Big news for 3D-printing fans in the Philippines: SUNLU filament has landed at Circuit.Rocks, and the brand now has its own home on the shop. If you’ve been hunting for reliable, well-priced spools that play nicely with the FDM printer on your bench, this is the lineup worth knowing about.
SUNLU has built a reputation among hobbyists for spools that feed cleanly, lay down even layers, and don’t fight back when you switch projects. The new SUNLU collection page on Circuit.Rocks puts the brand’s most-used filaments side by side so you can grab the right material without digging through the whole 3D-printing aisle.
What’s in the SUNLU lineup right now
Three workhorse spools are in stock today, each on a 1kg reel at the standard 1.75mm diameter:
- SUNLU PLA 1.75mm 1kg — ₱735. The everyday classic. Easy to print, low warp, and friendly to first-timers, school projects, and quick prototypes.
- SUNLU PLA+ 2.0 1.75mm 1kg — ₱745. The upgraded PLA recipe — tougher than standard PLA, with better impact resistance for functional parts, brackets, and jigs that need to take a knock or two.
- SUNLU PETG 1.75mm 1kg — ₱757. Step up to PETG when you need temperature tolerance, layer adhesion, and a bit of flex. Great for enclosures, outdoor-ish parts, and anything that needs to survive a hot car or a tight fit.
Who’s it for?
If you’re running a Creality Ender, an Elegoo Neptune, a Bambu A1, or pretty much any other consumer FDM printer that takes 1.75mm spools, SUNLU drops in with no drama. Students grinding out thesis prints, makers building cosplay props, small shops printing jigs and fixtures, and anyone with a desk full of half-finished benchies will find a fit here. The pricing is also kind on the wallet when you’re burning through filament fast.
Print it yourself — recommended pairings
To get the most out of SUNLU, you’ll want the basics dialed in: a clean nozzle (brass works fine for PLA and PETG), a stable bed temperature, and dry storage so moisture doesn’t ruin a long print. Pair the filament with a set of flush cutters for clean post-processing, calipers for checking tolerances, and a dry box or sealed bin if your workshop sits in humid Manila air. All of those add-ons are available alongside the spools on the Circuit.Rocks 3D-printing aisle.
Bottom line: if you’ve been stretching one spool too far or paying brand-tax for filament that prints the same as everything else, the SUNLU page is the easy stop. Three solid materials, fair prices, and same-day Manila cutoff at 4PM if you order before then.
Frequently Asked Questions
Which SUNLU filament should I pick first?
If it’s your first spool, start with SUNLU PLA — it’s the most forgiving on temperatures, bed adhesion, and cooling. Move up to PLA+ 2.0 when you need parts that can take a hit, and switch to PETG when temperature tolerance or flex matters more than easy printing.
Will SUNLU filament work with my printer?
All three spools are 1.75mm at 1kg, which is the standard size for most consumer FDM printers — Ender, Neptune, Bambu A1/P1, Prusa Mini, Anycubic Kobra, and friends. Check that your printer’s hotend can hit the right temperature range (around 190–220°C for PLA, 230–250°C for PETG) and you’re good to go.
What will I learn if I start printing with SUNLU filament?
Plenty. You’ll pick up slicer fundamentals (temperatures, speeds, retraction), bed-leveling and first-layer technique, when to swap nozzles, how moisture affects print quality and how to dry filament, and the practical differences between PLA, PLA+, and PETG — knowledge that carries over to any filament brand or printer you use next.
