play08:16

This is super useful and frankly, easier to do in the Slicer than even

play08:20

the easiest to use of CAD programs.

play08:22

In case you haven't noticed, I'm incredibly impatient and sometimes

play08:25

when I'm working on a project such as my honeycomb storage wall, link

play08:29

up here, I want to install the pieces as quickly as possible.

play08:34

Fortunately, I discovered complete individual objects, a feature

play08:37

which will print one object at a time before moving on to the next.

play08:41

In order to use this, you'll need a few things.

play08:44

First, you'll need models that are low enough to not cause collisions when the

play08:49

print head moves onto the next model.

play08:52

Second, you'll need your Slicer to know the actual clearance of

play08:55

the print head so that it can accurately predict any collisions.

play09:00

And third, you'll need to space out your models enough so that the

play09:04

collisions don't actually occur.

play09:06

Fortunately, all of this is either automatic for popular printers

play09:09

where the software already knows the print head size, or easy

play09:13

enough to configure in your Slicer.

play09:14

Just please do me a favor and pause the printer before you

play09:19

reach in to snap off the parts.

play09:21

While we're on the topic of printing things one by one, let's talk about

play09:24

configuring them one by one as well.

play09:27

What if, for example, you have a few different objects that you need to print,

play09:31

but you want to have five perimeters and 10% infill, and another one to

play09:36

have 50% infill in just one perimeter.

play09:39

You could of course, use modifier shapes, but that's slow.

play09:42

Instead, you can actually modify settings per object.

play09:45

Now, this used to be somewhat annoying and confusing in PrusaSlicer with a

play09:49

bunch of right clicking and modifiers added into the object view, that you

play09:54

then need to go down and click to see.

play09:56

But in OrcaSlicer, it's actually really cleverly done.

play10:00

Simply right click the object, hit edit in the parameter table, and you can see

play10:04

and modify all of your parameters for all of your objects in one quick view.

play10:09

Clever, right?

play10:10

So there you have it, 11 of my all-time favorite Slicer settings for getting

play10:15

more out of your 3D printer, saving time, strengthening prints, and so on.
