Cease believing these 5 myths about multicolor 3D printers before you purchase one

Multicolor and multi-material 3D printers aren’t new, however they’re fairly a current improvement if we’re speaking in regards to the globe of reasonably priced, shopper 3D printers.

With reasonably priced machines just like the Centauri Carbon 2 Combo rolling into city, I think fairly a couple of individuals are going to make the soar to a printer that may take a number of filaments directly. Even the unique Centauri Carbon has an inexpensive improve package that can flip it right into a four-filament printer within the span of a day.

But going from a single-filament printer to a machine that may deal with between 4 and sixteen rolls of the stuff for a single print is not only a change in amount. There are some actual misconceptions about how these printers work, and what it is wish to dwell with them.

Multicolor and multi-material printing are the identical factor

They each have “multi” within the title, at the least

If you are printing a mannequin with 4 totally different colours of PLA, then you definitely’re in all probability not going to have any points. If, nevertheless, you begin mixing PLA, ABS, TPU, or different more exotic filament types, you will rapidly notice that some issues had been simply not meant to combine.

When you determine what filaments to make use of in a design, you actually need to do your analysis, and keep in mind that even inside the parameters of a single filament sort, there’s infinite variation. Which means you will in all probability need to make some easy blended check prints with the precise filament you will have, and never waste a 50-hour print solely to understand considered one of your filaments has an additive that makes it shear off one other.

The ELEGOO Centauri Carbon 2 builds on the stable basis of its predecessor and provides an reasonably priced, efficient multicolor system to the combo.

If the filament suits, the multicolor system can use it

It’s not nearly caliber, guys

I ran afoul of this one personally fairly just lately. There’s a pleasant semi-transparent multicolor PLA that I’ve been utilizing with my common single-filament printer, with out issues. So I assumed I’d strive it in considered one of my multicolor methods, and now that machine is out of fee till I can discover the time to take the extruder aside and clear out all of the shattered little items of filament clogging the gears.

It seems this filament is okay being pulled on, and with a small quantity of minor retraction, however when the printer tries to do a filament change, which includes a protracted reversal again onto the roll, it simply snaps and shatters. So if you wish to use a filament, verify if it has been cleared for AMS use, as a result of the brittle or abrasive varieties may not like what occurs when filaments change.

“Purge waste” or “poops” as everybody likes to name them, are a serious level of competition with multicolor printers. Basically, each time you modify filaments, you must reduce and purge the filament nonetheless inside the recent finish. How typically this occurs all is dependent upon your particular design.

If you intend your coloration modifications fastidiously, you’ll be able to have a very minimal quantity of purge waste, however when you simply paint the mannequin to your style without any consideration for what number of filament modifications you will want, then you possibly can be tons of and even hundreds of purges.

All multicolor printers waste large quantities of filament

But it ain’t low-cost

This fantasy has solely just lately turn out to be a fantasy as a result of engineers have been engaged on the issue of purge waste for years at this level. There are a number of totally different options, however it appears essentially the most promising one proper now’s “instrument altering” printers. The entire cause you must purge is to clear the recent finish, however what when you had a devoted sizzling finish for every filament in your machine? All it has to do is swap sizzling ends with every filament change.

Well, it sounds straightforward, however these printers are mechanically advanced and nonetheless value fairly a bit of cash. However, you’ll be able to not assume that simply because a printer makes use of a number of filaments, it may have purge waste.

The purge tower is simply pointless waste

It’s not even the proper title

See that little tower behind these multicolor skeleton sharks I used to be printing? That’s what individuals typically name a “purge tower,” and you may see people on boards typically say that you do not really want it.

The factor is, it is really a “priming” tower, and its goal is to get your nozzle stress proper earlier than persevering with the print. It’s the identical factor a single-filament printer does in the beginning of the print, however clearly it solely has to do it as soon as. If you flip off the priming tower, you’ll be able to have under-extrusion and layer adhesion points. For most individuals, it is in all probability finest to go away it on. It actually would not use that a lot materials.

These printers are nonetheless a piece in progress

While fundamental filament-switching printers are reasonably priced and pretty dependable, 3D printing expertise has lots of room left to develop. There are some loopy applied sciences rising on the excessive finish, working to sort out the downsides and introduce new capabilities.

That’s earlier than we even contact on the globe of full-color resin printers, which nonetheless value as a lot as a (very good) automotive, however sooner or later that too might be a desktop machine.
