Review SainSmart filament Pro-3 Series PLA et PETG

This post is also available in: Français (French)

SainSmart is an American brand that sells electronic equipment (Arduino, Raspberry, 3D printer and 3D filaments). I had heard about the quality of their TPU filament sold on Amazon, but today I will be testing a new range of PLA and PETG filament, the PRO-3 range.

This series is not yet sold on Amazon, but you can already find it on their website.

Sold in 1kg rolls on transparent graduated rolls to better visualize the amount of filament remaining, I will present the SainSmart PLA Pro3 in white, as well as the purple PETG. When unpacking the reels are very well packed with a small damp-proof bag. They fixed the packaging.

SainSmart PLA PRO-3 Filament Test

This white color is really very beautiful, a “very white” white and at first sight it looks good (not brittle). The recommended printing temperature for this PLA is very wide, from 185°C up to 215°C, the heating plate is optional, but recommended for large prints (between 40 and 60°C).

To get started, I will simply print a 3D Benchy on my Creality CR-10, with a printing temperature of 205°C, and heating plate at 60°C for a speed of 50mm/sec with a layer height of 0.10mm.

The result is impeccable, the colour remains faithful to the reel, the printed part is also very resistant (10% filling).

For my second impression, my son asked me for a baby groot which he wants to paint himself, this white filament is thus the ideal occasion to then be able to customize the printed part! I keep the same printing parameters, except the layer height which I change to 0.15mm.

Also very clean result! This white is really pure!

Before trying a print on another printer without heating tray, I also make a stormtrooper in low-poly, my son having broken the one I had last time with another brand, the advantage of 3D printing, when it breaks just reprint 🙂

Same layer height in 0.15mm, at 205°C/60°C, nickel !

And ultimate test, prints without heating plate on the Neva Magis from Dagoma, with an extrusion temperature of 210°C. I made several impressions of animals “flex articulated”, also to remain the resistance. No unstuck problems during printing despite the absence of a heating plate, great!

In first conclusion for this PLA filament, I am rather satisfied with the result, very easy to print, no bad smell and a very good resistance, only small downside, this coil is in theory perfectly wound according to the product sheet of the manufacturer, without knot. But I could notice 2 times on the spool 2 layers of filaments which overlapped, with a light tension with the unwinding, that did not block my impressions and I used for the moment approximately 200g of the spool, I just hope not to fall on other more important nodes, still 800g to be on it 😉

SainSmart PETG PRO-3 filament test

When unpacking, no surprise, we find the same type of transparent graduated coil for the PETG SainSmart Pro 3.

The recommended extrusion temperature for this filament is between 220°C and 250°C, a heating plate is also theoretically necessary, in “theory” because on the manufacturer’s site it is indicated to use a heating plate between 0 and 50°C, but generally the use of a heating plate is essential for PETG. I may test occasionally without a heating plate, but for this test I will start at a temperature of 70°C.

For this filament, I will use my Anycubic i3 mega, with a temperature of 230°C for the nozzle, and 70°C for the heating plate, I also increase my shrinkage to avoid the phenomenon of “stringing”.

I’m in no hurry, and I want to get the best possible finish, so I’ll start on a layer height of 0.10mm.

The result is impeccable, one can very slightly see through the wall the filling, it is normal this filament being translucent, the surface is really very beautiful and brilliant, for a first impression it is rather not bad.

Let’s go for a second impression, and for translucent filament nothing like a vase impression in “vase” mode (precisely). I keep the temperature at 230°C/70°C but to save some time I change the layer height to 0.15mm.

The result also very satisfying, no apparent defect, no hole, I also did a test by putting water in this vase, and no apparent leak. Even if there is only one wall, it is rather rigid. This shiny finish is really great, my wife loved this pretty little vase.

I took the opportunity to print another vase model

The rendering is really nice, we don’t see too many layers of printing, and yet I printed this vase in 0.20mm (2 hour printing). Unlike the PLA coil, I did not notice a “knot” in this coil, rather reassuring 😉

In conclusion, these PRO-3 filaments from SainSmart are really very simple to print, be it PLA or PETG. We have quality filaments here that I will not hesitate to buy, hoping to find these filaments on Amazon France in the future.
