Did not work with my 3D print pen

Excelente producto. Muchas gracias.

So I will start with this, might be coming back to this review at a later time, unpacked my 3D pen for the first time since the move and after charging it, it popped hissed and died so ^^; not working ATM but I do have a 3D printer so will be looking over the material data of the filament to fill in the gaps in the info for others as well as doing a basic 3D print with a few colors at random, data gathered from 6 of the filaments (1/6th of the box) I started with weight as that gives a lot of info, PLA should be about 1g per foot (metric is mainly used in 3D printing so will be using it for the review) three were 9.5g a reasonable weight, one was 9.7g closer, but the other two 9.3g and the last one was 8.9g to make sure that the changes were not in fact from the coloring I took the lightest one and the heaviest one and strong them out, side by side the heaviest one was 49.7mm longer (a little over 2 inch’s) so there is some play in the overall length, next is the diameter its listed as 1.75mm but should have a +/- amount measuring four times per filament strand I came up with the +/- 0.06mm the high being 1.81mm and the low being at 1.69mm both on the same stand but my 3D printer could still print with it even though its listed as having a max difference of +/- 0.5mm so over all it works in a 3D printer, it should work in a 3D pen but can’t test that right now colors are good, printing temps a little high for PLA, it did not flow fully till 210C (I print most PLAs at 200C) not sure if its do to being 3D pen filament first time putting 3D pen filament into a 3D printer everything in the photos was printed with the same settings, however the gray and the black parts are from my 3D printer filament (only colors I have at this time) last bit of info the mini filament cores (printed with these filaments) is about 2g of filament or a little over 1/5 of the stand the cylinder is 7g and is almost max of what can be used with my 3D printer without splicing two strands together

Should probably deduct 2 stars, however the selection is truly amazing for PLA filament. The down side, as other reviewers have so adequately pointed out, is in the lack of proper packaging. What were they thinking? As a result, unless you live in a 10% humidity environment, you will need to dehydrate these before using them unless you want to put up with bubbles and pops as the filament extrudes from your pencil. If you have a dehydrator, I would caution setting the heat above 140°f for 1 hour or so. You are simply dehydrating, not trying to melt them or warp the coiled up filament. Store what you dehydrate in a well-sealed zip style bag with some silica gel packs to keep them dry. If you don't have a dehydrator, use a freezer bag and place some silica gel packs in with the fulament you want to use 1 week before). It won't completely dry it but should help. Yes, gel packs are not the best but they do help. I hope the manufacturer/seller begins to seal these before shipment. It's a simple fix to an otherwise really nice selection of filament.
